Privacy Policy

What we store

Fermiq stores your practice history, Elo rating, question preferences, and settings in your browser's localStorage. This data never leaves your device. There is no user account, no login, and no server-side storage of your personal data.

What we don't store

• Your name, email, or any personal identifier
• Your IP address or location
• Cookies beyond what the PWA framework requires
• Any analytics or tracking data

Third-party services

Fermiq is served from Railway. Railway's infrastructure may log standard HTTP request metadata (IP, user agent) for security purposes. We do not use any advertising networks, social login services, or analytics platforms.

Deleting your data

Go to /stats and use the “Clear history” button. This removes all locally stored practice data. Since nothing is stored on our servers, there is nothing else to delete.
