Our website also contains programmes (plug-ins) of the social network Facebook. They are used solely by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA (Facebook). On our website the plug-ins are marked by the Facebook logo. An overview of the Facebook plug-ins is available here: http://developers.facebook.com/docs/plugins/
Our plug-ins require two clicks to activate, to protect users from unwanted data transfer. Only when you deliberately activate the plug-in by clicking on the marked button will your browser create a direct connection to Facebook’s servers. This in turn will transfer the information contained in the plug-in to your browser, which will integrate it into the website shown. This shall involve the transfer to Facebook of the information that you have visited our website and your IP address. The activation of the plug-in will be saved in your browser via a cookie. Should you delete cookies in your browser, you will also deactivate communication with the Facebook server and will have the opportunity to reactivate the plug-in the next time you visit our website. If you are logged into your personal user account at Facebook while using our website, you can link the information on our pages to your Facebook profile. Moreover, Facebook can then assign the website visit to this account. By interacting with plug-ins, e.g., clicking the “Like” button or leaving a comment, the corresponding information will be sent directly to Facebook and saved there.
We wish to point out that we as site provider receive no information on the content of the data transferred or regarding their use by Facebook. Should you wish to prevent such a data transfer, you must log out of your Facebook account or deactivate cookies before visiting our website.
