1. What are cookies?

Cookies are small files that a website stores on your device. Some are needed for the site to work; others we only use with your consent. Sometimes we use your browser's local storage; the same rules apply to it.

5. Statistics without cookies

For general visitor numbers we use Plausible, on our own server. Plausible sets no cookies, stores no IP addresses and does not track you across other websites. No consent is needed for it.

You can change or withdraw your choice at any time via "Cookie settings" at the bottom of every page. If you withdraw your consent, we delete the cookies concerned. You can also delete or block cookies in your browser settings.
