Your records stay yours.

This policy applies to Quit Smoking: 21-Day Taper / 止吸-21天减量戒烟. The developer does not operate an account system or a server that receives your health or habit records.

Information the developer collects

None. The developer does not collect personal information, usage analytics, advertising identifiers, location, contacts, or your smoking, coffee, alcohol, and spending records. The app contains no ads, tracking technologies, or third-party analytics SDKs.

On-device storage and widget sharing

Your plan, entries, preferences, progress, and badges are stored locally on your device. The main app and its widget use Apple’s App Group container on the same device so the widget can display today’s progress and accept quick entries. This data is not uploaded to a developer-operated server.

App Store trial and purchase

All app features are available without activating a trial from August 22 through August 31, 2026. On September 1, the app returns to its standard Apple StoreKit 2 model: a zero-cost 3-day trial and an optional one-time lifetime unlock. The trial does not renew, become a subscription, or charge automatically when it ends. Apple may process transaction and Apple Account information under Apple’s policies. The developer does not receive your Apple Account password or full payment information.

Retention and deletion

Local records remain on your device until you remove them through the app, reset the app, or delete the app. Deleting the app may permanently erase local records. StoreKit can restore eligible trial or lifetime purchase access for the same Apple Account, but Apple and the developer cannot restore deleted habit records.

Children and policy changes

The app is not directed to children. If this policy changes, the updated policy and effective date will be published on this page before the change takes effect.

Health disclaimer

This app is a behavioral planning and health education tool. It does not provide medical advice, diagnosis, treatment, or emergency services, and it does not replace a qualified healthcare professional. Seek professional medical advice for quitting tobacco or for symptoms and medication questions. For an emergency, contact your local emergency service.
