Real questions people ask about reMarkable, Supernote, BOOX and the eInkPads apps,
answered by Penny. Every question here has been asked more than once.
Troubleshooting
Why is my calendar blank on the tablet when it looks fine in the preview?
That is frustrating when the connection side all looks right. The usual cause is that the PDF on the tablet was built before the calendars were attached, so the feeds are connected but the file itself is still the empty one.
Work through these in order:
1. On the planner card, click Regenerate, then Push to device. Connecting a calendar does not rebuild the PDF on its own, so this is the step that actually puts events into the file.
2. Before you push, close the planner on the tablet and go back to the home screen. A document that is open on screen will not redraw with the new version, so it can look unchanged even after a successful push.
3. Check the planner Time Zone on the Calendar Feeds tab. A wrong zone shifts everything, and in edge cases pushes events outside the range being printed.
4. Check the planner Year on the General Settings tab matches the year your events are in. Events outside the planner's year will not appear.
5. Open the local copy on your computer to see whether the problem is generation or delivery: Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf. If that file has your events, the planner is building correctly and it is a delivery or refresh issue on the tablet. If it is also empty, it is a generation issue.
6. If the planner or its folder is not appearing at all on the tablet, use the Restart Tablet button in CalSync, the power icon in the left navigation. reMarkable does not always show new folders until the device has restarted once.
Also make sure you are on the current version of CalSync, since older builds had a caching problem where the tablet kept showing the old page after a cloud update. You can get the latest at https://www.einkpads.io/download.
Regenerating Your Planner
https://www.calsync.support/learn/calsync/regenerating-your-planner
If it is still blank after the regenerate and push, send it through the in-app support form, Help then Contact Support. That is the best route here because you can attach a photo of the tablet screen and the planner settings, and it arrives with your version and device details already attached. A picture settles in one message what otherwise takes several.
How do I troubleshoot a connection problem between my tablet and the app?
Annoying when it just sits there. Binder connects over SSH to the tablet itself, so it's usually one of three things. Work through them in order.
1. Get the connection details off the tablet. On the reMarkable, open Settings, then Help, then Copyright and licenses. Under the GPLv3 Compliance section you will find your device password and the IP addresses you can connect to.
2. Enter them in Binder. IP address is 10.11.99.1 if you are plugged in over USB, or the Wi-Fi IP shown on that same screen. Password is the device password from that GPLv3 section. Note that the device password changes when the tablet reboots or updates, so if it worked before and stopped, re-read it and retype it.
3. If you are on a Paper Pro, Paper Pro Move or Pure, Developer Mode has to be enabled before that password and those connection details appear at all. On a reMarkable 2 you do not need it. Worth knowing before you flip it: enabling Developer Mode wipes the device, so sync your notebooks to the reMarkable cloud first, and read reMarkable's own Developer Mode documentation since it is their toggle and their terms.
Two other common blockers. Use a data USB cable, not a charge-only one. And on Windows, SSH over port 22 has to be allowed through Windows Defender Firewall, which is the single most common cause of a Windows connection failing.
USB is more reliable than Wi-Fi, so start there if you can.
If it still will not connect, tell me your tablet model, whether you are on Windows, macOS or Linux, and whether you are going over USB or Wi-Fi, and we will keep going.
Faster still: send it through the support form inside Binder, the speech-bubble icon in the left sidebar, labelled "Get Support" when you hover it. It is the only route that takes a screenshot, and a photo of the error plus your GPLv3 screen settles this in one message. Your licence, version and device come attached automatically.
Why are some of my calendar events missing after syncing?
Sorry, that one is frustrating when most of it comes through and some of it doesn't. A few things cause "some events missing" more often than anything else, so let's rule them out in order.
1. Check the feed itself. If you added your primary calendar with a public or embed link, it may only carry a subset. In Google Calendar on a computer, hover the calendar, open Settings and sharing, then Integrate calendar, and copy the "Secret address in iCal format" that ends in basic.ics. Paste that into the planner's Calendar Feeds tab. For Outlook, publish with "Can view all details" and copy the .ics link, not the HTML one.
2. Confirm the calendar is attached to that specific planner. Calendars are added per planner, so a feed connected in Settings alone will not show up on a planner that does not list it in its Calendar Feeds tab.
3. Check the planner Time Zone on that same tab. If it is wrong, events shift and some land on the wrong day or outside the planner's year entirely.
4. Regenerate, then Push. Saving settings does not rebuild the PDF. The card has to go green, "Ready to push," before it sends.
5. Make sure you are on the current version. Older builds left deleted occurrences of repeating events on the planner, and had a caching issue where the tablet kept showing an older page. Both are fixed in the latest release.
If it still misses events after that, it helps to know what kind of items they are, all-day events, recurring ones, invitations from someone else, or events on a shared or secondary calendar, because each of those fails for a different reason.
Google Calendar (ICS feed)
https://www.calsync.support/learn/calsync/google-calendar
If you would rather hand it to a person, use the Get Support form inside CalSync, the speech-bubble icon in the left sidebar. That is the best route because you can attach a screenshot of the planner page and of your Calendar Feeds tab, and it arrives with your licence, version and device already attached. There is also support@einkpads.com, or the contact form at www.einkpads.com.
Do you keep our previous chat if I navigate away?
You do not need to. Nothing here has to stay open, and you are not losing anything by closing it.
Here is the whole thing in one place so you can walk away with it:
Check: open your planner in CalSync, click the Calendar Feeds tab, and see whether your calendar is listed there. Settings does not count, it has to be on that tab.
If it is not there, add it on that tab, then click Regenerate and Push to device. That is almost certainly your fix.
If it is there, email support with your account email, your CalSync version, that you are on a reMarkable 2, and a screenshot of that tab. They can see your account and read the feed itself.
Come back whenever you like and tell me what the tab showed. A fresh chat is fine, just say it is the reMarkable 2 with an empty planner and the feed question, and we pick up from there.
Where do synced files appear on my computer?
I don't have a documented location for where Binder keeps its templates on your computer, so I won't guess at a folder path.
The one storage path I can give you with confidence is for generated planners. CalSync keeps a copy of the file it sent to your tablet here:
Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf
That's the exact PDF that went to the device, which makes it useful for checking whether a problem happened during generation or in how the tablet renders it.
For the Binder template files specifically, ask through the support form inside Binder (Help, then Contact Support). Lead with that one because you can attach a screenshot of what you're seeing in the app, and it arrives with your licence and version attached, so nobody has to ask. support@einkpads.com works if you'd rather write an email, and there's a contact form at www.einkpads.com if neither works for you.
What does the power-button-style icon with the grey dot next to it mean?
Good, that rules out your network, and closing the planner rules out the other common one. So we are down to two possibilities: the cloud link itself, or generation never completing.
On the yellow dot, I want to be straight with you: our material only documents the red state of that indicator, which in Cloud mode is a local SSH ping and can be red while cloud sync works fine. I do not have a documented meaning for yellow, so I am not going to guess at it. It is probably not your answer either way.
Three things that will actually pin this down.
1. Settings, then Diagnose. Tell me whether the "reMarkable Cloud" test passes or fails. That one line separates a connection problem from a generation problem.
2. On the planner card, what does the status dot and its label say before you push? Green "Ready to push" means the PDF exists. Amber "Waiting to be generated" means it does not, and Push will fail no matter how good the connection is. If it is amber, click Generate on the card and watch what happens.
3. The exact error text after you click Push, word for word, and whether it appears immediately or after a delay.
If the cloud test fails, disconnect reMarkable Cloud in Settings and reconnect with a fresh one-time code from my.remarkable.com, then retry.
If Diagnose passes and the card is green and Push still errors, that is past what I can sort from here. Send support your account email and a screenshot taken right after the error appears, and note that you are on 1.7.2 and it fails on both a reMarkable 2 and a Paper Pro. That combination is worth them looking at the account directly.
What should I do if the suggested fix did not work?
You are right, and that is on me. Let me stop listing steps.
One question, one answer: open the planner, click the Calendar Feeds tab, and tell me whether your calendar is listed on that tab. Yes or no.
If no, that is the whole problem and we fix it there in one move.
If yes, then this is not something I can talk you through and it should go to support. Send them your account email, your CalSync version, that you are on a reMarkable 2, and a screenshot of the Calendar Feeds tab. They can look at the account and the feed itself rather than guessing from the outside, which is what I have been doing for the last few messages.
How do I download the Apple Silicon version of Binder instead of the Intel version?
