We use the "visitor action pixels" from Facebook Inc (1 Hacker Way, Menlo Park, CA 94025, USA, or, if you are based in the EU, Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland ("Facebook")) on our website.
This allows user behavior to be tracked after they have been redirected to the provider's website by clicking on a Facebook ad. This enables us to measure the effectiveness of Facebook ads for statistical and market research purposes. The data collected in this way is anonymous to us, i.e. we do not see the personal data of individual users. However, this data is stored and processed by Facebook, which is why we are informing you, based on our knowledge of the situation. Facebook may link this information to your Facebook account and also use it for its own promotional purposes, in accordance with Facebook's Data Usage Policy
https://www.facebook.com/about/privacy/. You can allow Facebook and its partners to place ads on and off Facebook. A cookie may also be stored on your computer for these purposes.
The legal basis for the use of this service is Art. 6 paragraph 1 sentence 1 letter f GDPR. You can object to the collection of your data by Facebook pixel, or to the use of your data for the purpose of displaying Facebook ads by contacting the following address: https://www.facebook.com/settings?tab=ads.
Facebook is certified under the Privacy Shield Agreement and thus guarantees compliance with European data protection legislation (https://www.privacyshield.gov/participant? id=a2zt0000000GnywAAC&status=Active).
