Google Analytics

Google Analytics is a web analytics service offered by Google to track and report on website traffic. Google uses the data collected to track and monitor the use of our service. This data is shared with other Google services. Google may use the data collected to contextualize and customize ads from its own advertising network.

You may opt out of making your activity on the service accessible to Google Analytics by installing the Google Analytics Opt-out Browser Add-on. The add-on prevents Google Analytics JavaScript (ga.js, analytics.js, and dc.js) from sharing information with Google Analytics about visit activity.

Facebook Custom Audience and Facebook Pixel

We use the Facebook pixel, a service of Facebook Ireland Limited, on our website: hereinafter referred to as “Facebook”). Using the Facebook pixel, Facebook is able to identify visitors to our website as a target group for the placement of ads (referred to as “Facebook Ads”). Therefore, we use the Facebook pixel so that the Facebook Ads we publish are only visible to Facebook users who have also expressed an interest in our online offering or who have certain characteristics (e.g., interests in certain topics or products determined by the websites visited) that we pass on to Facebook (so-called “personalized audiences”). With the Facebook pixel, we want to ensure that our Facebook Ads meet the potential interest of users in our products and do not represent a source of nuisance. The Facebook pixel also helps us to discern the effectiveness of Facebook Ads for statistical and market research purposes by telling us whether users have been redirected to our website after clicking on a Facebook Ad (this is called “conversion”).

Facebook processes the data in accordance with Facebook’s data use policy, which can be found here: Specific information and details about the Facebook pixel and how it works can be found in the Facebook Help section:

We use the Facebook pixel and Facebook’s Custom Audience feature for marketing analysis and optimization purposes, including delivering relevant and interesting ads, improving campaign performance reporting and balancing our advertising budget. We also have a legitimate interest in the processing of the above data by the third party provider. The legal basis is art. 6 par. 1 point f) GDPR.

As a Facebook user, you have the opportunity to object to the collection by the Facebook pixel and the use of your data to display Facebook ads. Here you can change the settings for the types of ads (usage-based ads) displayed to you on Facebook: The settings are platform-independent, i.e. they apply to all devices, such as desktops or mobile devices.

Facebook complies with the data protection provisions of the US Privacy Shield Agreement and is a participant in the US Department of Commerce’s US Privacy Shield program.

This site is not part of the Facebook or Facebook Inc. website and is in no way endorsed by Facebook. FACEBOOK is a trademark of FACEBOOK, Inc.
