HabitHash has no developer account, analytics or advertising SDK. The developer does not receive your habits, completion records or reminder settings through the app.
Habit details, completion history, schedules and preferences are stored locally using the app's UserDefaults storage. Heatmaps and insights are computed on the device. Optional reminders use local system notifications and require notification permission. The app does not provide cross-device sync.
Removing the app can remove local records. Device backup and restoration are controlled by your system settings and backup provider.
StoreKit provides product information, purchases, restoration and verified entitlement checks. These services may communicate with Apple and need a network connection. HabitHash uses entitlement information to unlock Pro and does not receive payment card details. Apple's privacy policy applies to its services.
External links you choose to open are handled by the destination service. If you contact support, the developer receives what you send; avoid sharing private habit records unless needed to explain a problem.
