Purchases & Restoring

All in-app purchases go through the App Store — payments, billing and refunds are handled by Apple.
After switching devices or reinstalling the app, open Settings → Restore Purchases with the same Apple ID to get your Pro benefits back.

Manage it on iPhone / iPad under Settings → [your name] → Subscriptions, or open the App Store subscriptions page.
After canceling, Pro stays available until the end of the current period; after that you only lose features — none of your data is ever deleted.

Turn it on in the app's Settings; data syncs to your own private iCloud database, which nobody else — including the developer — can read.
Sign in with the same Apple ID on a new device, turn sync on, and your data picks up automatically.

The app offers full-library export / import. You keep the backup file yourself and can restore it on another device anytime.

Once you grant permission, Health features only read the specific data types you choose. They stay on this device only, never enter iCloud, and are never used for anything else.
You can revoke access anytime in system Settings → Health.

This version does not currently offer AI features. The AI assistant and API key configuration are unavailable, including for Pro users.
This version does not initiate AI service or model-directory requests. Hiding AI entry points does not delete conversations, configurations or Keychain keys saved by older versions.
Older versions may still use their original AI services. Disabling AI in this version does not mean those services have stopped or historical records have been deleted.
See section 5 of the Privacy Policy for data processing and records from older versions.
