Privacy Policy
Last updated: June 25, 2025
What we collect
Anonymous session data. On first visit we create an anonymous Supabase Auth session so you can play without signing up. This session is stored in your browser's local storage.
Game data. Your chosen display name, avatar seed, answers, and guesses are stored in our database for the duration of a game session and then retained for game history.
Account data (optional). If you sign in with Google or email, we store your name and email address via Supabase Auth to persist your identity across sessions.
Payment data. If you subscribe to Premium, payments are processed by Stripe. We only store your Stripe customer ID and subscription status — we never see or store your card details.
Usage analytics. We may use anonymous, aggregated analytics (page views, feature usage) to improve the game. No personally identifiable information is included.
Advertising. If enabled, Google AdSense may set cookies and collect data to serve personalized ads. See Google's privacy policy for details.
How we use it
- To run the game and synchronize state between players in real time
- To authenticate you and remember your preferences
- To process and manage Premium subscriptions
- To improve the game based on aggregated usage patterns
