Important compatibility notes

For all Android 4.1 and all Samsung users: There's an Android bug that maybe causes accounts to be lost after a device reboot. To avoid this issue, please install the free app "DAVdroid JB Workaround". Samsung users: The problem doesn't occur if you download DAVdroid using Samsung Store or Amazon Store.

On some Android 4.4.2 devices, DAVdroid accounts will disappear after an app update. If you experience this issue, please install the free app "DAVdroid JB Workaround". Details: http://davdroid.bitfire.at/faq/entry/account-gone-after-updating

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 / Lightning / etc. on your laptop / PC

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)!
