On our website we promote a project by c't, called "Shariff". "Shariff" replaces the typical share-buttons of social networks and thereby protects surfing behavior
"Shariff" integrates the share buttons of social networks on our website as a graphic containing a link to the appropriate social network. By clicking on the appropriate icon you will be redirected to the services of your network. The Shariff button provides direct contact between the social network and our users only when the visitor actively clicks the 'Share' button. Only then will your data be transferred to the respective social network. If, however, the Shariff button is not clicked, no exchange will be made between you and the social network. For more information about the c't project "Shariff" visit www.heise.de/ct/artikel/Shariff-Social-Media-Buttons-mit-Datenschutz-2467514.html
The following social networks are integrated on our website with "Shariff":
Our website uses social plugins (“plugins”) provided by the social network facebook.com, operated by Facebook Inc., 1601 S. California Avenue, Palo Alto, CA 94304, USA (“Facebook”). The plugins are identifiable by a Facebook logo (white letter f on blue background or a thumb up icon) or the notice “Facebook Social Plugin”. For a full list of all social Plugins please see developers.facebook.com/plugins.
When you visit a page of our website that contains a social plugin, your browser establishes a direct connection to Facebook servers. Facebook directly transfers the plugin content to your browser which embeds the latter into the website, enabling Facebook to receive information about your having accessed the respective page of our website. Thus we have no influence on the data gathered by the plugin and inform you according to our state of knowledge:
The embedded plugins provide Facebook with the information that you have accessed the corresponding page of our website. If you are logged into Facebook, your visit can be assigned to your Facebook account. If you interact with the plugins, for example by clicking “Like”, or entering a comment, the corresponding information is transmitted from your browser directly to Facebook and stored by it. Even if you are not logged into Facebook, there is possibility that the plugins transmits your IP-address to Facebook.
If you are a Facebook member and do not want Facebook to connect the data concerning your visit to our website with your member data already stored by Facebook, please log off Facebook before entering our website. Further you can block Facebook social Plugins by using add-ons for your browser, like the “Facebook Blocker“.
Our website employs components provided by the network LinkedIn. LinkedIn is a service of LinkedIn Corporation, 2029 Stierlin Court, Mountain View, CA 94043, USA. Each time our website receives an access request equipped with a LinkedIn component, the component prompts your browser to download an image of this component from LinkedIn. Through this process, LinkedIn is informed exactly which page of our website is being accessed. By clicking the LinkedIn “recommend button“ while logged into your LinkedIn account, you can link content from our website to your LinkedIn profile. This allows LinkedIn to associate your visit to our site with your LinkedIn account.
