What are cookies?
A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, component settings) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another. Cookies can also be used to analyse traffic and for advertising and marketing purposes. Cookies are used by nearly all websites and do not harm your system. If you want to check or change what types of cookies you accept, this can usually be altered within your browser settings.

Google may transmit the thereby collected data to a server in the US where it will be assessed and saved. For transmissions of personal data to the US, Google subjected itself to the EU-US Privacy Shield. As described above, you may also configure your browser to reject cookies. In addition to this, you may also turn off “Ads Personalization” in Ads Settings. Google will then only display general advertisements not selected on the basis of the data collected on you. For more information, please see Google’s Privacy Policy:

YouTube: We embed videos saved on YouTube that can be played directly from our website. YouTube is a multimedia service of YouTube LLC, 901 Cherry Ave., San Bruno, CA 94066, USA (“YouTube”), an affiliate of Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google”).
