These services are offered by the companies Facebook Inc., Google Inc. and Twitter Inc. Facebook is operated by Facebook Inc.1601 S. California Ave, Palo Alto, CA 94304, USA ("Facebook").

An overview of the plugins and their appearance can be found here: https://developers.facebook.com/plugins or https://twitter.com/about/resources/buttons or https://www.addthis.com/get/sharing When you call up a page of our website that contains such a plugin, your browser establishes a direct connection to the servers of Facebook, Google,Twitter and AddThis. The content of the plugin is transmitted directly to your browser by the respective provider and integrated into the page. Through the integration of the plugin, the providers receive the information that your browser has called up the corresponding page of our website, even if you do not have a profile with the corresponding social network or are not logged in. Through the integration, AddThis receives the information that your browser has called up the corresponding page of our website and stores a cookie on your end device to identify your browser. This information (including your IP address) is transmitted by your browser directly to a server of the respective provider in the USA and stored there. If you are logged in to one of the social networks, the providers can directly assign the visit to our website to your profile on Facebook If you interact with the plugins, for example by clicking the "Like" or "Tweet" button, the corresponding information is also transmitted directly to a server of the provider and stored there. The information is also published on the social network or on your Twitter account and displayed to your contacts. AddThis uses the data to create anonymous user profiles, which serve as a basis for personalized and interest-related advertising to visitors of websites with AddThis plug-ins. The purpose and scope of data collection and the further processing and use of the data by the providers as well as your rights and settings options for the protection of your privacy can be found in the providers' data protection information.
