Privacy Policy

What we collect

If you create an account we store the email address you provide and your learning progress (plan, lessons read, practice attempts, scores, XP, and streak). Guest mode stores nothing on our servers; a guest session is a short-lived signed cookie that expires after 24 hours.

How we use it

Only to run the learning app: to save your progress, grade assessments on the server, and show your readiness. We do not sell your data or use it for third-party advertising.

Your rights

You can export or erase your learning data at any time via Tools → Export/Erase Personal Data, or by contacting us. Deleting your account removes your progress and attempts.

Email verification

We confirm your email address with a one-time link to prevent misuse. Verification tokens are stored hashed and expire automatically.
