7. Cookies & Analytics

We use a single session cookie (session_token) to keep you logged in. No advertising or third-party tracking cookies are used.

This website uses Matomo (self-hosted at matomo.bitlink.gmbh) for anonymised web analytics. Matomo is operated in cookieless mode — no cookies are set and no personal data is stored. Only anonymised usage data (page views, referrers, approximate region) is collected to help us improve the service. This processing is based on our legitimate interest (Art. 6(1)(f) GDPR) and does not require your consent.