That is a known snag with the order email, and it is easier to fix than it looks. The email lists two Mac downloads on adjacent lines and they read almost identically, so the second one gets clicked by mistake.
Here are both, direct:
Apple Silicon (M1 / M2 / M3 / M4)
https://www.einkpads.io/api/binder/darwin/arm64/releases/latest
Intel Mac
https://www.einkpads.io/api/binder/darwin/x64/releases/latest
The Apple Silicon link is the one with "arm64" in it. Intel is "x64".
To confirm you got the right file, check the name in your Downloads folder before unzipping. It should be binder-pro-darwin-arm64-<version>.zip for Apple Silicon, and binder-pro-darwin-x64-<version>.zip for Intel.
If you are not certain which Mac you have, click the Apple menu, then About This Mac. If it says Chip with an Apple M name, you want Apple Silicon. If it says Processor with an Intel name, you want Intel.
You can also always grab the current builds from https://www.einkpads.io/download, which shows both Mac options side by side and is easier to click accurately than an email.
Why won't the downloaded Binder installer run?
That is the first-run welcome screen, and it is normal. The authorize step usually comes after you move past it, so start by clicking through whatever the welcome screen offers, a Continue or Get Started button.
If you land somewhere that never asks for a licence, tell me what buttons are on the welcome screen and what you see once you click through, and I will point you at the right place rather than guess at a menu name.
One thing worth checking while you are there: if the app shows a plan anywhere and it says Trial, that is expected until the licence is entered. Once you do enter it, close CalSync fully and reopen it, because it caches the plan locally.
Your licence key and the purchase email address are both in the order email that carried this download.
Download and activate CalSync

Why does the app keep opening the learning centre instead of the screen I want?
First, a correction from my last message: that "connect-calendar-accounts" link was wrong, it is not a real lesson. Sorry for sending you chasing it.
On your question, there is no URL for opening a planner. Planners live in the CalSync desktop app on your computer, so you open CalSync, go to Planners, and click the planner you want. The one exception is Pro and Business, where you can go to epcalsync.com in a browser, sign in with the one time code we email you, and open your planners there.
The lessons that actually cover this:
Create your first planner
https://www.calsync.support/learn/calsync/create-your-first-planner
Google Calendar
https://www.calsync.support/learn/calsync/google-calendar
Why do I get a server error when validating my licence?
That is usually the licence check being blocked on its way out, not a problem with the key itself. CalSync validates against api.keygen.sh, and security software, a VPN or a DNS filter will stop that call even though your browser works fine.
Work through these in order.
1. Confirm you are entering the key in CalSync and not Binder. They look similar in a search and people activate the wrong app more often than you would think.
2. Use the email address you purchased with, exactly as it appears in your order email, along with the License Key from that same email.
3. In your antivirus or security app, allow the CalSync app and add einkpads.io and api.keygen.sh as exceptions, then turn OFF HTTPS or web scanning for those domains. Allowing alone is not enough, the scanning has to be bypassed.
4. Disconnect any VPN, and if you use a DNS filter like Pi-hole, NextDNS or AdGuard, allowlist those two domains. A quick test: put the computer on your phone's hotspot and try activating again. If it works there, your normal network is the cause.
5. Check the computer's date, time and time zone are correct. A wrong clock breaks secure connections and produces exactly this kind of error.
6. Make sure you are on the current build. Older versions had activation bugs that are fixed now, and you can grab the latest at https://www.einkpads.io/download.
If it does go through but the features stay locked, click the EP logo in the top left corner to force a licence refresh, then quit and reopen the app.
Here is the walkthrough for downloading and activating:
Download and Activate
https://www.calsync.support/learn/calsync/download-and-activate
If none of that clears it, tell me your operating system and the exact wording of the server error, and I will take it from there.
Why does the app revert to the previous version after I install an update?
That is annoying, and it usually means the new build is installing somewhere other than the copy you are actually launching, rather than the update failing.
A few things to check, in order:
1. Quit CalSync completely (Quit, not just closing the window) before installing. An installer landing on a running app can leave the old copy in place.
2. Install from the direct links rather than the auto-updater, so you know exactly which build you got:
Apple Silicon (M1 / M2 / M3 / M4)
https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest
Intel Mac
https://www.einkpads.io/api/calsync/darwin/x64/releases/latest
Windows
https://www.einkpads.io/api/calsync/win32/releases/latest
Linux
https://www.einkpads.io/api/calsync/linux/x64/releases/latest
3. On a Mac, make sure you drag the new app into /Applications and replace the existing one, then launch from Applications. If you are opening it from the Downloads folder or from a mounted disk image, you will keep running whatever build lives there.
4. On Windows, uninstall the existing CalSync first, then run the fresh installer, and launch from the Start menu rather than an old shortcut.
I do not have anything in our material that explains a build genuinely rolling itself back to 1.4.1, so if it still reports 1.4.1 after a clean install from those links, that needs a real look at your machine.
The fastest route for that is the in-app support form: the speech-bubble icon in the left sidebar, labelled "Get Support" when you hover it. Use that one because you can attach a screenshot of the version number, and it arrives with your licence, version and device already attached. You can also write to support@einkpads.com, or use the contact form at www.einkpads.com.
Downloading and activating, if it helps to see it done:
https://www.calsync.support/learn/calsync/download-and-activate
Why can't I reach the activation page on my Mac?
...security tool, allow the CalSync app itself and add einkpads.io and api.keygen.sh as exceptions. Allowing is not enough on its own, you also need to turn off HTTPS or web scanning for those two domains. That is the usual reason the browser works fine but CalSync sits there.
Also check your Mac's date, time and time zone are correct, since a wrong clock breaks the secure connection to the licence server.
So, three things back from you when you get a moment:
1. What buttons or options are on the Welcome screen.
2. What happens when you click the one that should move you forward.
3. Whether you run any antivirus, VPN or DNS filtering on that Mac.
With those I can tell you whether this is the installer, the network, or something on the account.
Download & Activate
https://www.calsync.support/learn/calsync/download-and-activate
Why won't the downloaded CalSync file open on my Mac?
Good, that is the piece we needed. Unzipping only unpacks the files, it does not install anything, which is exactly why nothing is showing up in the Start menu.
1. In File Explorer, open the unzipped CalSync folder in Downloads. Double click the folder itself to go inside it.
2. Look for a file with a .exe on the end and the CalSync icon. If your file extensions are hidden, use the Type column instead and look for Application.
3. Double click that file.
4. If Windows shows a blue "Windows protected your PC" box, click More info, then Run anyway. That is normal for a freshly downloaded installer.
5. Let it finish, then press the Windows key and type CalSync. It should now appear under Apps. Right click it and choose Pin to taskbar so you never have to hunt again.
6. Open it and, under "Authorize this computer," enter the email you purchased with and your licence key from your purchase email.
Once the app is open and authorized, the Connect screen is where you add your tablet, and I will walk you through that next.
Download and activate CalSync
https://www.calsync.support/learn/calsync/download-and-activate
If there is no .exe inside that folder, tell me what file names you do see and I will tell you which one to run.
Nothing happens when I try to use the app, what should I do?
That button works over a local connection to the tablet, so if you are connected through reMarkable Cloud it often has nothing to act on. Look at the small dot near that power button at the top: if it is red, there is no local connection, which is why nothing happens. On Cloud that red dot is normal and does not mean cloud delivery is broken.
Two things to do instead:
1. Restart the tablet by hand using its own power button, then look again under My files, eInkPads, Planners.
2. While it is rebooting, confirm the push really succeeded. Check the app says Connected at the top, and open the built file on your computer at Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf. If that PDF exists and looks right, generation is fine and this is purely a delivery or display problem.
Also worth doing: update CalSync if you have not recently. Several reMarkable Cloud delivery and caching bugs were fixed in later builds. https://www.einkpads.io/download
If the planner still is not on the tablet after a manual restart, this is the point to hand it to a person. Use the Get Support form in the app, the speech-bubble icon in the left sidebar. Attach a photo of your tablet's My files screen and a shot of CalSync's planner list. Those two pictures usually settle it in one message, and the form already carries your licence, version and device.
How do I allow CalSync through my firewall so my device responds on port 22?
That is normal, and it means the Privacy check was a dead end rather than a finding. macOS only lists an app under Files and Folders after that app has actually asked for access, so an app that has never tried to write there simply is not shown. There is no way to add it by hand from that screen.
So drop that thread. The thing that actually matters is what the planner card does.
