Privacy Policy

Last updated: March 8, 2026

Overview

Sketchmate ("we", "our", "the app") is a real-time multiplayer drawing party game. We are committed to protecting your privacy. This policy explains what data we collect and how we use it.

Data We Collect

• Player Name — The display name you enter when creating or joining a game. This is not linked to your identity and is only used within the game session.
• Drawings — Sketches you create during gameplay are sent to our server for AI judging. Drawings are processed in real-time and are not stored after the game session ends.
• Apple ID (optional) — If you choose to sign in with Apple, we receive your Apple ID token and, optionally, your name and email. This is used solely for authentication via Supabase Auth.

How We Use Your Data

• Gameplay — Player names and drawings are shared with other players in your game room during active sessions.
• AI Judging — Your drawings are analyzed by Cloudflare Workers AI (Llama 3.2 Vision) to generate scores and humorous verdicts. Drawings are not retained after processing.
• Authentication — Apple ID tokens are exchanged with Supabase for session management. We store a session token locally on your device.

Data Storage & Retention

• Game rooms are ephemeral and stored in Cloudflare Durable Objects. When a game ends, room data is deleted.
• We do not maintain a database of drawings, game history, or player profiles.
• Authentication tokens are stored locally on your device using UserDefaults and can be cleared by signing out.

Sketchmate is rated 4+ and does not knowingly collect personal information from children. The app does not require an account to play, and no persistent personal data is collected during anonymous gameplay.

Your Rights

You can sign out at any time to clear your local session data. Since we do not store personal data on our servers beyond active game sessions, there is no server-side data to delete.
