a) DNS and Content Delivery Network (Cloudflare)
We use the DNS service and global Content Delivery Network provided by Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA. Traffic between your browser and our web server is routed through Cloudflare's global network (reverse proxy).

Processing is based on our legitimate interest in the security, stability, and high-performance provision of our online offering pursuant to Art. 6 Abs. 1 lit. f GDPR. A Data Processing Addendum based on EU Standard Contractual Clauses has been concluded with Cloudflare; Cloudflare is also certified under the EU-U.S. Data Privacy Framework.

Consent pursuant to § 25 Abs. 1 German Telecommunications-Telemedia Data Protection Act (TDDDG) is therefore not required.

Legal basis: Processing is based on our legitimate interest in anonymous, data-minimalist reach analysis and technical optimization of our offering pursuant to Art. 6 Abs. 1 lit. f GDPR.
