Privacy policy

What data the app and this site process — and what they do not. No account, no cloud sync, no analytics in the app. Full text in German.

This privacy policy is written and maintained in German, which is the authoritative version for the app and this site. In short: your study data (test results, bookmarks, preferences) stays in a local database on your device and is never sent to us. The app shows Google AdMob ads behind Google’s consent prompt, and sells an optional one-time Pro unlock through Google Play Billing, managed by RevenueCat. There is no account, no cloud sync and no analytics or crash-reporting SDK in the app. Read the full policy in German, or contact us in any of the app’s languages.