1. Open CalSync and go to Planners.
2. Tell me what the status dot on the card says: amber "Waiting to be generated" or green "Ready to push".
3. Click Generate on the card itself, not Save on the settings, and watch the card for a few seconds. Note anything that changes, a spinner, an error, the dot changing colour, or genuinely nothing at all.
4. Also tell me your CalSync version, from the app.
If clicking Generate does nothing at all and no einkpads folder appears in Documents afterwards, that is a support case rather than a setting you can flip. Send them your account email, your macOS version, your CalSync version, and a screenshot of the planner list taken right after you click Generate.
How do I reset everything and start over from scratch?
Happy to help you reset, though it is worth knowing that "start over" can mean two quite different things in CalSync, and the wrong one costs you more work than you need.
What I can tell you confidently:
1. Planner setups. Everything about a planner, including its calendar feeds, lives in that planner setup in the app. Calendars are added per planner, so removing a planner takes its feeds with it. Rebuilding is Planners, then New Planner, and you set the name, year, device, type, theme and time format again.
2. Tablet connection. If the connection is what has gone wrong, you do not need to touch your planners at all. In Settings you can disconnect your reMarkable Cloud and reconnect with a fresh one-time code from my.remarkable.com. Codes expire quickly, so grab it and paste it straight in.
3. Generated files. The PDFs CalSync built are on your computer under Documents/einkpads/devices/[device-id]/planners/, and the copies already on your tablet stay where they are. Pushing a rebuilt planner updates the same file rather than duplicating it.
One caution if you are on Pro or Business: your planner setups sync across every computer on your account, so clearing them on one machine is not a local-only act.
I do not have a documented, safe path for wiping the whole account or licence state back to factory, and I would rather not guess at one. If that is what you are after, use the in-app support form: the speech-bubble icon in the left sidebar, labelled "Get Support" when you hover it. That is the best route because you can attach a screenshot, and it arrives with your licence, version and device already attached, so nobody has to ask. If you would rather write, support@einkpads.com works, or the contact form at www.einkpads.com.
If you tell me what went wrong in the first place, there may be a shorter fix than starting over.

Getting started
How do I contact customer support?
Yes, that would be support@einkpads.com. That one is ours, so I can repeat it freely.
Before you use it, though, one thing worth knowing. If your question is about CalSync or Binder, the support form inside the app is the better route. Open the app, go to Help, then Contact Support. It is the only way to attach a screenshot or a photo of your tablet screen, and it arrives with your licence, version and device already attached, so nobody has to ask you for any of that. A photo usually settles in one message what takes four rounds of description by email.
If you would rather write an email, support@einkpads.com works fine. And if neither of those suits, there is a contact form at www.einkpads.com.
If you tell me what you are stuck on, I may be able to sort it here without you waiting on a reply.
Where do I find CalSync on my computer after installing it?
CalSync is a desktop app, so it lives on your computer, not on the tablet. Download it from www.einkpads.io, or use the direct links below, which always give you the current version:
Apple Silicon (M1 / M2 / M3 / M4)
https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest
Intel Mac
https://www.einkpads.io/api/calsync/darwin/x64/releases/latest
Windows

Linux
https://www.einkpads.io/api/calsync/linux/x64/releases/latest
Not sure which Mac you have: Apple menu, then About This Mac. If it says Chip with an Apple M name, take the Apple Silicon one. If it says Processor with an Intel name, take the Intel one.
If you have not bought a licence yet, purchases happen at www.einkpads.com. If you already have one, install the app, open it, and under "Authorize this computer" enter the email you bought with and your licence key, both of which are in your purchase email.

Once it is activated, connect the reMarkable from the Connect screen:
https://www.calsync.support/learn/calsync/connect-remarkable
What is the current version of CalSync?
You are right, and I was wrong to say otherwise. If the download page lists v1.7.2, then you are already on the current build and there is nothing to update. Sorry for sending you to check something I should not have assumed.
So that rules out the last easy explanation. You are on the newest version, all three files came out of the same calendar app by the same export route, your local and planner zones are correct, and two feeds still land two hours off while the third is right. There is nothing left on your side to adjust.
Send it to support as a bug against 1.7.2, with:
1. The three .ics files attached, if you can.
2. The DTSTART and DTEND lines from one wrong event and one correct event, so the Z form and any TZID are visible side by side.
3. What each of those shows on the planner page, and what it should show.
4. Your planner's Time Zone setting and your local zone.
5. A note that all three were exported the same way from Apple Calendar, and that only the Microsoft-sourced one renders correctly.
That last point is the one that will get it reproduced quickly. It tells them the problem tracks with the event's original format rather than anything about your setup.
What is the difference between CalSync and Binder?
Two different jobs, and it's easy to mix them up because they both live on your computer and both talk to your tablet.
CalSync builds a planner. It reads your calendars (Google, Outlook, iCloud, CalDAV or a published .ics link), turns them into a navigable PDF planner with tap-to-jump navigation, and pushes that file to your tablet. You use it to see your year, your weeks and your days on the device, and with Task Markup it can print your to-do list on the pages too.
Binder installs templates, covers and sleep screens onto an e-ink tablet. It is not a calendar tool. It puts PNG templates onto a reMarkable so they show up natively in the template picker when you create or edit a notebook.
The short version: CalSync is for calendars and planners, Binder is for the templates behind your notebook pages. Plenty of people run both, they don't overlap.
One thing worth knowing if you're looking at Binder: templates are PNG files and need Binder to install them, but PDF planners and documents do not. Those go across with reMarkable's own app.
Both are on www.einkpads.io if you want to download and compare, and purchases happen at www.einkpads.com.
What is CalSync?
CalSync exists to solve one problem: your calendar lives on a screen you are trying to spend less time looking at, and your tablet is where you actually think. It turns your real calendars into a proper paper-feeling planner on the tablet.
What you get out of it:
1. Your actual events, not a blank template. It reads Google, Outlook, iCloud, CalDAV, or any published .ics link, and prints your meetings onto the day, week and month pages.
2. It stays current. Regenerate and push and the planner updates, and your handwriting stays. CalSync swaps the underlying pages but keeps your ink and any pages you have pinned, so you can write across updates without losing anything.
3. Scheduled pushes. Turn on automatic push in Settings and it keeps itself up to date. Basic is capped at once every 24 hours, Pro unlocks 15 minutes through 12 hours.
4. Navigation that works on e-ink. Tap to jump between months, weeks and days, plus a Today button on the cover and day pages that lands you on the current day.
5. It works with your tablet, whichever one that is. reMarkable over Cloud or direct USB and Wi-Fi, Supernote over Supernote Cloud, and anything else, BOOX included, through Universal Mode.
6. Tasks on the page. Task Markup prints Todoist, Microsoft To Do, Google Tasks or CalDAV tasks onto your day pages, and a check with your pen completes the task on the platform. Included on every paid plan. Apple Reminders is not supported.
7. It only ever reads your calendar. It never creates, edits or deletes an event.
If you go Pro, the additions are eP Cloud, where our servers rebuild and deliver the planner while your computer is asleep, the QR code on your planner opening Year Insights on your phone, 5 computers instead of 2, and planner setups syncing between those computers. The plan comparison is at www.einkpads.io/pro, and purchases happen at www.einkpads.com.
Best way to see what it feels like is to watch a planner get built:

How do I download and install updates?
CalSync has a built-in updater, so most of the time it handles itself: it downloads and installs new versions in the background, and you pick them up the next time you fully close and reopen the app. That last part matters, a restart is what actually lands the update.
If you want to be certain you are current, reinstall over the top with the latest build. It keeps your planners and your activation, and the links below always point at the newest release.

Can I open the learning centre in a separate tab without leaving the app?
A few practical ways to keep the steps in front of you while you work in CalSync:
1. Copy the steps out of this chat and paste them somewhere that stays visible: a notes app, a text file, or a browser tab you can flip to. Then resize the CalSync window so it sits beside it rather than fullscreen.
2. Print the steps, or save them as a PDF, if you would rather not juggle windows. On Windows that is Ctrl and P, on a Mac Command and P, then Save as PDF.
3. On a Mac you can also use Mission Control or split view to have CalSync on one side and the steps on the other. On Windows drag CalSync to one edge of the screen for snap layout, then put the steps in the other half.
If you are on macOS or Windows and want the exact split-screen keystrokes, tell me which one and I will give you those.
