Easy to Use

EteSync is very easy to use. Our app seamlessly integrates with existing Android apps so you won't even notice you are using it. Security doesn't always have to come at a cost.

Secure & Open

Thanks to End-to-End encryption, not even we can see your data. Don't believe us? You shouldn't, just verify yourself, all of the code is open source.

Change Journal

A full history of your data is saved in a secure and integrity-checked journal which means you can review, replay and revert any changes made to it at any point in time.

How does it work?

EteSync integrates seamlessly with Android. All you need to do is sign up and install the app. After a quick setup, you will be able to save your contacts and calendar events to EteSync using your existing Android apps, and EteSync will transparently encrypt your data and update the change journal in the background. More security, same work-flow.

What's next?

EteSync works great for calendars and contacts on Android (import included!), and on the desktop (beta DAV proxy), but much more is planned.

The next item on our list is an API for 3rd party apps to interact with the journals which will make it possible to sync more data types than just contacts and calendars.

After that, we would like to also implement shadow journals, journals that are synced across devices, but not exposed to the underlying system. This can be used, for example, to implement secret contact lists that are not exposed to other Android apps.
