We use our own cookies, third-party cookies and similar technologies on our website. Some of these are necessary to ensure that you can use our platform securely. Others are not absolutely necessary, but help us, for example, to evaluate and improve the use of our website. A distinction is made between „Necessary cookies“, „Functionality & Comfort“, „Statistics & Analysis“ and „Marketing“. Marketing cookies are also used for ads personalisation. This also involves setting cookies from Google (Google's privacy policy). Further information can be found in our Privacy Policy and Cookie Details.

There you will also find further information on the purposes and third-party providers used. If you allow these, your consent also includes the transfer of data to third countries that do not have a level of data protection comparable to that in the EU and/or the UK.