Worth saying: this chat itself does not persist as a saved document on your account, so if you want these steps later, copy or print them now.
Is there a mobile app?
Not on a plan below Pro, no. CalSync is a desktop app, so the planner is built and pushed from your computer. There is no phone app that does it.
The phone route exists, it just sits behind Pro. With Pro you scan the QR code printed on your planner and that planner opens on your phone, where you can push a fresh copy to your tablet. Or go to epcalsync.com in any browser, enter your account email and the one-time code we send you, and your planners are listed there. On Vault, Ad Hoc or Basic you can still sign in, but instead of the planner list you get a note saying planner sync is a Pro feature.
Worth saying: with Pro you would not often need the phone anyway, since our servers push on a schedule without anything of yours being awake. The phone page is more for when you want a fresh copy right now.
Plan comparison is at www.einkpads.io/pro, and if you already own CalSync the upgrade happens inside the app.

What AI are you?
I am Penny, the support assistant for eInkPads. I am an AI, not a person, and I am not going to get into the technical details of what is running underneath.
If there is something about CalSync, Binder or your tablet you want sorted out, that I can help with. What are you working on?
Is the app available in other languages such as Spanish?
Claro, seguimos en español.
Cuéntame qué necesitas y te ayudo: en qué tableta estás (reMarkable, Supernote, BOOX u otra), qué producto usas (CalSync, Binder) y qué está pasando exactamente.
Un detalle útil de antemano: las lecciones del Learning Center están en inglés, pero puedo explicarte los pasos en español sin problema.
How do I use the setup wizard to download and activate the software?
Activation covers a few different failures, so here is the short triage while you get the wording to me.
1. Check you are in CalSync and not Binder. They install side by side and a search can launch the wrong one.
2. Use the email you purchased with and the License Key from that same purchase email, in the Authorize this computer panel.
3. If the key validates but everything stays locked, click the EP logo in the upper left corner to force a refresh, then quit CalSync fully and reopen it.
4. If it says the network is blocked or it cannot reach the server, that is usually security software or a VPN. Allow the CalSync app and add einkpads.io and api.keygen.sh as exceptions, and turn off HTTPS or web scanning for those two. Allowing alone is not enough, which is why the browser works and the app does not.
5. If it says you have too many devices, that is your plan's computer limit. Vault and Ad Hoc get 2, Pro 5, Business 10. Remove a machine you no longer use, or ask support to adjust it.
Here is someone walking through download and activation end to end.
Download and Activate
https://www.calsync.support/learn/calsync/download-and-activate
If none of that clears it, reply to your purchase email with the screenshot and the exact message. Licence and account corrections have to be made by a person on our side.
What's new in the latest version?
I do not have release notes for 1.7.2 in front of me, so I would be guessing if I listed anything, and I would rather not.
What I can tell you for certain about the versions just before it:
1. 1.7.0 added Task Markup with Todoist.
2. 1.7.1 added Microsoft To Do, Google Tasks and CalDAV Tasks, and fixed the bug where the Google, Outlook and iCloud connect buttons wrongly showed a PRO badge on non-Pro paid plans.
For what actually shipped in 1.7.2, check the download and release page at www.einkpads.io, or let the built-in updater pull it and I can help with anything that looks different once you are on it.
I have finished the setup steps, what do I do next?
Then let's find out whether the events are missing at generation or in delivery. That local copy answers it in one step.
1. On your computer open the generated PDF at Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf. That is the exact file sent to your tablet.
2. If that PDF has your events, the build is fine and the tablet is showing you an older copy. Update CalSync to the current version, click Regenerate then Push again, and use the Restart Tablet button in CalSync's left nav, the power icon. Older builds had a cloud caching issue where the tablet kept rendering the previous version.
3. If that PDF is also blank, the feed is not returning events. Back in the planner's Calendar Feeds tab, check the connected Microsoft account has the specific calendar ticked and listed for this planner. Signing in to the account is one step, attaching the individual calendar to the planner is another, and it is easy to stop after the first.
4. While you are there, confirm the Time Zone and that the planner Year matches the year your events sit in.
One correction from my last message: I gave you a lesson URL that does not exist. The right one is here.
Outlook and Microsoft 365
https://www.calsync.support/learn/calsync/microsoft-outlook
Tell me which of those two the PDF turns out to be and we will go from there.
Can you show me my previous question?
There is nothing above this on my end. This is the first message in our conversation, so I have no earlier context to look back at, only what you just told me about the Chromebook.
Tell me what you were working on and I will pick it back up. Useful things to include: which product you are using, CalSync or Binder, which tablet you have, and what you were trying to get done.
If you were partway through something with a human on the support side, that thread lives in the ticket rather than here. The in-app support form is the best place to continue it, since it arrives with your licence, version and device attached and you can add a screenshot. It is the speech-bubble icon in the left sidebar, labelled "Get Support" when you hover it.
Syncing and pushing
Why is my push not updating my tablet?
Most often that is the tablet not refreshing, not a failed push. Work through these in order.
1. Restart the tablet from inside CalSync, the power button icon in the left nav. reMarkable often does not display a newly created folder until the device has restarted at least once. This is the fix in the large majority of cases.
2. Check where you are looking. Planners land under My files, then eInkPads, then Planners, unless you changed the target folder in Settings.
3. Make sure the planner actually generated. The card shows a status dot: amber "Waiting to be generated" means no PDF exists yet and Push is greyed out. It needs to be green, "Ready to push," before Push does anything.
4. If an older version of the planner is on the tablet but not the newest one, update CalSync, then Regenerate and Push again. Older builds had a device-side caching issue where the tablet kept showing the previous version. Also close the planner on the tablet, the home screen is enough, before pushing, since an open document will not redraw.
5. If the tablet is on reMarkable Cloud, let it sync on Wi-Fi for a minute after the push.
To check the file really was built, look on your computer at Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf. If it opens there, the problem is delivery or display, not generation.
Connect your reMarkable
https://www.calsync.support/learn/calsync/connect-remarkable
If none of that shakes it loose, use the Get Support form in the app, the speech-bubble icon in the left sidebar. Best route because you can attach a photo of the tablet screen, and it arrives with your licence, version and device already attached.
Does my calendar regenerate and push automatically?
Two sides to this, and the computer side is where the actual setting lives.
On the computer:
1. Connect your tablet first. Go to the Connect screen, pick your device and connect. If you are in Universal Mode, the auto push options are hidden by design, because there is no device to push to.
2. Make sure the planner has at least one calendar in its Calendar Feeds tab, and that the planner has been generated once so its status dot is green, "Ready to push."
3. Open Settings, go to Calendar Settings, and turn on "Automatically push updated planners to your device."
4. The "Frequency" dropdown only appears after that toggle is on. Pick your interval. Basic is capped at every 24 hours. Faster intervals, 15 minutes, 30 minutes, hourly, 6 hours and 12 hours, need Pro, Business or Vault.
One thing to know: scheduled auto push runs from the desktop app, so the computer needs to be awake and CalSync running. If you want pushes to happen with the computer closed, that is eP Cloud on Pro and Business, connected from a planner's Sync tab.
On the tablet:
There is no auto push setting to enable on the device itself. Just keep it on Wi-Fi so it pulls the new file, and close the planner when you are done writing. A document left open will not redraw with the updated version, and fresh ink does not upload while it is open. Back to the home screen is enough.
Optional, but it pairs well: in the reMarkable's own PDF settings choose "Last visited page" so the planner reopens where you left off, and use the printed "Today" button to jump to the current day.
Planner Customization
https://www.calsync.support/learn/calsync/planner-customization
How do I get my calendar onto my tablet?
Short version: you build a planner in CalSync on your computer, attach your calendar to it, then push it to the tablet.
1. Open CalSync and go to the Connect screen. Pick your device and how you want to connect. On a reMarkable the easiest route is reMarkable Cloud: open the Cloud tab, click "Get a one-time code," sign in at my.remarkable.com, paste the 8 character code in and click Connect. Supernote uses Wi-Fi and Cloud sign-in. Anything else, BOOX included, uses Universal Mode.
2. Go to Planners and click New Planner. On the General Settings tab set the Name, Year, Device, Type, Theme and Time format, watching the live preview.
3. Open that planner's Calendar Feeds tab and add your calendar. You can sign in directly to Google, Outlook, iCloud or CalDAV, or paste an ICS link. Set the planner Time Zone here too, since wrong times almost always trace back to that.
