Piwik
This service uses Piwik, open-source software for the statistical evaluation of user access. Piwik uses 'cookies', which are text files placed on your computer, to help the website analyse how users use the site. The information generated by the cookie about the use of the website is transmitted to and stored on the provider's server in Germany. The IP address will be anonymised immediately after processing and before its storage. Users may prevent the installation of cookies by selecting the appropriate settings on your browser; however, the provider advises the users that they may not be able to use the full functionality of this website.
Use of facebook social plugins
This site uses social plugins ("plugins") on the social network facebook.com, which is operated by Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland ("Facebook"). The plugins are indicated by one of the Facebook logos (white "f" on a blue tile, the word "Like" or a "thumbs up" icon) or with the extension "Facebook Social Plugin". The list and appearance of Facebook social plugins are available to view here: developers.facebook.com/docs/plugins/.
If a user calls up a website from here containing any such plugin, its browser will connect directly to the servers at Facebook. The content of the plugin is transmitted directly to your browser from Facebook and will be integrated into the website by the browser. Therefore, the provider does not have any control over the scope of data which Facebook collects using this plugin and, therefore, advises users accordingly on the basis of what it knows:
The integration of the plugin enables Facebook to obtain information that the user has retrieved a particular page on the website. If the user is logged into Facebook, Facebook can find details of the visit to his or her Facebook account. If users interact with the plugins, for instance click the Like button or leave a comment, the corresponding information is transmitted directly to Facebook from their browser and it is stored there. If a user is not registered on Facebook, Facebook can still learn and save his or her IP address. According to Facebook, only an anonymised IP address is saved in Germany.
Details of the purpose and scope of data collection and of the processing and use of data by Facebook, as well as of the associated rights and possible settings to protect the privacy of users can be found in the data protection notes in Facebook: www.facebook.com/about/privacy/.
If a user is registered on Facebook and does not want Facebook to collect data about him or her through this website and does not want the visit to be linked to any of his or her member data saved on Facebook, he or she must log out of Facebook before visiting the website. Further settings and objections to the use of data for publicity purposes are possible within the Facebook profile settings: www.facebook.com/settings.
+1 Button in Google+
This site uses the "+1" button for the Google Plus social network, which is operated by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States ("Google"). The button is indicated by the characters "+1" against a white or coloured background.
If a user calls up a website from here containing any such plugin, its browser will connect directly to the servers at Google. The content of the "+1" button plugin is transmitted directly to his or her browser from Google and will be integrated into the website by the browser. Therefore, the provider does not have any control over the scope of data which Google collects using this button. According to Google, no personal data is collected unless the button is clicked. This data, among other things the IP address, is only collected from members who are logged in and processed.
Details of the purpose and scope of data collection and of the processing and use of data by Google, as well as of the associated rights and possible settings to protect privacy can be found by Google users in the data protection notes about the "+1" button: www.google.com/intl/de/+/policy/+1button.html and the FAQ: www.google.com/intl/de/+1/button/.
Twitter
This site uses Twitter buttons. These buttons are provided by Twitter Inc., 795 Folsom St., Suite 600, San Francisco, CA 94107, USA. They are indicated by words like "Twitter" or "Follow", associated with a stylised blue bird. These buttons allow you to share a contribution or page from this website on Twitter or to follow the provider on Twitter.
If a user calls up a website from here containing any such plugin, its browser will connect directly to the servers at Twitter. The content of the Twitter button is transmitted directly to the user's browser from Twitter. Therefore, the provider does not have any control over the scope of data which Twitter collects using this plugin and, therefore, advises users accordingly on the basis of what it knows. According to it, only the user's IP address is transmitted to the website URL when the button is actioned; it is not used for any purpose other than for the display of the button.
