Cookies are stored on your computer when you use our website. You can download a detailed overview of the cookies we use and their storage periods below on this page. In addition, we provide answers below to the most frequently asked questions regarding cookies.

1. What are cookies?

Cookies are small text files that are assigned to and stored on your hard drive by the browser you use and through which certain information flows to the entity that sets the cookie (here by us). Cook-ies cannot execute programs or transmit viruses to your computer. They are used to make Internet services more user-friendly and effective as a whole.

2. What types of cookies are used?

This website uses the following types of cookies, the scope and function of which are explained be-low:

  • Session cookies

  • Persistent cookies

Session cookies store a session ID which is used to assign various requests from your browser to the shared session. The session cookies are deleted when you log out or close the browser. If you start your browser again and return to the website, it will not recognize you.

You have to log in once more (if logging in is necessary) or you have to set layouts and preferences again, if the website provides such functions. This will result in the generation of a new session cookie which will store your information and remain active until you leave the site again and close your browser.

Persistent cookies are automatically deleted after a predefined time period, which may vary according to the cookie. You can delete the cookies at any time using your browser’s security settings.

2) Performance (e.g. the user’s browser) and preferences

Description: Cookies are set when you use our website (e.g. to recognize the browser) in order to improve performance (e.g. quicker loading of content).
