Privacy Policy - ankidroid/Anki-Android GitHub Wiki

AnkiDroid does not collect or transmit any information on you or your activities by default.

At your option, and only after you grant permission, AnkiDroid may send crash traces to a crash collection service wholly owned and operated by AnkiDroid. These crashes will contain information about your device and the current AnkiDroid configuration settings, and is used to troubleshoot and fix errors with the program.

At your option, and only after you grant permission, AnkiDroid may collect and transmit application usage information to Google Analytics. This may include information about your device and AnkiDroid configuration, and informs the developers which features are being used, and how they are being used, in order to focus limited developer time on features people care about enough to use. The service is configured in such a way that the data is not then re-shared with Google or any others, and is as anonymous as is possible by configuration in the Analytics settings.

Use of the AnkiWeb cloud sync functionality is completely optional, and is governed by it's own privacy policy, available here: https://ankiweb.net/account/privacy
