§ 9 Incorporation of YouTube videos

(1) We have integrated YouTube videos into our online product, which are stored at and can be viewed directly from our website.

(2) When you visit the website, YouTube is informed that you have visited the relevant subpage of our website. In addition, the data mentioned under 3 of this Policy is communicated. This does not depend on whether or not YouTube makes a user account available, via which you are logged-in. If you are logged in at Google your data will be directly attributed to your account. If you do not want attribution to your profile by YouTube, you have to log out before activating the button. YouTube stores your data as a user profile and uses it for advertising and market research purposes and/or to design its website based on user preferences. Such an analysis is conducted especially (even for unlogged users) in order to present advertising based on user preferences and in order to inform other users of the social network about your activities on our website. You are entitled to object to the compilation of such user profiles, and to do so you have to contact YouTube.

(3) Further information on the purpose and scope of data collection and its processing by YouTube is available in the data privacy declaration.
