Information we process

When you create an account, we process your email address and authentication records. When you complete practice while signed in, we store the submitted answer, module and question details, formative result, time used and repair status so your progress can be shown across devices.

Guest practice

If you do not sign in, recent score ranges and weakness summaries are stored only in your browser using local storage. Clearing browser data removes that local history.

Service providers

Supabase provides account authentication and database storage. Vercel hosts the website and may process technical logs such as IP address, browser type, requested page and error details for security and reliability.

Cookies

Signed-in accounts use essential authentication cookies. This version does not use advertising cookies or third-party advertising trackers.

Your choices and rights

You can clear module history from an assessment page. You may request access, correction or deletion of account information. Do not submit confidential, sensitive or personally identifying material in a practice answer.

Retention

Account attempts remain stored until you clear them or request account deletion. Hosting and security logs may be retained for a limited period by the relevant service provider.
