1. What are cookies
Cookies are small text files that a website stores on your device. Some are essential for the site to work; others measure use or personalise content.
Cookies Policy
Zemmer only uses the cookies it needs to work. We do not use advertising cookies and we do not track you across other websites.

2. Cookies we use
These are strictly necessary, so they do not require your consent:
- Session cookie (authjs.session-token): keeps you logged in.
- Security cookies (authjs.csrf-token, authjs.callback-url): protect login and sign-up forms against forgery.
- Language cookie (NEXT_LOCALE): remembers which language you use the site in.
3. Third parties
The map on the rooms page loads its images from OpenStreetMap’s servers. They set no cookies, but like any website they receive your IP address and browser information; see osmfoundation.org/wiki/Privacy_Policy.
When you pay, Stripe may set its own cookies to process the payment and prevent fraud. We do not control them; see stripe.com/privacy.
4. Analytics and advertising
Today we use no analytics or advertising cookies. If that changes, we will update this page and ask for your consent first.
5. Managing cookies
You can delete or block cookies in your browser settings. Blocking the essential ones means you will not be able to log in. Questions: contact@zemmer.lu.
