These websites use the "+1" button of the social network Google Plus of Google Inc., 1600 Amphitheatre Parkway, Mountain View, California, 94043 USA, (hereinafter: "Google").
If you call a page of our website that has the "+1" button, a connection to the Google servers in the USA is made and the button is displayed on the website by communication to your browser. Here, both your IP address and the information of which of our websites you visited are transmitted to the Google server. This applies no matter if you are registered or logged in at Google Plus. Transmission takes place for users who are not registered or not logged in as well.
The "+1" button is not used in order to record your visitors in the internet. When displaying a "+1" button, Google does not permanently log your browser history and does not otherwise evaluate your visit to a page with the "+1" button. Google will save data about your visit for about two weeks for system maintenance and troubleshooting purposes. These data are, however, not structured by individual profiles, user names or URLs and also will not be forwarded to us.
If you are also a member of Google Plus and logged in at Google Plus while you use the plug-in, the collected information about your website visit will be linked to your Google Plus account as well and disclosed to other users. In case of interactions as they are possible with the different Google plugins, the corresponding information concerning you will be collected, transmitted to Google and stored there as well. For an overview of the different types of Google plugins, see here: https://developers.google.com/+/plugins
If you have made your profile publicly accessible in the settings of Google Plus, your "+1" may be displayed in Google services, such as search results or your Google profile, or in other locations on the websites and advertisements online, as notes by Google together with your profile name and your photograph.
If you do not want Google to directly assign the collected information to your Google Plus profile, you must log out of Google Plus before visiting our website.
