3. Hosting and server log files
This website is hosted on a server operated by STRATO GmbH, Otto-Ostrowski-Straße 7, 10249 Berlin (referred to below as “Strato”). When you access the website, the server automatically processes information transmitted by your browser in server log files. This may include:

Processing is carried out on the basis of Article 6(1)(f) GDPR. The legitimate interest lies in the technical provision, stability and security of the website, in particular the prevention of attacks and the analysis of errors.