4. On the planner card click Generate. The status dot turns green and says "Ready to push."
5. Click Push to device. Over reMarkable Cloud the file lands in your chosen folder and the tablet picks it up on its next sync. If the folder does not appear the first time, use the Restart Tablet button in CalSync, the power icon in the left nav.
Then turn on auto push in Settings, Calendar Settings, so it keeps itself current.
Walkthroughs for the two steps people usually want to see done:
Create your first planner
https://www.calsync.support/learn/calsync/create-your-first-planner
Connect your reMarkable
https://www.calsync.support/learn/calsync/connect-remarkable
Tell me which tablet you have and I can trim this down to just your path.
Does syncing still happen when my computer is off or the desktop app is closed?
Right, closing the lid usually puts the laptop to sleep, and a sleeping machine is not running anything, so no scheduled push happens while it is shut. When you open it again and it wakes, CalSync picks back up and pushes on its next scheduled run.
If you want it to keep working with the lid down you would have to stop the machine sleeping, which is an operating system setting rather than anything in CalSync, and it needs to stay on Wi-Fi too. Most people find that more trouble than it is worth on a laptop.
That gap is exactly what eP Cloud on Pro removes. You connect a calendar once from a planner's Sync tab, and our servers fetch your events, rebuild the planner and deliver it on a schedule with your laptop asleep, closed, or in a bag. The plan comparison is at www.einkpads.io/pro, and if you already own CalSync you upgrade from inside the app rather than the store.
eP Cloud Sync
https://www.calsync.support/learn/calsync/ep-cloud-sync
Why isn't my content syncing after installing the app on a second computer?
Straight answer: on Vault, no, the two laptops will not sync their planner setups. Cross-device Planner Sync is a Pro and Business feature. So you have two options.
Option 1, stay on Vault. Build the planner setup again on the second laptop with New Planner, same name, year, style and calendar feeds. It is manual work once. Worth knowing you will not end up with two planners on the tablet: when the second laptop pushes, it updates the same file already in your reMarkable cloud, so nothing is duplicated. What you would be maintaining is two copies of the setup, and any change you make on one laptop you have to make on the other by hand.
Option 2, add Pro. Then your planner setups, with their calendar feeds attached, sync between both laptops automatically. Start on the desktop, carry on with the laptop, nothing to move by hand. That is exactly the behaviour you are describing.
Two things about Pro that matter to you specifically:
1. Pro does not replace Vault. It sits on top of it. If you cancel Pro later, your lifetime Vault licence is still there.
2. One Pro subscription covers 5 computers, not one per machine. You do not buy it twice.
Pro also includes eP Cloud, where our servers fetch your calendars and deliver the planner on a schedule with both laptops closed, which makes the question of "which laptop am I on" mostly disappear.
You upgrade from inside CalSync, not on either website. The plan comparison is at https://www.einkpads.io/pro if you want to read what is included and what it costs before deciding.
Learning Center: eP Cloud Sync
https://www.calsync.support/learn/calsync/ep-cloud-sync
Why is my calendar stuck in "waiting to be generated" so nothing pushes to my tablet?
It means the PDF has not been built yet. Saving a planner's settings does not generate it, that is a separate step, and the Push button stays greyed out until a generate finishes.
The status dot on the planner card tells you where you are:
1. Amber, "Waiting to be generated" means no PDF exists yet, so there is nothing to send.
2. Green, "Ready to push" means the PDF is built and you can send it to your tablet.
So click Generate on the planner card itself. When the dot turns green, Push becomes available.
If you click Generate and it stays amber, note any error that appears and make sure you are on the current build, since older versions had generation problems that are fixed now. Latest is at https://www.einkpads.io/download.
Worth watching someone do the whole first run through:
Create your first planner
https://www.calsync.support/learn/calsync/create-your-first-planner
Where do synced files appear on my tablet?
Then let us drop it. That local copy was only ever a shortcut for diagnosing, and it is not worth more of your time. Finder search skips some locations by default, and if Documents lives in iCloud Drive with storage optimised, things get slippery. None of that changes what is on your tablet.
The question I still need answered is the one from the tablet itself. Open the planner on the reMarkable and turn to a day you know has events on it.
Which is it:
1. The day pages are completely blank, no events anywhere.
2. There are events, but they are old or incomplete.
3. Something else, for example the pages look wrong or the wrong year.
If it is blank, the first thing to check is the planner's Calendar Feeds tab in CalSync. A calendar connected in Settings is not automatically attached to a planner, and that is the single most common reason for a planner that builds fine and comes out empty. Confirm your calendar is listed on that tab, then check the Year on General Settings matches the year of your events.
Tell me which of the three you are seeing, and I will give you the exact next step rather than another list.
Can I sync to more than one tablet?
Two different things could be behind that question, so here is both.
One calendar showing on more than one tablet
Calendars are attached per planner, not globally. Open the planner, go to its Calendar Feeds tab, add the calendar there, set the planner Time Zone, then Regenerate and Push. If you want that same calendar on a second tablet, build a planner for that device too and add the same calendar feed to it. There is no limit on how many tablets you own.
Adding a calendar feed:
https://www.calsync.support/learn/calsync/google-calendar
One calendar setup shared between your computers
That is cross-device Planner Sync, and it is Pro and Business only. Your planner setups, with their calendar feeds attached, sync between every computer signed in to the same account. Install CalSync on the second computer, activate it with the same license and email, and the planners pull across when you open the planner list. You can also click the Planner Sync button, the cloud icon at the top right of the list. One subscription covers 5 computers on Pro, 10 on Business, so you do not buy it twice.
On Vault, Ad Hoc or Basic you will see a gold dashed "Sync across devices (PRO)" button instead. Those plans still get scheduled auto push, just not the cross-computer sync.
If what you actually want is your planner refreshing without your computer being on, that is eP Cloud, part of Pro and Business. You connect the calendar once from a planner's Sync tab and our servers do the fetching and delivery.
https://www.calsync.support/learn/calsync/ep-cloud-sync
Tell me which of the three you meant and which plan you are on, and I will narrow it down.
Connecting a tablet
Where is the connect screen in the app?
That FAQ link I gave was also one I made up, not something in our material. Twice now. Ignore both and go by what I write out here.
On the "Connected" wording: that is the status text at the top of the CalSync window, next to the tablet restart button, the one that looks like a power icon. If you are not in Universal Mode and a device is selected, that area is where CalSync tells you whether it can currently reach the tablet. I do not want to describe it more precisely than that because I would be guessing at the layout of your build.
Now, Vault on Windows. Vault does include the faster push intervals, so this should just be a setting:
1. Open Settings.
2. Go to Calendar Settings.
3. Turn on "Automatically push updated planners to your device."
4. A "Frequency" dropdown appears directly below it. Pick your interval.
Two things about Vault specifically, so nothing surprises you later.
Auto push runs from your PC, so CalSync has to be open and the machine awake for it to fire. Server-side delivery with the computer off is eP Cloud, which is Pro and Business only.
And if you see a gold dashed "Sync across devices (PRO)" button in the planner list, that is a different feature, keeping planner setups in step across multiple computers. It is not the auto push you are after, and it is normal for it to be locked on Vault.
Real walkthrough, this one is from our material:
Planner customization and sync on interval
https://www.calsync.support/learn/calsync/planner-customization
If the toggle is already on and it still is not pushing, tell me how the PC connects to the tablet, reMarkable Cloud or direct over USB or Wi-Fi, and we will go from there.
Which devices are supported?
Good, that keeps it simple. On a reMarkable 2 there is no Developer Mode to worry about, so it comes down to the tablet being reachable on your network.
1. On the tablet, open Settings, then Help, then Copyright and licenses. Scroll to the GPLv3 Compliance section. That is where your device password and the available IP addresses are listed. Note the Wi-Fi IP, not 10.11.99.1.
2. Check the tablet and your computer are on the same network. Same SSID, no guest network, and no VPN running on the computer.
3. In CalSync, on the Connect screen pick reMarkable and choose the Direct connection. Enter that Wi-Fi IP and the device password exactly as shown, including case.
4. On Windows, allow SSH on port 22 through Windows Defender Firewall. Start, then Windows Defender Firewall with Advanced Security, run as admin, Inbound Rules, New Rule, Port, TCP, port 22, Allow the connection.
Two things that trip people up: the device password changes if the tablet has been reset, so re-read it rather than using an old one, and the Wi-Fi IP can change when the router hands out a new lease, so re-check it if it worked yesterday and not today.
