1.1. Health Data (Apple HealthKit)
If you grant permission, the App may read the following data:

Your HealthKit data never leaves your device.
It is not stored on our servers and is never shared with third parties.

If you grant permission, the App may read:
- total time spent on device,
- total usage across categories (e.g., entertainment, productivity).
We do not read information about specific apps you use.
Screen Time data is used to:
- estimate how much focus you may have consumed,
- improve your daily focus predictions,
- personalize recommendations.
All data stays on your device.
1.3. App Usage Data
We may collect minimal anonymized analytics (e.g., crash data, general engagement) to improve app performance.
This data cannot identify you personally.
