1. What are cookies?
Cookies are small text files that are stored on your device when you visit a website. They make it possible to recognise your device and to save preferences. The browser’s local storage works in a similar way. Cookies are distinguished by origin (first-party, third-party) and duration (session, persistent).
2. Categories used
- Necessary — security, sign-in and your cookie choice; always active, no consent required
- Analytics — Google Analytics 4, only after your consent
- Marketing — not currently in use
We also use Ahrefs Web Analytics: these statistics work without cookies and without recognising individual visitors and therefore do not require consent.

Marketing
We currently do not use any marketing or advertising cookies (e.g. Google Ads, Meta Pixel). The “Marketing” category in the cookie banner is reserved for possible future use — if it is activated, we will update this list beforehand.
4. Third parties & external content
- Cloudflare (USA) — security cookies and Turnstile spam protection on forms
- Google (Ireland/USA) — Analytics only after consent; without consent only cookieless signals without recognition (Consent Mode v2)
- YouTube (Google) — the video is only loaded when you click on it; from then on YouTube may set its own cookies. The preview image may be loaded from Google servers
- Google Maps — the map on the contact page is loaded by Google; Google may set cookies and receives your IP address

Transfers to the USA are based on the Swiss-U.S. Data Privacy Framework or on standard contractual clauses. Details in our Privacy Policy.
