Our Internet presence uses social plug-ins ("plug-ins") of the social network facebook.com that is operated by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA ("Facebook"). The plug-ins are designated through the Facebook logo or use of the phrase “Facebook social plug-in.” When you call up a Web site that is part of our Internet presence and that contains such a plug-in, then your browser connects directly with the servers of Facebook. The content of the plug-ins are transmitted directly to your browser from Facebook and then used to incorporate them into the Web site. By incorporating the plug-ins Facebook receives information that you have called up the corresponding page of our Internet presence. If you are logged in to Facebook, then Facebook can assign the visit to your Facebook account. If you interact with the plug-ins, e.g. if you use the "like" feature or provide commentary, then the corresponding information will be transferred from your browser directly to Facebook and stored there. The purpose and extent of data collection, the further processing and use of data by Facebook, as well as your rights in this regard and the various possible settings to protect your privacy are to be found in Facebook's data protection guidelines. If you do not wish for Facebook to use our Internet presence as a way to collect information about you, then you must log out of Facebook before visiting us on the Internet.
