Data stored on your device
Fasting stores preferences, plans, achievement progress, fasting records, and weight records locally on your device. You do not need an account, and the app does not upload these records to the developer's servers. Reminders are managed on the device. App Lock uses system authentication; the app does not receive or store your biometric data.
Usage analytics
The app uses Google Firebase Analytics to collect limited pseudonymous usage information, such as app launches, sessions, screen interactions, subscription product selections, purchase outcomes, and basic device and app information. This helps us understand how features are used and diagnose purchase issues. Fasting records, weight records, plans, achievements, feedback content, biometric data, payment credentials, and Apple transaction identifiers are not sent as analytics events. The app has no advertising or cross-app tracking. Google processes analytics data under its Privacy Policy and the retention settings of the linked Google Analytics property.
Feedback and purchases
When you send feedback from the app, the email draft includes your device model, system version, app version, language, time zone, and screen information. You can review or remove this information before sending. Apple handles purchases and subscriptions; the app does not receive your payment details.
Deletion and contact
You can delete the fasting records, weight records, plans, achievements, and settings on this device from Me > Clear Data. This does not delete analytics data already processed by Google or cancel an Apple subscription. For privacy questions, email liyong.bj@hotmail.com. We will update this page if our data practices change.
