Privacy Policy

Last updated: 2026-04-08

What we collect

When you create an account we store your email address and a hashed password. We also store your solve times and algorithm selections so they sync across devices.

If you use the app without signing up, solve data is kept in your browser's local storage and never sent to our servers.

How we use your data

Your data is used solely to provide the SpeedcubeQuest service — displaying your solves, tracking progress, and syncing preferences. We do not sell, share, or use your data for advertising.

Cookies

We use a small number of cookies for authentication (keeping you signed in). We do not use tracking or advertising cookies.

Third-party services

• Supabase — hosts our database and handles authentication. Supabase Privacy Policy
• Vercel — hosts the application. Vercel Privacy Policy
• Sentry — error tracking and performance monitoring. When an error occurs, Sentry receives technical details such as the error message, stack trace, browser/OS info, and page URL. Sentry may also record anonymised session replays to help us reproduce issues. No personal data (email, solve times) is intentionally sent to Sentry. Sentry Privacy Policy

Data deletion

You can delete your account and all associated data at any time from the Account page, or by contacting us.
