1. What Cookies Are

Small text files stored on your device by a website, together with similar technologies such as browser local storage.

2. What This Site Does Not Use

This website uses no analytics, advertising, profiling, heatmap or session-recording technologies. There is no Google Analytics, no Microsoft Clarity and no session replay. Nothing on this site tracks you across other websites.

3. What May Be Set

Strictly necessary cookies set by Cloudflare, the hosting and security provider, to distinguish automated traffic from human visitors and to keep the site available. These cannot be switched off without preventing the site from working. On the contact page only, the Cloudflare Turnstile check may store a short-lived token in your browser while you complete the form, used solely to confirm that the submission is not automated.

4. Consent

Because no analytics, advertising or tracking technologies are in use, this site shows no consent banner. If that ever changes, a consent mechanism will be introduced before any such technology is loaded, and this page will be updated first.

5. Managing Cookies

You can block or delete cookies through your browser settings. Blocking strictly necessary cookies may prevent parts of this site from working.

6. International Transfers

Cloudflare operates a global network, so strictly necessary processing may take place outside Switzerland and the EEA, under Standard Contractual Clauses or an equivalent safeguard.

7. Contact

8. Language Versions

This policy is also published in German and French. In the event of any discrepancy between the language versions, the English version governs.
