We use social plug-ins from facebook.com, operated by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA. The plug-ins can be recognized by way of the Facebook logo or the supplement "Facebook Social Plug-in". For example, if you click on the "Like" button or leave a comment, the relevant information is transmitted directly from your browser to Facebook and stored there. Furthermore, Facebook makes your likes public for your Facebook friends. If you are logged into Facebook, it can assign the invocation of our page directly to your Facebook account. Even if you are not logged in or don't have a Facebook account, your browser sends information (e.g. which web pages you have called up, your IP address) which is then stored by Facebook. For details about handling of your personal data by Facebook and your related rights, please refer to the data privacy policy of Facebook: http://www.facebook.com/policy.php. If you do not want Facebook to map data collected about you via our Web sites to your Facebook account, you must log out of Facebook before you visit our web pages.
