Privacy Policy - Pain Diary

Last Updated: July 22, 2026

Pain Diary is developed by WittyApps. It is designed as a local-first diary for sensitive health information.

Information We Collect

• Pain entries, body areas, triggers, medication notes, custom trackers and settings are stored locally on your device.
• Subscription status is handled by RevenueCat and the App Store / Google Play so Pro features can be unlocked.
• Crash reports may be sent to Sentry if enabled in release builds.

We do not operate an account system and do not upload your diary entries to our servers. We do not sell data and do not use advertising.

Data Retention

Your diary data remains on your device until you delete entries, clear app data, or uninstall the app. A lapsed or cancelled subscription does not remove your entries. PDF files you generate are local files and remain accessible unless you delete them.

Security

The app includes optional app lock / biometric unlock. On Android, sensitive app-switcher screenshots are blocked. Device-level security remains important; use a device passcode and backups appropriate for your needs.

Third-Party Services

• RevenueCat: subscription entitlement management.
• Apple App Store / Google Play: payment processing.
• Sentry: crash reporting, if enabled.

Medical Disclaimer

Pain Diary is a self-tracking tool, not medical advice, diagnosis or treatment.
