Social plugins are integrated on certain webpages of our website, e.g. Facebook, Twitter, LinkedIn, Google+ and/or Youtube. The social plugins are identified with the companies’ logo, comment fields or what are known as a »Like« or »+1« button. When you visit a page that displays such a plugin your browser will create a direct connection to the respective social media provider server. At the same time Facebook, Twitter, LinkedIn and/or Google will know that the respective page on our website has been visited. If you are registered and have logged in with the provider concerned, your visit can also be assigned to your user account. Social media provider such as Facebook, Twitter, LinkedIn, Google+ and Youtube do not provide specific information about which data is transmitted in the use of their social plugins. We therefore have no knowledge regarding the content and scope of the transmitted data or its use by Facebook, Twitter, LinkedIn, Google+ and Youtube. Please refer to the further information about this in the data protection regulations of the social media services which are found here: Facebook, Twitter, LinkedIn, Google+ and Youtube. If you do not wish a provider to collect data on you through our website, please deactivate the plugins in your web browser. If you wish to avoid a link to any existing user account, you must log out before your visit to our website.
