We take the protection of your personal data seriously and process it exclusively on the basis of the applicable data protection legislation, in particular the General Data Protection Regulation (GDPR) and the German Federal Data Protection Act (BDSG). Personal data is collected and processed only to the extent necessary to fulfil the relevant purpose.

This website is hosted on servers operated by Netcup GmbH, Daimlerstraße 25, 76185 Karlsruhe, Germany. The server infrastructure is located exclusively in Germany. We have concluded a data processing agreement with Netcup in accordance with Article 28 GDPR. No transfer of your data to countries outside the European Union takes place in connection with the hosting of this website.
The legal basis is Article 6(1)(f) GDPR. Our legitimate interest lies in the reliable and secure operation of this website.

Each time our website is accessed, our hosting provider automatically records information in server log files. The following data is collected: the IP address of the requesting device, the date and time of access, the name and URL of the file retrieved, the HTTP status code, the volume of data transferred, the website from which access originated (referrer URL), and information about the browser, operating system, and internet provider.
This data is processed solely for the purpose of technically delivering the website and for detecting and defending against attacks, and is not merged with any other data sources. The legal basis is Article 6(1)(f) GDPR.
