When you enter your login data (DAV server URL, user name, password) in DAVx⁵, these data will only be used for transferring them to the server you specified (including redirect locations given by this server, if applicable).

User name and password are stored using Android's account manager and not by DAVx⁵ itself. Client certificates are taken from Android's secure keystore and are not readable by DAVx⁵ itself. To protect your login data, consider to encrypt your device.

Contacts, events and tasks (which will probably contain personal data) are stored by the respective Android content providers and not by DAVx⁵ itself. DAVx⁵ only uses these data to synchronize them with the given CalDAV/CardDAV service. Keep in mind that other apps on your Android device (including contact and calendar apps and Android backup) may use and transfer the data according to their policies.

Except from synchronizing address books, calendars and task lists with the given CalDAV/CardDAV service, DAVx⁵ doesn't collect, process or transmit any personal or statistical data like app or server usage. There is no tracking and there are no ads.¹

Location permissions: You may have to grant coarse and fine location permission in DAVx⁵. This permission is needed if you turn on the "Sync over WiFi" option with a specified SSID.

We're not accessing, processing or transferring this data in any way, and we are not tracking your location.