If that still will not go through, USB is the more reliable path. Plug in a data cable, on the tablet turn on Settings, then Storage, then USB web interface, and use 10.11.99.1 with the same password.
Connect your reMarkable
https://www.calsync.support/learn/calsync/connect-remarkable
Tell me if you are on Windows, macOS or Linux and what CalSync says when it fails, and we can go further.
Can I limit access to USB in some way?
Short answer: yes, if you have a reMarkable. CalSync has a Direct connection that runs over a USB cable, no cloud account involved.
How to set it up:
1. On the tablet, turn on the USB web interface: Settings > Storage. On a Paper Pro, Paper Pro Move or Pure you enable Developer Mode instead, and note that enabling it wipes the device, so back up first.
2. Get your Device Password from the tablet: Settings > Help > Copyright and licenses, under GPLv3 Compliance.
3. In CalSync, on the Connect screen pick reMarkable, choose Direct, enter IP address 10.11.99.1 and that device password.
4. Use a data USB cable, not a charge-only one. On a Mac, click Allow if macOS asks about the accessory. On Windows, allow SSH (port 22) through the firewall.
Two things worth knowing. Pen write-back for Task Markup over a Direct connection is arriving in CalSync 1.7.3, so on earlier versions marks read back only over reMarkable Cloud. Delivery over USB works on any version.
If you have a Supernote, that one connects over Wi-Fi and Supernote Cloud, not USB. For a BOOX or anything else, Universal Mode builds the PDF on your computer and you copy it across by USB yourself, which is USB-only in practice.
reMarkable connection walkthrough
https://www.calsync.support/learn/calsync/connect-remarkable
What is the known IP setting in the app?
For a direct connection to a reMarkable, that field takes one of two values:
1. Over USB, enter 10.11.99.1. That is the same for every reMarkable and it is the more reliable of the two, so start here if you have the cable.
2. Over Wi-Fi, enter the Wi-Fi IP address your tablet reports, something like 192.168.x.x. Your computer and the tablet have to be on the same network.
You find the Wi-Fi IP, and the device password that goes in the field next to it, on the tablet itself:
1. Open Settings.
2. Go to Help.
3. Open Copyright and licenses.
4. Look under the GPLv3 Compliance section. The device password and the available IP addresses are both listed there.
Two things that trip people up. On a reMarkable Paper Pro, Paper Pro Move or Pure, Developer Mode has to be enabled before that password and those addresses appear at all, and enabling it wipes the tablet, so sync your notebooks first. On a reMarkable 2 you do not need Developer Mode, just turn on the USB web interface in Settings, Storage. And on Windows, allow SSH on port 22 through the firewall or the connection will time out.
If this is CalSync and you only want planners on the tablet, you can skip the IP and password entirely by connecting over reMarkable Cloud with a one-time code.
Connect your reMarkable
https://www.calsync.support/learn/calsync/connect-remarkable
Tell me which tablet and which app you are in, plus USB or Wi-Fi, if it still will not connect.
Billing and plans
What features are included in CalSync Pro?
Here is what Pro actually changes, in the order most people care about.
Your computer stops being part of the loop. This is eP Cloud. You connect a calendar once from a planner's Sync tab and our servers take over: they fetch your latest events, rebuild the planner and deliver it to your tablet on a schedule, with your laptop asleep, closed or packed away. iCloud, Google, Microsoft and CalDAV servers like Fastmail or Nextcloud all work this way. Pro includes 1 cloud planner and 150 cloud pushes a month.
Your planner on your phone. Scan the QR code printed on any page and that planner opens on your phone. From there you can push a fresh copy to your tablet, or open Year Insights to see events so far, scheduled hours, clear days, your fullest day, Work and Life balance, your next free evenings, and charts by day, week and year. You can also go to epcalsync.com in any browser and sign in with a one-time code we email you, no password.
Five computers instead of two. Your licence covers CalSync on 5 machines. Vault and Ad Hoc get 2. That is computers running CalSync, not tablets, and there is no limit on tablets.
Planner sync across those computers. Your planner setups, with their calendar feeds attached, sync between every computer signed in to the same account. Start on the desktop, carry on with the laptop. One subscription covers all 5, you do not buy it twice.
Faster automatic pushes. Scheduled auto push exists on every plan, but Basic is capped at once every 24 hours. Pro unlocks 15 minutes, 30 minutes, hourly, 6 hours and 12 hours.
Ten calendar feeds, same as Vault and Ad Hoc.
Two things worth knowing so you do not pay for something you already have: signing in directly to Google, Microsoft, iCloud and CalDAV is on every paid plan, as are unlimited summary pages, every planner style and layout, all languages and tap-to-jump navigation. What Pro changes is not whether you can connect a calendar, it is whether our servers can use that connection while your computer is off.
And if you already own Vault, Pro sits on top of it. Cancel Pro later and your lifetime Vault licence is still there.
The full side-by-side comparison, including what Monthly costs, is at www.einkpads.io/pro. If you already own CalSync, do the upgrade from inside the app rather than the store.
How do I request a refund?
I can help you get to the right place, but I should be straight with you first: we do not offer refunds on digital products once they have been delivered. What we can do is store credit toward any future purchase at eInkPads, and those requests are looked at case by case.
If it is a physical item like the Journey bag, that is a different process and does get returned.
So two things from you:
1. Which product is this, and was it a digital licence (CalSync, Binder) or a physical item?
2. What went wrong?
I ask the second one because most of what sends people to a refund request is something I can fix in a couple of steps, and a lot of it comes down to an outdated build or a connection being blocked. If you would rather just take the store credit, say so and I will pass it along.
Why does my app still show my old plan after I paid for an upgrade?
That label goes stale sometimes, and it usually is not a billing problem.
First, check the rest of the screen before doing anything:
1. Look at the device allowance under the plan label. If it reads "out of 5 devices," your account is Pro.
2. Look at the badge in the bottom left corner of the app. If it says PRO, you are on Pro and only the label is wrong.
If both of those look right, quit CalSync completely, using Quit rather than just closing the window, then open it again. The label reads correctly after a full restart, because the app caches the plan locally.
If it still says Basic after that restart, or if the device allowance also reads "out of 2 devices," that is a real account issue. Send us your account email and we will check the entitlement on our side and correct it.
Why am I prompted to upgrade when connecting my calendar even though I already have a lifetime plan?
Short answer: no. Direct Google, Outlook and iCloud sign-in is included on every paid plan, Vault included. That PRO badge is a display bug in older builds, not a limit on your licence.
From CalSync 1.7.1 the calendar connect buttons work the same on all plans. Update the app and the badge disappears. If you connected a calendar earlier and it now shows a padlock, updating unlocks that too.
1. Download the current build for your machine:
- Apple Silicon: https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest
- Intel Mac: https://www.einkpads.io/api/calsync/darwin/x64/releases/latest
- Windows: https://www.einkpads.io/api/calsync/win32/releases/latest
- Linux: https://www.einkpads.io/api/calsync/linux/x64/releases/latest
2. Install it over the top and reopen CalSync.
3. Open your planner's Calendar Feeds tab and click Google. It should take you straight to the normal Google sign in.
For the record, Vault includes 10 calendar feeds and unlimited summary pages. What Pro actually adds is eP Cloud, so our servers rebuild and deliver your planner while your computer is off, plus planner sync across computers and faster auto push intervals. None of that is needed just to connect Google.
Here is the walkthrough for connecting the account:
Connect Google, Outlook & iCloud
https://www.calsync.support/learn/calsync/connect-calendar-accounts
How much does the Pro plan cost?
No puedo darte cifras aquí, porque los precios cambian y no quiero decirte uno que no sea el actual. Pero te digo exactamente dónde verlos.
1. Para comparar planes de CalSync (Vault, Basic, Ad Hoc, Pro, Business) y ver qué incluye cada uno, entra en www.einkpads.io/pro.
2. Para comprar, el precio aparece en la tienda: www.einkpads.com.
3. Si ya tienes CalSync y quieres subir de plan, hazlo desde dentro de la propia app, no desde la web.
Dime qué producto te interesa, CalSync o Binder, y te explico qué trae cada nivel para que la comparación te sirva de algo.
Do you offer any discount codes?
Not something I can confirm either way. Discounts and promotions aren't something I have visibility into, and I won't guess at a programme that may not exist.
Two places to check. The store at www.einkpads.com shows any pricing or offers currently running. And for a question like this, a person is the right answer, since it's an account and purchase matter rather than a product one.
