Notifications and reminders
HydroFast uses Android local notifications for hydration reminders, fasting reminders, motivation reminders, snooze actions, and notification action buttons.
- HydroFast may request Android notification permission.
- Notification permission helps local reminders appear on the device.
- Notification actions may include Log water, Snooze 15 min, Start Fast, and End Fast.
- Notification taps may route users to relevant app screens such as Water or Fast.
- HydroFast does not require a remote push notification backend for the confirmed reminder behavior.
Android home screen widget
HydroFast includes an Android home screen widget that can show hydration summary, fasting status, and quick actions such as adding water, starting a fast, ending a fast, or opening the app.
The widget uses app state from the device to display relevant hydration and fasting information.
Android permissions
HydroFast may request Android permissions required for app features.
| Permission | Purpose |
|---|---|
| POST_NOTIFICATIONS | Used to show local reminders and notification action buttons on supported Android versions. |
TODO: Update this table if the final Android build uses additional permissions.
Third-party services and SDKs
Some apps use third-party SDKs for analytics, crash reporting, ads, payments, subscriptions, or other services. Based on the current confirmed HydroFast feature brief, final third-party data behavior still needs owner review.
- TODO: Confirm whether analytics SDKs are used.
- TODO: Confirm whether crash reporting SDKs are used.
- TODO: Confirm whether advertising SDKs are used.
- TODO: Confirm whether subscription/payment SDKs are active.
- TODO: Confirm whether RevenueCat or any purchase SDK is included in the final production build.
- TODO: Confirm whether any cloud backend or remote storage is used.
Before publishing, this section must match the final app build and Google Play Data safety form.
Data sharing
Based on the current confirmed local-first app behavior, HydroFast is designed to keep tracking data on the device. If future versions add cloud sync, analytics, crash reporting, advertising, subscriptions, or backend services, this section must be updated.
TODO: Confirm final data sharing behavior before publishing.
Data retention and deletion
HydroFast stores local app data on the device for as long as the user keeps the app data. Users can use the reset data option in settings to clear local tracking data.
Users may also remove app data through Android system settings or by uninstalling the app, depending on Android device behavior.
Children’s privacy
HydroFast is intended for general wellness and habit tracking. It is not specifically designed for children.
TODO: Confirm the target age group selected in Google Play Console before publishing.
