General data

With every access to this website the webspace provider automatically saves the following information in a server logfile: name of website, date, size of data, web browser, operating system, IP address, referring website and status information of the webserver. This data is of general nature, does not directly refer to a specific person and is technically required to operate the webserver. The data can be statistically analysed to improve the presentation of the website and will be used in case of illegal activities of our website. Data that was acquired before the 1st day of the previous month will be automatically deleted


The website does not use “cookies” to store user preferences, but this does not apply to linked other websites and services. Cookies are files that are created by the webserver and are stored on the computer of the user. They can identify the connection between webserver and user (session cookie) and improve the functionality of the website e.g. by storing the language selection and the agreement to cookies permanently.  Our websites and services do not use this information for other purposes and do not pass it to a 3rd party (no user tracking). Many web browsers accept cookies by default. The user should use the help system available for the webbrowser to learn how the cookie settings can be modified.

Services and content of 3rd parties

Our website occasionally uses content and services of other providers that will subsequently be called “3rd parties”, e.g. Google-Maps as well as graphics and images of other websites. On access the user will pass at least the General Data listed above to the 3rd party. Because we have no control over the privacy policy of the 3rd party we have tagged this content so the user keeps control over the transfer of his data.


To protect the web content during transfer between user and webserver from 3rd parties they are provided by HTTPS using state of the art encryption technology
