This covers our applications — eP CalSync and Binder — and the templates and files we sell: what you get when you buy one, what you may do with it, which tablets it works with, and where our responsibility ends and your tablet manufacturer's begins.
You are buying a licence to use our software, not the software itself. We keep ownership of it. Your licence is personal to you, is not transferable, and lasts for as long as the plan you bought — perpetual for a one-time purchase, or the term of your subscription.
A licence may be activated on the number of devices your plan allows. You can move a licence between your own machines by deactivating one and activating another.
A licence found to be shared publicly can be revoked. We would rather talk to you first — if you need more seats, ask.
eInkPads is not affiliated with, endorsed by, or a partner of reMarkable, Supernote, BOOX, Amazon, Apple or any other tablet manufacturer. We are an independent company making software that works with their devices.
This matters practically: your tablet's manufacturer did not build our software, does not support it, and is under no obligation to. If you contact them about a problem with our software, expect them to tell you it is not theirs — because it isn't. Come to us instead.
Product names and trademarks belong to their owners and are used here only to say which devices our software works with.
"Supported" means we test against the device and will fix our software when it breaks. It does not mean the manufacturer approves of it, and it does not mean every feature works on every model — some features need a particular kind of connection, and not every tablet offers one.
reMarkable tablets run a Linux-based operating system. That is why the tablet ships with components licensed under the GPL and LGPL, and why reMarkable provides the owner with root shell access to the device — reMarkable states on its own support site that this access is offered in compliance with the GPL v3 licence, and prints the credentials for it on the tablet under Settings › General › About › Copyright and licenses.
We mention this for one reason: when our software uses a direct connection, it is using access reMarkable built, documented and provided deliberately. It is not a workaround or an undocumented hole.
It does not mean reMarkable's own software is open source — reMarkable owns its proprietary software and says so in its licence agreement. The GPL-licensed parts are components bundled into the product, not the whole of it.
We publish a full, connection-by-connection account of exactly what eP CalSync and Binder read and write on a reMarkable, what they never touch, and how to undo any of it: What our software does to your reMarkable.
If you have been told that our software voids your reMarkable warranty, please read that page and then tell us what you were told. There is a section on it explaining what reMarkable itself publishes about this.
Supernote connects over its own cloud service or your local network. BOOX, Kindle Scribe, iPad and anything else use Universal Mode, where we build the file on your computer and you move it across with the tablet's own tools. Universal Mode touches nothing on your device.
Both applications run on your computer. Neither installs anything that runs on your tablet — no background service, no launcher, no alternative interface, no modified firmware. What they do is connect, transfer files, and disconnect.
The full technical detail, including the exact directories written to and the things we never touch, is on the reMarkable disclosure page. If you want the same detail for another device, ask and we will publish it.
Tablet manufacturers change their software. An update can move a file location, close a connection method, or change how a device authenticates, and any of those can stop part of our software working until we catch up.
When that happens we fix it as fast as we reasonably can and say so in the release notes. What we cannot do is promise it will never happen, or guarantee that a manufacturer will keep any particular connection method available. Buying our software is not a guarantee that a third party will not change theirs.
We release updates that fix problems and add features. Subscription plans receive them for as long as the subscription runs. Perpetual licences receive updates for the major version you bought.
If we ever stop supporting an application entirely, we will say so publicly and give at least 90 days' notice before any part of it that depends on our servers is switched off.
Where our software holds a credential — a calendar account, a tablet device password, a cloud token — it is encrypted, never logged, and never returned to any client. Cloud connections you authorise can be revoked by you at any time, from your account with that provider, and revoking them immediately ends our access.
What we do with the data itself is set out in our privacy policy.
Our software is provided as it is. We do not promise it will be uninterrupted or error free, or that it will suit a particular purpose you have in mind — which is why we give you a free demo, free tools and our email address before you buy rather than after.
That said, nothing here removes a right you have under the consumer law where you live. If the software is faulty or does not do what we said it does, you have rights this policy cannot exclude. See our return and refund policy for how to raise it, including the appeal form.
Email support@einkpads.com. If something in this policy is unclear or looks wrong, tell us — we would rather rewrite it than argue about what it meant.
