Necessary Cookies are essential for the operation and the functions of our website and can therefore not be disabled. They especially allow for secure operation and serve to save input of users, e.g. the display language, which consequently does not have to be set for each individual request. The information saved in these cookies is exclusively used by us (first-party cookies). Necessary cookies can be blocked or deleted via browser settings but this may impact the functionality of the website.

With the help of statistics cookies, we collect information on how our website is used. We measure which contents are viewed more often or less frequently, when and from where (e.g. time and country) page views occur and we can count the visits to our website. The information is anonymized by aggregation and analysed statistically in pooled groups. On the basis of this analysis the popularity of contents is evaluated and the functionality of our website is optimized. If you disable these cookies, we can no longer determine whether our website has been visited from your device before. For further information on the analysis service used please see our Privacy Policy.

Marketing cookies are set by external service providers (third-party cookies) and are used for advertising purposes when the contents of our partners are viewed. The external service providers collect information across websites about the contents viewed by the users. Marketing cookies are often based on uniquely identifying your browser or device. The collected data is used for targeted advertising, to create user profiles and to display contents corresponding to potential interests. In the case of a cross-border data transfer to a country outside the EU/EEC, there may be a lower level of data protection and the risk of secret access by the authorities (e.g. USA). If you disable these cookies, contents of external service providers will be blocked.
