a. Google AdWords

We employ the "AdWords" procedure of Google in order to place adverts in Google’s advertising network in such a way that they are displayed to users who are potentially interested in our adverts. In this case when they are accessed on our and other websites on which Google’s advertising network is active, a code is executed by Google and so-called marketing tags (also known as web beacons) are attached. With their help, an individual cookie is stored on your device (instead of cookies alternative technologies can also be used). This notes which websites you have visited, and which contents interested you or which pages you clicked on; furthermore, technical information and other details are stored for further use. Moreover, an individual “conversion cookie” is installed. The information obtained with the help of this is used by Google to establish conversion statistics for us. We only learn, however, the anonymous total number of users who have clicked on our advert and who have been transferred onwards to a page which has a marketing tag attached to it. The users‘ data are processed under a pseudonym within Google’s advertising network, unless they have chosen some other setting. The information collected is transmitted to Google and saved on their servers in the USA. You will find further information as to the use of the data by Google and options regarding settings and objections as well as the settings for the display of adverts under  https://policies.google.com/technologies/ads or https://adssettings.google.com/authenticated.

b. Google Retargeting  

We use Google’s retargeting technologies. This makes it possible to send to users of our website in a targeted fashion advertising linked to their interests such as they have already shown for our website and our products. The display of adverts follows on from a  cookie-based analysis of the previous behavior of the user, but no personal data is stored during this process. In the retargeting a cookie is installed on your device in order to collect anonymized data concerning your interests. This means that you are shown adverts which are most probably more related to the products which interest you. You can prevent the storing of cookies for the purpose of retargeting by installing the following plugin: https://www.google.com/settings/ads/onweb/. You can find further information about the data processing connected with retargeting by Google under http://www.google.com/policies/technologies/ads/.
