Cookie policy

This page explains which cookies and storage entries we use, which of them are only set with your consent, and how you can change your decision at any time.

Technically necessary storage

We store one entry in your browser’s local storage (localStorage) under the key consent-v1. It remembers your consent decision so that we do not have to ask you again on every visit. This entry is technically necessary and requires no consent.

Analytics cookies — only with your consent

Only if you choose "Accept all" in the consent banner are the following cookies set:

_ga, _ga_* — Google Analytics 4, distinguishes visitors, lifetime up to 2 years
_clck — Microsoft Clarity, visitor id, lifetime 1 year
_clsk — Microsoft Clarity, session id, lifetime 1 day

If you choose "Only necessary", none of these cookies are set. Details on the services can be found in our privacy policy.

Changing or withdrawing your consent

You can change your decision at any time via the "Cookie settings" link in the footer. If you switch from "Accept all" to "Only necessary", analytics cookies that have already been set are removed and no further data is collected (withdrawal with effect for the future, Art. 7(3) GDPR).

Deleting browser storage

You can delete cookies and local storage at any time via your browser settings (e.g. Chrome: Settings → Privacy and security → Clear browsing data; Firefox: Settings → Privacy & Security → Cookies and Site Data; Safari: Settings → Privacy → Manage Website Data). You will then be asked again on your next visit.
