Data Deletion
Users can delete data through the following methods:

- Stop analytics: Turn off "Share Usage Data" in settings
Children's Privacy
The App is not directed at any specific age group and does not intentionally collect personal information from children under 13.
Security
App data is stored on the device and protected by device security features (passcode, Face ID, Touch ID, etc.). The App itself does not have password protection features. Opt-in analytics data is transmitted encrypted via HTTPS.
About Accounts
