2 · Hosting — Cloudflare Pages

This website is hosted via Cloudflare Pages (Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA). When you visit this site, Cloudflare's servers automatically collect and temporarily store standard server log data, including:

IP address of the requesting device
Date and time of the request
URL requested
HTTP status code and bytes transferred
Browser and operating system (User-Agent string)
Referring URL (if any)

This data is processed by Cloudflare to deliver the website, protect against abuse, and maintain service reliability. We do not receive or store individual server logs. Cloudflare retains log data according to their own retention policy.

Legal basis: Art. 6 (1)(f) GDPR — legitimate interest in operating a technically stable and secure website.
Third-country transfer: Cloudflare may process data on servers outside the EU/EEA. This transfer is safeguarded by the EU–US Data Privacy Framework and Standard Contractual Clauses (SCCs). See Cloudflare's privacy policy: cloudflare.com/privacypolicy.
