On our pages, plugins are integrated into the social network Facebook, 1601 South California Avenue, Palo Alto, CA 94304, USA. You can recognize the Facebook plugin by the Facebook logo or the "Like Button" ("Like") on our website. An overview of Facebook plugins can be found here: developers.facebook.com/docs/plugins/. When you visit our webpages, a direct connection between your browser and the Facebook server is made via the plugin. Facebook thereby receives the information that you have visited our site using your IP address. If you click on the Facebook "Like" button while you are logged into your Facebook account, you can link the contents of our webpages to your Facebook profile. This allows Facebook to assign your visit to our website to your user account.
