Privacy Policy

Last updated: December 2025

Smile Battle ("we", "our", or "us") operates the Smile Battle mobile application (the "App"). This Privacy Policy explains how we collect, use, and protect your information when you use our App.

1. Information We Collect

Camera Data

Smile Battle uses your device camera exclusively for real-time face detection and gameplay purposes. Camera frames are processed on-device only and are never recorded, stored, or transmitted to our servers.

Face Data

Face detection is performed locally on your device using on-device machine learning. We do not collect, store, share, or upload any biometric or facial data.

Gameplay Data

We may collect basic gameplay-related data such as scores, game actions, coin balances, and room identifiers to enable multiplayer functionality and gameplay synchronization. This data does not include personal or biometric information.

Personal Information

Smile Battle does not require real names, email addresses, phone numbers, or contact lists. Usernames are chosen freely by the user and are not required to identify real individuals.

2. How We Use Information

Information collected is used solely to:

3. Data Sharing

We do not sell, trade, or share your personal information with third parties. No camera images, video streams, or face data are shared with external services.

4. In-App Purchases

Smile Battle offers optional in-app purchases for virtual coins. All purchases are processed securely through Google Play Billing. We do not collect or store payment or credit card information.

5. Children’s Privacy

Smile Battle is not intended for children under the age of 13. We do not knowingly collect personal information from children. If you believe that a child has provided us with personal data, please contact us and we will remove it promptly.

6. Data Security

We take reasonable measures to protect game-related data. On-device processing ensures that sensitive camera and face data never leave your device.

7. Your Rights

You may stop using the App at any time. Because we do not store personal or biometric data, there is no personal data to access, modify, or delete.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
