When you access the website, information of a general nature is automatically collected. This information (server log files) includes, for example, the type of web browser, the operating system used, the domain name of your Internet service provider, the IP address, the time stamp of access to the website and similar. This is exclusively information that does not allow any conclusions to be drawn about your person. This information is technically necessary in order to correctly deliver the website content requested by you and is mandatory when using the Internet. Anonymous information of this kind is statistically evaluated by us in order to optimize our website and the technology behind it. The retention period for aggregated and anonymized statistics is 12 months. The data is stored exclusively for security, statistical and technical reasons, for example to detect faults.

For this purpose, the usage information generated by the cookie (including your shortened IP address) is transmitted to our server and stored for usage analysis purposes, which serves to optimize our website.
