Privacy Policy

Effective February 19, 2026

1. What we collect

We collect only what is necessary to run the service:

  • Guest players — no account required. Your game sessions and progress are stored only in your browser's local storage. We also record an anonymous event log (game slug, score, difficulty, time) on our servers with no personally identifiable information attached.
  • Signed-in users — when you create an account we store your email address, game session history, streaks, and achievements in our database (Supabase / PostgreSQL, hosted on AWS).
  • Google OAuth — if you sign in with Google we receive your email address and profile picture URL from Google. We do not receive your Google password.
  • Contact messages — if you submit a message through the contact form we store your email and message text.

2. How we use your data

  • To display your personal dashboard, streaks, and achievement history.
  • To aggregate anonymous play statistics so we can improve the game library.
  • To respond to contact form submissions.

We do not sell, rent, or share your personal data with third parties for marketing purposes.

3. Third-party services

4. Cookies & local storage

We use browser local storage to persist guest-mode progress. Supabase Auth sets an HTTP-only session cookie for signed-in users. We do not use advertising or tracking cookies.

5. Data retention & deletion

Guest data lives only in your browser and is cleared when you clear your browser storage. For signed-in accounts, contact us to request deletion of your account and all associated data.

6. Children's privacy

MathMathMath is intended for general audiences. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

7. Changes to this policy

We may update this policy from time to time. The effective date at the top of this page will reflect the most recent revision. Continued use of MathMathMath after changes constitutes acceptance of the updated policy.
