Visitors get no cookies
Reading this website, taking the free course and joining the waitlist set no cookies. There are no analytics, advertising or social media cookies. Visits are counted without cookies and without saving anything on your device; the privacy policy says how. Scripts are loaded only from this website’s own address. That is why there is no cookie banner.
The contrast switch
If you use the light and dark switch, your choice is saved in your browser’s local storage under the name “mc-theme”, so the page looks the same on your next visit. It holds only the word “light” or “dark”, stays on your device and is never sent to us. Saving a setting you asked for is allowed without consent under § 165(3) TKG 2021. Clearing the site data in your browser removes it.
Cookies after sign-in
Sign-in is for the operator of the engine and for customers the operator has given access. Signing in sets the cookies below. They are strictly necessary to sign in and to keep the session, and are therefore allowed without consent under § 165(3) TKG 2021.
| Cookie | Purpose | Lifetime |
|---|---|---|
| __Secure-better-auth.state | Ties the return from Google or GitHub to the sign-in you started there. | 5 minutes |
| __Secure-better-auth.session_token | Keeps you signed in. | Up to 12 hours |
| __Secure-better-auth.two_factor | Operator only: holds the sign-in between the password and the second factor. | 10 minutes |
| __Secure-better-auth.trust_device | Operator only: remembers a device that passed the second factor, when the operator chooses that. | 30 days |
All of them are first-party cookies set by this website, sent only over an encrypted connection and not readable by scripts.
Removing cookies
Signing out deletes the session cookie. You can also delete or block cookies in your browser settings at any time; the public website works without them.
