2. Hosting
This website is hosted by Netlify, Inc., 512 2nd Street, San Francisco, CA 94107, USA. When you visit the site, Netlify processes technical data such as your IP address, browser type, and the time of your request in server access logs. This processing is necessary to deliver the website and to ensure its security and stability. Because Netlify operates from the USA, this data may be transferred outside Switzerland and the EEA.

This site currently shows no ads and loads no advertising scripts. If advertising is introduced in the future, this policy will be updated and your consent will be requested before any advertising cookies are set.
5. Legal basis
We process data in accordance with the Swiss Federal Act on Data Protection (FADP) and, where applicable to visitors from the EEA, the General Data Protection Regulation (GDPR). Technical hosting logs are processed based on our legitimate interest in operating a secure website (GDPR Art. 6(1)(f)).
6. External links
Listings link to gym websites, Instagram profiles, and Google Maps. Once you follow such a link, the privacy policy of the respective provider applies. We have no influence over their data processing.
