Privacy Policy

Last updated: February 6, 2026

GroupPlay ("we," "us," or "our") operates the GroupPlay web application. This Privacy Policy explains how we collect, use, and protect your information.

Information We Collect

Session Information: When you join a game room, you provide a display name. This is stored temporarily in your browser's localStorage and shared with other players in your room. No account is required.

Game Data: During gameplay, your moves and game state are transmitted between players to enable real-time multiplayer. This data is stored temporarily on our servers and deleted when the room expires.

Usage Data: We may collect basic usage information such as pages visited and device type to improve the service.

How We Use Your Information

We use your information to:

  • Enable real-time multiplayer gameplay between you and other players in your room
  • Maintain your session if you disconnect and reconnect
  • Maintain and improve the service

We do NOT:

  • Sell your personal data to third parties
  • Require accounts, emails, or passwords
  • Use your data for advertising or marketing purposes
  • Track you across other websites

Data Storage and Security

Your display name and session data are stored locally in your browser. Game state is stored temporarily on secure servers (Supabase) and automatically deleted after 24 hours of room inactivity. We implement reasonable security measures to protect your information, but no method of transmission or storage is 100% secure.

Your Rights

You can:

  • Leave any game room at any time
  • Clear your browser's localStorage to remove all local session data
  • Use the service without providing any personal information beyond a display name

Cookies

We use essential browser storage only (localStorage for session management). We do not use tracking cookies or third-party analytics cookies.

Third-Party Services

GroupPlay uses Supabase for real-time database functionality. See Supabase's Privacy Policy for details on their data practices.

Children's Privacy

This service is not intended for anyone under the age of 13. We do not knowingly collect information from children under 13.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by posting the new policy on this page with an updated date.
