Your study data stays yours.

Data the app stores

The app stores study progress, review history, learning preferences, and language settings in a local SQLite database on your device. This data is used only to run the learning experience, including scheduling reviews and showing progress.

Data collection and tracking

The app does not require an account and does not collect or transmit your study data to the developer. It contains no advertising, analytics, or tracking SDKs, and it does not track you across apps or websites.

Sharing and external links

If you choose to export attribution information, the app opens the system share sheet. You decide which destination receives that content. Links in the Credits & Licenses screen open in your browser. Those destinations operate under their own privacy policies; the app does not receive data about what you do there.

Removing your data

Choose Settings → Reset all progress to delete study cards and review history stored by the app. Deleting the app also removes its locally stored data, subject to your device and backup settings.

Support messages

If you email support, the message and return address you provide are used only to respond to your request and maintain necessary support records. Please do not send sensitive personal information.
