§ 11 Web analysis and other third-party services

(1) The Service uses Google Analytics on its website. Google Analytics makes it possible for website owners to obtain information on the number of visitors to their website, where they come from and their surfing habits while on the site, which can then be used to improve the website concerned. To this end, certain data is transmitted in anonymized form to Google servers in the USA where it is automatically analyzed. The version of Google Analytics used by the Service is programmed in such a way that the last 8 digits of the user’s IP address are deleted even before the data is transmitted to the USA. This makes it impossible for the transmitted data sets to be assigned to a specific User. If the User nevertheless does not want User data to be compiled and analyzed by Google Analytics, he can follow this link and install the deactivation add-on developed by Google.

(2) The Service uses Google+, which is provided by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States (“Google”). Visiting our website involves a link to the Google server, which creates and integrates a connection to the browser of the website visitor and the website displayed. The plugin transmits the visit of our website to Google. We have no influence on the scope, content or transmission of the data and IP address of the User which Google obtains through the connection. In respect of the use of data which is transmitted to Google, the User can view the guidelines set down by Google on the following website: The Service uses so-called social plug-ins of the social network (“Facebook”). Facebook is operated by Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA. For detailed information on the functions of the various plug-ins and their appearance, please go to the following website:

(3) The service uses plugins of the social network LinkedIn from the LinkedIn Corporation, 2029 Stierlin Court, Mountain View, CA 94043, USA (hereinafter “LinkedIn”). The LinkedIn plugins are indicated by the LinkedIn logo or the “Recommend button” on the Service. When the User uses the Service, the plugin creates a direct connection between the User’s browser and the LinkedIn server. This informs LinkedIn that the User has visited the Service using a certain IP address. When the User clicks on the LinkedIn “Recommend button” while logged in to a LinkedIn account, the User can link content from the Service to the LinkedIn profile. In this way, LinkedIn allocates the User’s visit to the Service to a user account. As the owner of the Service candena is not informed about the content of the data transferred or its use by LinkedIn. See the LinkedIn Privacy Policy for details of data collection (purpose, extent, further processing, use) as well as the User’s rights and setting options. The User can find these details under:

(4) The web pages of our internet presence which contain Facebook social plug-ins establish a direct connection with the Facebook servers via the User’s browser. Facebook will then be provided with the information that the User has accessed the page of the Service which contains the social plug-in. If the User is logged into Facebook at that time, the visit to our pages as well as all of the User’s internet activities in connection with the social plug-ins (e.g. clicking the “Like” button, creating a comment etc.) can be attributed to the User’s Facebook profile and be stored on Facebook. Even if the User does not have a Facebook profile, it cannot be excluded that Facebook may store the User’s IP address. With regard to the purpose and extent of the data collection and the processing and use of such data by Facebook, we hereby make reference to the Facebook Privacy Policy: There, you will also find an overview of the setting options in the personal Facebook profile in order to protect privacy, as well as the rights associated with this. In order to prevent Facebook from collecting the above data, the User can log out of Facebook prior to visiting the Service. In order to prevent the general access by Facebook to User data on the Service, the User can exclude Facebook social plug-ins by an add-on for the browser (e.g. “Facebook-Blocker”,
