App data
Deck names, card text, grading counts, review times and the current session are saved in the device library. The app does not collect them or use analytics, advertising, tracking, camera or microphone.
There is no advertising SDK. The developer does not collect personal data through the app.
Selecting a CSV may ask your file provider to download that file. Deleting a deck removes its local records and associated session. Device backups and Apple purchase records are managed separately by their providers.
Purchases
StoreKit contacts Apple for products, purchases and restoration. The app uses verified purchase entitlements. The developer does not receive card numbers or payment details. Apple manages transaction records and refunds.
Storage and deletion
Manage local settings and records using the app's deletion controls or by removing the app. Keychain credentials, shared copies, device backups and provider records may require separate management.
