In order for this website to function properly, we sometimes place small files – so-called cookies – on your device. This is common practice for most large 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. This allows the portal to “remember” certain entries and settings (e.g. login, language, font size and other display preferences) over a certain period of time so that you do not have to enter them again each time you visit and navigate the portal.

How do we use cookies?

We use cookies on our pages to store

• your preferences for the screen display, e.g. contrast and font size
• Your possible participation in a survey on the usefulness of the content (so that you are not prompted 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 pages also use cookies to generate anonymous statistics about the previously visited pages and the selected videos.

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

The information collected using cookies is not used to identify you and the data is entirely under our control. The cookies do not serve any purposes other than those mentioned here.

Control over cookies

You can control and/or delete cookies as you wish. 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.
