Persistent cookies remain in your browser even when you have closed your web browser, so that the next time you visit the platform works as set up previously.

This cookie is used by the Vimeo player. This is a session cookie.



We embed videos from our official YouTube channel using YouTube’s privacy-enhanced mode. This mode may set cookies on your computer once you click on the YouTube video player. YouTube will not store personally-identifiable cookie information for playbacks of embedded videos using the privacy-enhanced mode.


Please note that third parties (including for example advertising networks and providers of external services like web traffic analysis services) may also use cookies, over which we have no control. These cookies are likely to be analytical cookies (which count visitors to our website and monitor their web browsing) or targeting cookies (which log users’ browsing histories to display relevant adverts when a particular user next visits the website).

Facebook Pixel

We use the “visitor action pixels” from Facebook Inc (Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland (“Facebook”)) on our website. This allows user behavior to be tracked after they have been redirected to the provider’s website by clicking on a Facebook ad. This enables us to measure the effectiveness of Facebook ads for statistical and market research purposes. The data collected in this way is anonymous to us, i.e. we do not see the personal data of individual users. However, this data is stored and processed by Facebook, which is why we are informing you, based on our knowledge of the situation. Facebook may link this information to your Facebook account and also use it for its own promotional purposes, in accordance with Facebook’s Data Usage Policy https://www.facebook.com/about/privacy/. You can allow Facebook and its partners to place ads on and off Facebook. A cookie may also be stored on your computer for these purposes. The legal basis for the use of this service is Art. 6 paragraph 1 sentence 1 letter f GDPR. You can object to the collection of your data by Facebook pixel, or to the use of your data for the purpose of displaying Facebook ads by contacting the following address: https://www.facebook.com/settings?tab=ads.

Twitter Conversion Tracking

On our website, we use the Conversion Tracking Service of Twitter Inc. (1355 Market Street #900, San Francisco, California 94103, “Twitter”). Twitter stores a cookie on the user’s computer to enable an analysis of the use of our online products and services. Twitter Conversion Tracking tracks the actions of users after they have viewed ads or interacted with ads on Twitter. Twitter’s Conversion Tracking allows us to assign conversions such as link clicks, retweets or “like” data. The legal basis for the use of this service is Art. 6 paragraph 1 sentence 1 letter f GDPR. If you wish to object to tracking, you can do so using the Digital Advertising Alliance tool at optout.aboutads.info.

If you would like to disable cookies from your web browser then you need to activate the setting on your browser which allows you to refuse the setting of some or all cookies. However, blocking all cookies is likely to have a negative impact on the usability of many websites.
