Privacy

Last updated: 5 October 2026

Rehbar AI runs this free course. We collect as little as we can, and we never sell your data or use it for advertising.

If you just read the course

We count visits with Umami, a privacy-friendly analytics tool. It does not use cookies and does not store your IP address. We see totals such as which pages were read, which country visitors come from, and what kind of device they use, but never who you are.

Your progress and your light or dark mode choice are saved in your own browser. They never leave your device unless you log in.

If you log in

Logging in is optional and only used to keep your progress across devices. We store:

• your email address, to send you a login link;
• when you signed up and last logged in;
• which chapters you marked as complete, and when;
• if you ask for a certificate, the name you type for it. Anyone who has your certificate's link can see that name, the course and the date, so they can check the certificate is real.

This data is kept by Supabase, our database provider, in the EU region. Login emails are sent through our email provider. We never email you anything except the login links you ask for.

Deleting your data

Email [email protected] from the address you log in with, and we will delete your account, progress and certificate within 30 days. You can also clear progress on this device any time by clearing this site's data in your browser.
