We use cookies and other web technologies on our website to make your visit attractive and to enable the use of certain functions. Many useful functions on our website cannot be implemented without the use of cookies.

A cookie is a small file that stores Internet settings. It is loaded from the Internet browser the first time you visit a website. The next time you visit this website, the cookie and the information stored therein will either be transmitted to the website that generated it (first party cookie) or to another website to which it belongs (third party cookie). Thus the website recognizes that it has already been visited with this browser. Other web technologies are used for similar purposes, so that we also refer to these technologies as "cookies" in this context.

Most of the cookies we use are deleted from your hard disk at the end of the browser session (so-called session cookies). Other cookies remain on your computer and enable us to recognize your computer upon your next visit (so-called permanent cookies).


Depending on their function and intended use, cookies can be divided into four categories: cookies required for operation, performance cookies, functional cookies or cookies for marketing purposes:

  • Cookies required for operation are needed so that you can navigate on our website and use the basic functions of the website, such as assignment of anonymous session IDs.
  • Performance cookies are used to improve the user-friendliness of a website. They collect information about the use of our website, e.g. information about the Internet browser and the operating system; the domain name of the website from which you came, number of visits, average length of stay, pages accessed. However, these cookies do not store any information that allows for personal identification of the user.
  • Functional cookies enable a website to store information already provided (such as user name, language selection or your location) and to offer the user improved, more personalized functions. Functional cookies are also used to enable requested functions such as video playback.
  • Cookies for marketing purposes are used to offer relevant, adapted content to the user. They are also used to limit the frequency of an ad and to measure and control the effectiveness of advertising campaigns. They register whether or not a website has been visited and what content has been used. This information may be shared with third parties, e.g. advertising partners.

Most Internet browsers allow you to manage the use of cookies, e.g. to accept or reject all cookies or to accept only certain cookies. You can also set your browser to inform you when cookies are placed. This makes the use of cookies transparent for you. You will find the options for managing and deleting cookies in the documentation included in the respective browser.

If cookies are deactivated for our website, then it may no longer be possible to use all of the functions of the website in full.


If you do not deactivate cookies in your browser and use our website, then you agree to the use of cookies for the marketing purposes described here. You can revoke this consent at any time with effect for the future, e.g. by refusing the acceptance of cookies in your browser settings. The legal basis is provided by Article 6 Clause 1 lit. a) of the EU General Data Protection Regulation [GDPR].
