Categories of cookies

We use cookies for a variety of purposes and with different functions. Moreover, we make distinctions between cookies, depending on whether they are mandatory from a technical perspective (i.e. a technical requirement), how long they are stored and used (known as the retention period) and whether they have been set by our website itself or by a third party and, if so, by whom (i.e. by which cookie provider).

Technical requirement and legal basis

Technically mandatory cookies: We use certain cookies because they are mandatory requirements to ensure that our website and its functions can work in a legally compliant manner. Such cookies are automatically set when the website or a specific function is accessed, unless you have prevented the setting of cookies through your browser settings. Any data collected through the use of such cookies are processed by us on the basis of GDPR Article 6 (1) point f.

Technically non-mandatory cookies: On the other hand, non-mandatory cookies are set to improve, for instance, the convenience and performance of our website or to save certain settings you have made. We also use technically non-mandatory cookies to obtain information on the frequency with which certain parts of our website are used, so that we can tailor them more closely to your needs in the future. We do not store technically non-mandatory cookies until you click the relevant box, confirming that you have read our cookie note, and continue to use our website. Any data collected through the use of such cookies is processed by us on the basis of GDPR Article 6 (1) point a.

Retention period

Session cookies: Most cookies are only required for as long as you access the current service or continue your session. They are either erased or lose their validity as soon as you leave our website or your current session has expired (these are so-called session cookies). Session cookies are used, for instance, to retain certain information during your session.

Permanent cookies: It happens occasionally that cookies are saved for a longer period of time, for instance, to recognise you when you open our website again at a later point. It means that you can call up saved settings again. This means you can access our website faster and more conveniently, and you don’t have to make certain settings again, e.g. specify the relevant language. Permanent cookies are automatically deleted upon the expiry of a defined period of time following the date on which you visited the site or domain where the cookie was set.

Cookie providers

Third-party cookies: So-called third-party cookies are set and used by other providers or websites, for example by operators of web analysis tools. Further details on web analysis tools and range measurement can be found below in this Policy. Third-party providers can also use cookies to display adverts or to integrate social media content, e.g. social plug-ins.

Erasure of and objection to the use of cookies

If you do not want cookies to be saved to your device, you can disable the relevant option in the system settings of your browser. Saved cookies can be deleted through the system settings in your browser at any time. Please note, however, that if you do not accept cookies, the functions of our services may be limited.