Use the support form inside CalSync or Binder, the speech-bubble icon in the left sidebar, labelled "Get Support" when you hover it. It arrives with your licence and version attached, and it's the only route that takes screenshots if you need to show proof of service. Otherwise support@einkpads.com, or the contact form at www.einkpads.com.
Do I need a subscription to connect a calendar and keep it updated?
Without Pro, your computer is the thing doing the syncing. CalSync fetches your calendars itself and pushes the updated planner to your tablet, but only while the app is running on that machine. Close the laptop and nothing updates until you open it again.
Two ways to keep it current:
1. By hand: on the planner card click Regenerate, then Push to device.
2. On a schedule: Settings, then Calendar Settings, turn on "Automatically push updated planners to your device." A Frequency dropdown appears once the toggle is on. Basic is capped at every 24 hours; Vault and Ad Hoc can pick faster intervals. Leave CalSync running and it handles the rest.
Two things that trip people up. The auto-push toggle is hidden in Universal Mode, because there is no device selected to push to, so connect your tablet first. And close the planner on the tablet before a sync, the home screen is enough, otherwise the tablet keeps showing the page it already rendered.
Your calendar connections themselves are not limited by plan. Signing in directly to Google, Outlook, iCloud or CalDAV works on every paid plan. What Pro adds is our servers doing the fetch and delivery while your computer is off.

Planners and layouts
Can CalSync show my Todoist tasks in my planner and let me check them off with the pen?
Task Markup is the feature you want, and it is included on every paid plan. Two parts: connect the platform, then tell the planner what to print.
1. Open Settings and find the "Your todo lists" section. Connect your platform there. Todoist uses a personal API token, which you get from Todoist Settings under Integrations, Developer. Microsoft To Do and Google Tasks use a normal sign-in. CalDAV Tasks takes a server, username and app password, and works with Fastmail, Nextcloud, Synology and Zoho.
2. Open your planner and go to its Tasks tab.
3. Add the platform as a task source.
4. Route each project or list to Top Three, the Tasks section, or off. You can feed one planner from more than one platform.
5. Regenerate the planner and push it to your tablet.
Where tasks land: a task with a due date prints on that day's page, an overdue task moves to today with a struck copy left on the original day, an undated task lives on today, and a completed task prints checked on the day it was finished.
Once they are on the page, your pen works on them. A check always means complete, on every platform. A dash pushes the due date to the next day. On Microsoft To Do a dot sets In Progress and a circle sets Waiting On Others. On CalDAV an X becomes a real cancelled state. CalSync never deletes anything on any platform.
One habit that matters: close the planner on the tablet, the home screen is enough, before you sync. Tablets upload fresh ink lazily while a document is open, and that is the usual reason a checkmark seems not to have registered.
Two things worth knowing. Apple Reminders is not supported, since Apple moved it to CloudKit with no public API. And if you do not see buttons for Microsoft To Do, Google Tasks or CalDAV, update CalSync from einkpads.io, they arrived in 1.7.1.
There is a walkthrough with audio that shows the whole setup:

What does the QR code in the planner do?
That changes the picture, thank you. Summary pages are their own thing in CalSync, separate from the planner's day and week pages, and they are included without limit on every paid plan. The trial is the only thing that caps them.
What I cannot confirm from my material is what a note-taking summary page is meant to render, whether that is ruled lines, a blank writing area or something else. I would rather say that than invent a page layout for you.
Here is the walkthrough for summary pages, which shows how they are added and what comes out:
Summary Pages
https://www.calsync.support/learn/calsync/summary-pages
Two practical checks while you are in there:
1. A summary page you have added only appears after a fresh build. Click Regenerate on the planner card, wait for the status dot to go green, then Push to device. Saving the setting alone does not rebuild the PDF.
2. If the page comes out and it is genuinely empty, that is worth reporting. Use Help, then Contact Support inside the app, because it sends a screenshot of the generated page along with your version and plan. A picture of the blank page is the fastest way to get a straight answer on whether it is a bug or working as designed.
How do I view a future year such as 2027 in my planner?
Fair enough, my mistake, scratch that theory. If the planner year and the event date both sit in 2026, the year is not the problem.
At this point the useful thing is to find out which half is failing: the building of the file, or the delivery of it. Two ways to do that, pick whichever is easier.
The quick one: build a fresh test planner. Planners, New Planner, name it Test, year 2026, then on its Calendar Feeds tab add your Apple calendar and set Europe/Amsterdam. Generate it, wait for the status dot on the card to turn green and say Ready to push, then Push. If the test planner has events and the original does not, the original planner's setup is at fault and we rebuild it. If the test is blank too, the feed is returning nothing useful and the problem is upstream of the tablet.
The other one: open the generated PDF on the Mac rather than the tablet. Instead of hunting in Finder, in CalSync note the planner and use the path Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf, or paste that folder path into Finder with Go, then Go to Folder. If the PDF is blank on the Mac, delivery is fine and generation is the issue. If it has your events, the file on the tablet is the wrong or stale copy.
One thing I should flag on the iCloud side. Signing in there needs an app-specific password created at account.apple.com, not your normal Apple ID password. If a regular password was used, the connection can look accepted and still bring back nothing.
Do the test planner, tell me whether it is blank as well, and if it is, I will hand this to support with your account email and everything you have already given me, because at that point it is not something you should be debugging further.
How do I get a planner onto my tablet?
Straightforward on a reMarkable 2, and you do not need Developer Mode for it.
1. Open CalSync and go to the Connect screen. Pick reMarkable, then open the Cloud tab.
2. Click "Get a one-time code." That opens my.remarkable.com, where you sign in and get an 8 character code.
3. Paste the code into CalSync and click Connect. The top of the app should then say Connected.
4. Go to Planners and click New Planner. On the General Settings tab set the Name, Year, Device, Type, Theme and Time format, watching the live preview.
5. Open the Calendar Feeds tab and add your calendar, and set the planner Time Zone while you are there. Calendars are attached per planner, so this step is what keeps the pages from coming out empty.
6. On the planner card click Generate. The status dot goes from amber "Waiting to be generated" to green "Ready to push." Push stays greyed out until that finishes.
7. Click Push to device. The planner lands in eInkPads > Planners under My files, and your tablet picks it up on its next sync.
If the folder does not appear the first time, click the Restart Tablet button in CalSync's left menu, the one shaped like a power button. reMarkable often will not show a brand new folder until the device has restarted once.

Create Your First Planner
https://www.calsync.support/learn/calsync/create-your-first-planner
How do I navigate back from a task page to the calendar in my planner?
From the tasks page the reliable move is the Today button, if that page carries one. Tap it and you land on the current day's page, which puts you back in the calendar flow, and from a day page the month and year links take you up a level.
What I cannot tell you honestly is whether your particular planner style prints a dedicated back link on the checklist page itself. That varies by planner type and theme, and I do not want to send you tapping at a spot that has nothing under it.
Two practical fallbacks in the meantime:
1. Use the reMarkable page thumbnail view, the pages icon at the top of the open document, and scroll back to the month or day page you want.
2. Favourite or pin the month page you use most, so it is one tap from the document menu.
If you can send a photo of the checklist page you are looking at, someone can tell you exactly which marks on that page are tappable. Use the Get Support form in the app, the speech-bubble icon in the left sidebar. It is the only route that takes screenshots, and it arrives with your planner style, version and device already attached.
Where do I choose where a task list appears in my planner?
That section is part of Task Markup, and it only appears from the versions that shipped it, so an older build simply will not show it. Todoist arrived in CalSync 1.7.0, and Microsoft To Do, Google Tasks and CalDAV Tasks came in 1.7.1.
Update the app and it should be there:
1. CalSync has a built-in updater, so let it update, or grab the current build directly.
2. Apple Silicon: https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest
3. Intel Mac: https://www.einkpads.io/api/calsync/darwin/x64/releases/latest
4. Windows: https://www.einkpads.io/api/calsync/win32/releases/latest
5. Linux: https://www.einkpads.io/api/calsync/linux/x64/releases/latest
6. Reopen CalSync, go to Settings, and look for "Your todo lists."
Worth knowing: Task Markup is included on every paid plan, so this is not a plan limitation. Only the free trial keeps you on the sample calendar.
Once you see the section, you connect your platform there (Todoist uses a personal API token, Microsoft and Google use a normal sign-in, CalDAV takes a server, username and app password), then open the planner's Tasks tab to route each list.
