Important compatibility notes

Attention: DAVdroid must not be moved to the SD card! This will cause strange behaviour, including account and data loss.

Get the best out of this app ...

... when using with your own DAV server (Radicale, DAViCal, SabreDAV, Baikal, ...) and HTTPS - so you own and control all your data while having the comfort of synchronization between various devices. Or use a hosted DAV service you trust or the one of your company.

... and combine it with Evolution / Thunderbird / etc. on your computer

Why is it secure?

Source code is available (see homepage)

No need for giving your contacts/calendars to Facebook, Google, etc. Use your own server (or a trusted one)!

TLS is recommended to protected your communication so synchronization is secure even when using open Wi-Fi networks.
