Privacy Policy

Last Updated: December 25, 2025

Caffeine Curfew ("the App") respects your privacy. We believe your health data belongs to you, and only you.

1. HealthKit Data

The App integrates with Apple's HealthKit to read and write caffeine data.

• Read: We read caffeine history to calculate your current energy levels and sleep curfew.
• Write: When you log a drink, we save it to HealthKit so your data is available in Apple Health.
• No Sale of Data: We DO NOT sell, rent, or share your HealthKit data with third parties or advertisers.

2. Data Storage

All metabolic calculations happen locally on your device. Your data is stored in:

• The local database on your iPhone/Watch.
• Apple Health (if permissions granted).
• Your personal iCloud (if you have iCloud Backups enabled).

We do not operate external servers that hold your personal health data.

3. Analytics

We do not track your location or personal identity. We may collect anonymous, aggregate usage data (e.g., "Crash rates") provided by Apple to help us improve app stability.

4. Contact