There is also a Task Markup walkthrough with audio in the Learning Center, worth watching before you set it up.
If the section still is not there after updating, send a screenshot of your Settings screen through Help, then Contact Support in the app. That route takes attachments and arrives with your version and licence already attached, so a photo settles it in one message. If you would rather email, support@einkpads.com works, and there is a contact form at www.einkpads.com.
Templates and covers
How do I upload my own template?
Short answer: I don't have anything in our material that says you can drop your own template file into a planner's summary pages, so I don't want to invent a menu path for it. What I can tell you is that summary pages themselves are unlimited on every paid plan, and they're configured per planner in CalSync rather than imported.
Two things worth separating, since they get mixed up:
1. Summary pages are pages CalSync builds into the planner PDF from your calendar data. The options live in the planner's settings.
2. Binder is the product that installs your own templates, covers and screens onto the tablet. Those show up in the reMarkable template picker for notebooks, not inside a generated planner.
So if what you actually want is your own design on the tablet, Binder is the route. If you want it inside the planner, that's a different thing and I'd rather have someone confirm what's possible than guess.
Here's the summary pages walkthrough, which shows what the built-in options cover:
Summary Pages
https://www.calsync.support/learn/calsync/summary-pages
If that doesn't get you what you're after, send it through the support form inside CalSync (Help, then Contact Support). That's the best route because you can attach a screenshot or a mockup of the template you have in mind, and it arrives with your licence and version already attached. If you'd rather write an email, support@einkpads.com works, and there's a contact form at www.einkpads.com if neither suits.
How do I set up carousel?
Happy to help. The Daily Event Carousel has two hard requirements before anything else matters: it only works on a reMarkable over a direct connection with Developer Mode enabled, so not in Universal Mode and not over reMarkable Cloud, and you need at least one calendar connected.
Assuming that is your setup:
1. Open CalSync and connect your reMarkable. The top of the app should say "Connected."
2. Check the planner has at least one calendar feed in its Calendar Feeds tab.
3. Go to Settings, then Daily Event Carousel.
4. Turn on Enable Daily Event Carousel.
5. Under Calendars to include, pick the calendars you want shown, or leave it empty to include all of them.
6. Optionally turn on Keep screen blank when no events, if you would rather see a blank screen on empty days than reMarkable's default images.
7. Generate and sync your planner. CalSync builds the sleep screen images from today's events and sends them across.
The carousel only refreshes when the planner is generated or synced, so if you are seeing yesterday's events, a re-sync fixes it. Turn on Auto Sync and it keeps itself current.
Today Event Carousel
https://www.calsync.support/learn/calsync/today-event-carousel
If it still is not showing, tell me whether the app says "Connected" and which step you get stuck on. If you want to send a photo of the tablet screen, use the support form inside CalSync, the speech-bubble icon in the left sidebar labelled "Get Support" when you hover it. That is the only route that takes screenshots and attachments, and it arrives with your licence, version and device already attached, so a photo settles in one message what otherwise takes four.
Why isn't there a note-taking template in CalSync?
Fair point, and I am not going to bluff here. My support material covers planner types, styles, themes and layouts, but it does not document a note-taking category or what it is supposed to produce, so I cannot tell you whether that is a template that should be appearing, a section that gets added to the planner, or a labelling problem in your version.
Two things that would sort it quickly:
1. Make sure you are on the current CalSync build, since a fair number of "this option does nothing" reports turn out to be older versions. You can get the latest at https://www.einkpads.io/download.
2. If it is still empty after that, send it to support through the app: Help, then Contact Support. Use that route rather than email, because it takes a screenshot of the screen you are looking at and arrives with your version and plan already attached. One picture of that category selected settles what would otherwise take several messages of describing it.
If you paste me the exact wording you see on that screen and the planner type you picked, I will tell you what I can confirm from my side in the meantime.
Info on every template bundle?
The planner styles and layouts you pick in CalSync aren't loose files sitting in a folder you can browse. They're built into the app, and CalSync draws the planner from them when you generate. So there's no templates directory for those, and I don't have anything documented that says otherwise.
What does land on your computer is the finished planner:
Documents/einkpads/devices/[device-id]/planners/[planner-id]/[planner-id].pdf
That's the exact file CalSync sent to your tablet, one per planner.
If you're trying to get at a style to modify it, that isn't something our material covers, and I'd rather not invent a path for you to go hunting in. Send it through the support form inside CalSync (Help, then Contact Support) and say what you want to change. That route is best because you can attach a screenshot of the style you mean, and it arrives with your licence and version already on it. Otherwise support@einkpads.com, or the contact form at www.einkpads.com.
Here's the planner styles walkthrough, in case what you actually want is already an option in there:

Accounts and licences
Why are features still locked after I enter my licence key?
That's a frustrating place to be stuck. Let's work through the usual causes, in order.
1. Make sure you are actually in CalSync and not Binder. They look similar in a search result, and people sometimes activate a CalSync key inside Binder.
2. Check the two fields. "Authorize this computer" wants the email you purchased with and the licence key exactly as it appears in your purchase email. Copy and paste rather than typing, and watch for a trailing space at the end of the pasted key.
3. If it says the licence validated but everything still looks locked, click the EP logo in the upper left corner to force a refresh of the licence state. If that does not do it, quit CalSync completely (Quit, not just closing the window) and reopen it.
4. If it will not reach the licence server at all, that is usually security software or a VPN. In your antivirus app, allow the CalSync app and add einkpads.io and api.keygen.sh as exceptions, and turn OFF HTTPS or web scanning for them. Allowing alone is not enough, which is why the site opens fine in a browser but the app cannot connect. Disconnect any VPN and reopen CalSync.
5. Antivirus can also block CalSync from writing licence data to the AppData folder, which makes the activation appear to succeed and then vanish. Adding the app as an exception covers this too.
6. If you are on an older build, update. Grab the current version at https://www.einkpads.io/download and try again.
Here is the walkthrough for download and activation:
Download and Activate CalSync
https://www.calsync.support/learn/calsync/download-and-activate
If none of that clears it, send us the details through the app: Help, then Contact Support. That route is best because you can attach a screenshot of the exact error, and your licence, version and device come through automatically, so nobody has to ask you for them. If you cannot get into the app, support@einkpads.com works, or the contact form at www.einkpads.com.
How do I move my licence and data to a new computer if I no longer have access to the old one?
Straightforward. Your licence covers more than one computer, so you install on the new one and authorise it with the same details.
1. Download CalSync for the new machine. Apple Silicon: https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest, Intel Mac: https://www.einkpads.io/api/calsync/darwin/x64/releases/latest, Windows: https://www.einkpads.io/api/calsync/win32/releases/latest, Linux: https://www.einkpads.io/api/calsync/linux/x64/releases/latest
2. Open it, and under "Authorize this computer" enter the email you bought with and your License Key, both from your purchase email.
3. Connect your tablet again on the Connect screen, since the connection is per computer.
About your planners. On Pro or Business your planner setups, with their calendar feeds attached, sync across every computer signed in to the same account. Open the planner list on the new machine and they pull across, or click the Planner Sync button, the cloud icon at the top right of the list. On Vault, Ad Hoc or Basic there is no cross-computer sync, so you recreate the planners with New Planner. When you push, they update the same files already on your tablet, so nothing gets duplicated.
Device slots: Vault and Ad Hoc 2, Pro 5, Business 10. If the old computer is going away and you hit the limit, remove it or write in and we can adjust it.

How do I get my licence key if I have not received it?
That one is on us to fix, and it needs a person who can look at the purchase, since anything involving your order details belongs in a private ticket rather than here.
Two quick things to check first, because they solve it more often than you would think:
1. Your licence key is in the purchase confirmation email, not a separate message. Search your inbox for eInkPads, and check spam and promotions, since those emails carry download links and get filtered.
2. If you bought through the store, the confirmation can take a few minutes to arrive.
If it is still not there, get support to reissue it:
1. Best option: open CalSync or Binder, go to Help, then Contact Support. You can attach a screenshot there, for example your order receipt, and the message arrives with your version and device details already attached. The app opens and lets you reach that form even before it is activated.
2. Or send a message to support@einkpads.com.
3. Or use the contact form at www.einkpads.com.
If you have not installed the app yet, here are the current builds:
Apple Silicon: https://www.einkpads.io/api/calsync/darwin/arm64/releases/latest
Intel Mac: https://www.einkpads.io/api/calsync/darwin/x64/releases/latest
