Stamp Book privacy policy

Effective 27 September 2026 · Developer: Igor Diachuk

Stamp Book keeps your habits, drawings and completion history on your device. You do not need an account, and we do not receive your habit records.

Your book and drawings

The app stores habit names, stamp drawings, ink colors, shapes, completion dates and app preferences locally. The app, widgets, Control Center actions and Shortcuts share the same on-device storage through an Apple App Group. Stamp Book does not operate a server for this data or sync it through its own cloud service.

Local app data may be included in backups managed by Apple, depending on your device settings.

Purchases

Apple processes payments and subscriptions for Stamp Book Pro. Stamp Book uses Apple's StoreKit framework to display products, verify transactions, restore purchases and determine whether Pro is active. We do not receive your payment card details. The app does not use RevenueCat or another purchase analytics service. Apple's processing is covered by Apple's privacy policy.

No advertising or tracking

Stamp Book has no advertising, third-party analytics, tracking SDKs or AI services. Your drawings and habit history are not sent to us for analysis. The app does not request access to your contacts, location, camera or microphone.

Deleting your data

You can remove a completion by pressing and holding its stamp in the book. To delete a habit and its history, press and hold its card in Records and confirm the deletion. Deleting the app removes its local data, subject to Apple's backup and device-storage behavior. Deleting the app does not cancel an Apple subscription; manage subscriptions in your Apple Account settings.
