This website is delivered through Cloudflare Pages and the Cloudflare network. The provider is Cloudflare, Inc., 101 Townsend Street, San Francisco, CA 94107, USA. Cloudflare processes connection and security data to provide the website, mitigate attacks, deliver content and improve availability.
Processing in countries outside the European Union or the European Economic Area, in particular in the United States, cannot be excluded.

Where Cloudflare processes personal data on our behalf, this is done on the basis of a data processing agreement.

If you contact us by email, we process the data you send, especially your email address, message content and technical transmission information. Processing is carried out to handle your request. The legal basis is Article 6(1)(f) GDPR; if your request concerns a contract or pre-contractual measures, Article 6(1)(b) GDPR also applies.
We keep this data only as long as necessary to handle the request and any follow-up questions, or as required by statutory retention duties.
