4. Analytics, tracking, and cookies

This website uses Cloudflare Web Analytics, a cookie-free analytics tool provided by the hosting provider Cloudflare (see section 3). Only aggregated usage data is collected (page views, referrer, browser, operating system, country). There is no individual visitor tracking or cross-site tracking. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in analyzing website usage). For more information, see Cloudflare's privacy policy.
