Privacy Policy

Last updated: March 16, 2026

Human Body Explorer ("we", "our", "the app") is an educational anatomy game developed by an independent developer. Your privacy is important to us. This policy explains what data we collect and how we use it.

1. Data We Collect

Account data: When you create an account, we store a username and hashed password. No email address is required.

Game progress: Your XP, level, completed lessons, challenge attempts, achievements, and PvP history are stored on our server to enable cross-session progress.

Settings: Your language preference and display settings are stored with your account.

2. Data We Do NOT Collect

• No email addresses, real names, or personal identification
• No location data or GPS
• No contacts, photos, or device files
• No advertising identifiers or tracking pixels
• No third-party analytics (no Google Analytics, no Firebase Analytics)
• No cookies for tracking purposes

3. How We Use Your Data

Your data is used solely to:

• Save and restore your game progress
• Display leaderboards and PvP rankings
• Enable multiplayer features (PvP, Co-op)

4. Data Storage & Security

All data is stored on a secure server (Google Cloud Platform, EU region). Passwords are hashed using industry-standard algorithms. Communication uses HTTPS encryption.

5. Third-Party Services

The app may use RevenueCat for in-app purchase management. RevenueCat processes payment data according to their own privacy policy. We do not have access to your payment details (credit card numbers, etc.).

6. Children's Privacy

Human Body Explorer is an educational app suitable for all ages. We do not knowingly collect personal information from children under 13. The app does not require any personal information to function — only a username of your choice.
