Use of Facebook social plugins
Our Internet pages utilise social plugins ('plugins') from the social network, which is operated by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA ('Facebook'). These plugins are identified by one of the Facebook logos or bear the suffix 'Facebook social plugin'. A list of Facebook Social Plugins showing their appearance may be viewed here: When you access one of our Internet pages containing a plugin of this kind, your browser establishes a direct link with the Facebook servers. The content of the plugin is transferred directly to your browser by Facebook and thereby incorporated into the web site; for this reason, we have no control over the volume of data collected by Facebook via the plugin. We therefore draw attention to our level of knowledge: where plugins are incorporated, Facebook obtains the information you call up on one of our Internet pages. If you are logged in to Facebook at the time, Facebook can assign your visit to your Facebook account. When you interact with a plugin (for example, by pressing the Like button or posting a comment), the relevant data is sent straight from your browser to Facebook, where it is stored. If you are not a member of Facebook, Facebook may still ascertain and store your IP address. For more information on the purpose and extent of data collection and the subsequent processing and usage thereof by Facebook as well as your rights in this regard and settings to protect your privacy, please refer to Facebook's data use policy: If you have a Facebook account and do not wish Facebook to collect your data via our Internet pages and link this to your account data already stored with Facebook, you must log out of Facebook before visiting our Internet pages. It is also possible to block Facebook social plugins by means of add-ons for your browser such as 'Facebook Blocker'.
