This Cookie Policy explains what cookies are, how we use them, and which choices you have with regard to cookies.
Cookies are small text files that are stored on your device (computer, tablet or mobile phone) when you visit a website. They are widely used to make websites work more efficiently and to provide information to the website operators.

The same rules apply (Section 25 TDDDG): strictly necessary storage or storage explicitly requested by you takes place without consent (Section 25(2) no. 2 TDDDG); everything else only with your consent.
