Our websites use so-called social plug-ins ("plug-ins") of social networks, particularly Facebook’s "Share"-button. The provider’s website, i.e. facebook.com, is operated by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA. However, Facebook Ireland Limited, Hanover Reach, 5-7 Hanover Quay, Dublin 2, Ireland, is responsible for the German website facebook.de. The plug-ins are generally marked with the Facebook logo. In addition to Facebook’s plug-ins, we also use those of "Google+" (provider: Google Inc., Amphitheatre Parkway, Mountain View, CA 94043, USA), "Twitter" (provider: Twitter, Inc., 1355 Market St, Suite 900, San Francisco, CA 94103), "Pinterest" (provider: Pinterest Inc., 808 Brannan Street San Francisco, CA 94103, USA), "XING" (provider: XING AG, Dammtorstraße 30, 20354 Hamburg, Germany), and "LinkedIn" (provider: LinkedIn Corp., 2029 Stierlin Court Mountain View, CA 94043, USA).
For data protection reasons we decided not to incorporate direct plug-ins from social networks, but to use the so called "Shariff Wrapper". Shariff Wrapper enables you to decide, whether and when to transfer data to social networks. As a consequence thereof, data will not be transferred automatically to social networks like Facebook, Google+, Twitter, Pinterest, XING or LinkedIn when visiting our websites. Your internet browser will not connect to the corresponding servers of the social network until you have not actively clicked on the respective share-button. By clicking the respective button (e.g. "Share", or "Pin it"), you give your explicit consent that your internet browser will connect to the corresponding servers of the social network and that user data will be transferred to the provider of the respective social network.
