Information on data processing

Your data processed when using our website will be deleted or blocked as soon as the purpose of the storage no longer applies, the deletion of the data does not conflict with any statutory retention obligations and no other information is provided below on individual processing procedures.

Server data

For technical reasons, in particular to ensure a secure and stable Internet presence, data is transmitted to us or to our web space provider via your Internet browser. With these so-called server log files, the type and version of your Internet browser, the operating system, the website from which you have switched to our Internet presence (referrer URL), the website(s) of our Internet presence that you visit, the date and time of the respective access and the IP address of the Internet connection from which the use of our Internet presence takes place are collected, among other things.

The data collected in this way is stored temporarily, but not together with other data about you.

This storage takes place on the legal basis of Art. 6(1)(f) GDPR. Our legitimate interest lies in the improvement, stability, functionality and security of our website.

The data will be deleted after seven days at the latest, unless further storage is required for evidence purposes. Otherwise, the data shall be exempt from deletion in whole or in part until the incident has been finally clarified.


a) Session cookies

We use so-called cookies on our website. Cookies are small text files or other storage technologies that are placed and stored on your end device by the Internet browser you use. These cookies process certain information from you, such as your browser or location data or your IP address, to an individual extent.

This processing makes our website more user-friendly, effective and secure, as the processing enables, for example, the reproduction of our website in different languages or the offer of a shopping basket function.

The legal basis for this processing is Art. 6(1)(b.) GDPR, insofar as these cookies process data for contract initiation or contract fulfilment.

If the processing does not serve to initiate or fulfil a contract, our legitimate interest lies in improving the functionality of our website. The legal basis is then Art. 6(1)(f) GDPR.

These session cookies are deleted when you close your Internet browser.

b) Third-party cookies

Our website may also use cookies from partner companies with whom we cooperate for the purposes of advertising, analysis or the functionalities of our website.

Please refer to the following information for details, in particular the purposes and legal basis for processing such third-party cookies.

You can prevent or restrict the installation of cookies by changing the settings in your Internet browser. You can also delete cookies that have already been saved at any time. However, the steps and measures required for this depend on the specific Internet browser you are using. If you have any questions, please use the help function or documentation of your Internet browser or contact its manufacturer or support. In the case of so-called Flash cookies, however, processing cannot be prevented via the browser settings. Instead, you must change the settings of your Flash player. The steps and measures required for this also depend on the specific Flash Player you are using. If you have any questions, please also use the help function or documentation of your Flash Player or contact the manufacturer or user support.

However, if you prevent or restrict the installation of cookies, this may mean that not all functions of our website can be used to their full extent.

Security information

We secure our website and other IT systems against loss, destruction, unauthorised access, unauthorised modification or unauthorised distribution of your data by means of suitable technical and organisational measures.
