Cookie Policy


In order for this website to function properly, we sometimes place small files – so-called cookies – on your device. This is common for most major websites.

What are cookies?

A cookie is a small text file that a web portal leaves on your computer, tablet computer or smartphone when you visit it. It allows the portal to “remember” certain entries and settings (e.g. login, language, font size and other display preferences) over a period of time, so you don’t have to do this again each time you visit and navigate the portal.

How do we use cookies?

On our pages we use cookies to store

  • your screen display preferences, such as contrast and font size
  • your possible participation in a survey on the usefulness of the content (so that you will not be asked to answer again by a pop-up window)
  • Your decision to (or against) the use of cookies on this portal.

Some videos embedded on our sites also use cookies to compile anonymous statistics about the previously visited sites and the selected videos.

Accepting cookies is not absolutely necessary for using the portal, but it does make browsing more pleasant. You can block or delete cookies, but this may affect some functions of this site.

The information collected by cookies is not used to identify you and is entirely under our control. The cookies are not used for any other purpose than those mentioned here.

Control over cookies

You can control and/or delete cookies at will. You can find out how here: allaboutcookies.org. You can delete all cookies stored on your computer and set most browsers to prevent the storage of cookies. However, you may then have to make some settings manually each time you visit a page and accept the impairment of some functions.
