## English Version

### Introduction

This Privacy Policy describes how "至诚转经轮" (Digital Prayer Wheel) ("we", "our", or "the App") collects, uses, and protects your information when you use our iOS, iPadOS, and watchOS applications.

### Information We Collect

**We do NOT collect any personal information.**

The App is designed with privacy in mind:
- **No user accounts required** - You can use all features without registration
- **No network connections** - The App works completely offline
- **No analytics or tracking** - We do not track your usage or behavior
- **No third-party services** - No external SDKs or services are integrated

### Data Storage

All data is stored **locally on your device only**:

1. **Prayer Counts**: Your prayer recitation counts are saved using iOS UserDefaults
2. **Settings**: Your preference settings (display mode, speed, opacity, etc.) are stored locally
3. **Daily Statistics**: Daily merit counts and consecutive days are stored on your device
4. **Background Calculation Data**: Timestamp and rotation speed for the intelligent catch-up system

**Apple Watch Data Sync**:
- If you use the Apple Watch version, data is synchronized between your iPhone and Apple Watch using Apple's Watch Connectivity framework
- This sync happens **only between your devices** - no data is sent to external servers

### Data We Do NOT Collect

We do NOT collect, store, or transmit:
- Personal identification information
- Location data
- Device identifiers
- Usage analytics
- Crash reports (unless you choose to share with Apple)
- Contact information
- Photos or camera access
- Microphone or audio data

### Data Sharing

**We do NOT share any data with third parties** because we don't collect any data in the first place.

Your prayer counts and settings remain **private and on your device**.

### Children's Privacy

The App is suitable for all ages (4+) and does not collect any personal information from anyone, including children under 13 years of age.

### Data Security

Since all data is stored locally on your device:
- Your data is protected by your device's security measures (passcode, Face ID, Touch ID)
- We recommend enabling device encryption and using a strong passcode
- Regular backups through iCloud or iTunes will include your prayer counts

### Your Rights

You have full control over your data:
- **Access**: View all your data within the App
- **Delete**: Uninstalling the App will remove all locally stored data
- **Export**: You can view statistics within the App (no export feature currently)
