Privacy Policy

Effective date: July 19, 2026

This Privacy Policy describes how DuoDuel ("the App", "we") handles information when you use our mobile application.

1. Summary

DuoDuel does not require an account and does not collect or store personal information.

2. Information We Handle

No account data. The App has no sign-up or login. We do not collect your name, email address, phone number, or any other personal identifiers.
On-device data only. Game settings (sound, haptics), coins, and skins are stored only on your device and are never uploaded to our servers. Deleting the App removes this data.
Online matches. When you use the online mode, a temporary 4-digit room code and in-game signals (such as moves) pass through our relay server in real time. This data contains no personal identifiers, is not logged, and is deleted from server memory when the match ends or after a short idle period.

3. Advertising & Analytics

The App currently contains no advertising and no third-party analytics. If advertising (e.g., Google AdMob) is introduced in a future update, this policy will be updated in advance to describe the ad provider, the use of advertising identifiers, and available opt-out choices, and the change will be announced in the App.

4. Children's Privacy

The App does not collect personal information from anyone, including children. We do not knowingly process any data subject to COPPA (US), GDPR-K (EU), or similar children's privacy regulations.

5. Data Retention & Deletion

We retain no personal data on our servers, so there is nothing to request deletion of. All local data is removed when you uninstall the App.

6. Security

Online match traffic is limited to anonymous game signals. We apply reasonable measures to keep the relay server secure and stateless.

7. Changes to This Policy

If this policy changes, the updated version will be posted on this page with a new effective date, and material changes will be announced in the App.
