Die Kartei is designed with privacy as a core principle. All AI processing happens entirely on your device — no data is sent to external servers, no cloud processing occurs, and no account is required.
Die Kartei does not collect, store, transmit, or share any personal data. This includes:
All AI inference, flashcard generation, and German language processing runs locally on your iPhone using on-device models. No internet connection is required after initial model downloads.
The only network activity Die Kartei performs is downloading AI models from their respective providers when you explicitly choose to download a model. No user data is transmitted during this process.
Die Kartei does not integrate with any third-party analytics, advertising, or tracking services.
All app data — including flashcard decks, study history, and downloaded models — is stored locally on your device. Deleting the app removes all associated data.
Die Kartei does not collect data from anyone, including children under 13.
If this privacy policy is updated, the new version will be posted at this URL. Since Die Kartei collects no data, meaningful changes are unlikely.
