This Privacy Policy describes how SPO2 Watcher ("we," "our," or "the App") handles your data. We are committed to ensuring your health data remains private, secure, and under your total control.

1. WE DO NOT COLLECT YOUR DATA SPO2 Watcher is a "no-server" application. We do not collect, store, or transmit any of your personal or health information to any external server, database, or third party. All processing happens locally on your device.

2. HEALTHKIT INTEGRATION The App requests permission to read "Oxygen Saturation" data from the Apple Health app (HealthKit) to display it on your dashboard and Watch complications.

• Storage: This data is read directly from HealthKit and is never stored in any other location by our app.

• Usage: We use this data solely to provide you with visual charts, 24-hour trends, and real-time Watch face updates.

• Control: You can revoke the App’s access to HealthKit at any time via the iOS Health app (Settings > Health > Data Access & Devices).

3. THIRD-PARTY SHARING We do not share your health data with third parties. We do not use third-party analytics or advertising SDKs. Your health data will never be sold to data brokers or used for marketing purposes.

4. SECURITY Your data is protected by Apple’s system-level security. HealthKit data is encrypted on your device and is only accessible when your device is unlocked. If you use iCloud to sync Health data, it is protected by Apple's end-to-end encryption.
