Cookie Policy
1. What Are Cookies?
Cookies are small text files that are stored on your device (computer, tablet, smartphone) by websites. They serve to make websites functional, improve their efficiency, or provide information to the website operator.
2. Which Cookies Do We Use?
Our website uses exclusively technically necessary cookies. We do not use tracking cookies, advertising cookies, or third-party cookies.

3. Third-Party Cookies
We do not use third-party cookies:
- Web Analytics: We use Umami, open-source web analytics software. We do not use a cloud service: the software is operated on our own server in the EU on our behalf (
analytics.worqable.com). No data is transmitted to the maker of Umami. Umami sets no cookies and stores no IP addresses. For details, see our Privacy Policy. - Fonts: All fonts are served locally from our own server (self-hosting). No connection to external servers (e.g., Google Fonts) takes place.
- Social Media: We do not embed social media plugins or trackers.
4. Legal Basis
The use of technically necessary cookies is based on § 25 para. 2 no. 2 TDDDG (German Telecommunications Digital Services Data Protection Act). These cookies are strictly necessary for the operation of the website and do not require consent.
Since we exclusively use technically necessary cookies, no cookie consent banner is required.
5. Managing Cookies
You can manage or delete cookies at any time in your browser settings. Please note that disabling technically necessary cookies may restrict the functionality of the website (e.g., client portal login, language settings).
