EteSync - Secure Data Sync

Secure, end-to-end encrypted, and privacy respecting sync for Android, the desktop and the web. Currently supports calendars, contacts and tasks (using OpenTasks), with more on the way.

In order to use this application you need to have an account with EteSync (paid hosting), or run your own instance (free and open source). Check out https://www.etesync.com/ for more information.

Easy to Use

===========

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

Secure & Open

============

Thanks to zero-knowledge end-to-end encryption, not even we can see your data. Don't believe us? You shouldn't, just verify yourself, both the client and server are open source.

Full History

=========

A full history of your data is saved in an encrypted tamper-proof journal which means you can review, replay and revert any changes you have made at any point in time.

How does it work?

===============

EteSync integrates seamlessly with your existing apps. All you need to do is sign up (or run your own instance), install the app, and enter your password. After that, you will be able to save your contacts, calendar events and tasks 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.

面向Android，台式机和网络的安全，端到端加密和隐私保护同步。目前支持日历，联系人和任务（使用OpenTasks），并且还有更多功能。

为了使用此应用程序，您需要拥有一个EteSync帐户（付费托管），或运行您自己的实例（免费和开源）。请访问https://www.etesync.com/了解更多信息。

易于使用

===========

EteSync非常易于使用。它与Android无缝集成，因此您甚至不会注意到正在使用它。安全性并不总是必须付出代价的。

安全与开放

============

归功于零知识的端到端加密，甚至我们也看不到您的数据。不相信我们吗？您不应该只是验证自己，客户端和服务器都是开源的。

完整的历史

=========

完整的数据历史记录保存在加密的防篡改日志中，这意味着您可以随时查看，重放和还原所做的任何更改。

它是如何工作的？

===============

EteSync与您现有的应用程序无缝集成。您需要做的就是注册（或运行您自己的实例），安装应用程序并输入密码。之后，您将能够使用现有的Android应用程序将联系人，日历事件和任务保存到EteSync，并且EteSync将透明地加密您的数据并在后台更新变更日志。安全性更高，工作流程相同。
