HabitTracker ("the App") is developed by Alan Zhang. This privacy policy explains how the App handles your data.
HabitTracker does not collect, store, or transmit any personal data to external servers. All your habit data, completion history, and settings are stored locally on your device using Apple's SwiftData framework.
Your data is stored exclusively on your device and in your device's local app container. If you use the home screen widget, data is shared between the app and widget via an App Group container — this stays entirely on your device.
The App does not use any third-party analytics, advertising, or tracking services.
The App may send local notifications as habit reminders if you enable them. These are scheduled entirely on your device and do not involve any external servers.
Deleting the App from your device removes all associated data. You can also delete individual habits and their history from within the App.
The App does not knowingly collect any data from children or any other users.
If this policy changes, the updated version will be posted at this URL.
