Use of social media plug-ins

  1. We currently use the following social media plug-ins: Facebook, Instagram. We use the so-called two-click solution. This means that when you visit our site, no personal data is initially passed on to the providers of the plug-ins. You can recognize the provider of the plug-in by the respective logo. We offer you the possibility to communicate directly with the provider of the plug-in via the button. Only if you click on the logo and thereby activate it, the plug-in provider receives the information that you have accessed the corresponding website of our online offer. In addition, the data mentioned under point 3 of this declaration will be transmitted. In the case of Facebook, according to the provider in Germany, the IP address is anonymized immediately after collection. By activating the plug-in, personal data is transferred from you to the respective plug-in provider and stored there (for US providers in the USA). Since the plug-in provider collects data via cookies in particular, we recommend that you delete all cookies before clicking through your browser’s security settings.
  2. We do not have any influence on the data collected and data processing operations, nor are we aware of the full extent of data collection, the purposes of processing, the storage periods. We also do not have any information on the deletion of the data collected by the plug-in provider.
  3. The plug-in provider stores the data collected about you as user profiles and uses these for the purposes of advertising, market research and/or demand-oriented design of its website. Such an evaluation takes place in particular (also for non-logged in users) for the representation of appropriate advertisement and in order to inform other users of the social network about your activities on our website. You have a right of objection to the creation of these user profiles, whereby you must contact the respective plug-in provider to exercise this right. Through the plug-ins we offer you the possibility to interact with social networks and other users, so that we can improve our offer and make it more interesting for you as a user. The legal basis for the use of the plug-ins is Art. 6 para. 1 s. 1 lit. f GDPR.
  4. The data is transferred regardless of whether you have an account with the plug-in provider and are logged in there. If you are logged in with the plug-in provider, your data collected with us will be directly assigned to your existing account with the plug-in provider. If you click the activated button and, for example, link the page, the plug-in provider also stores this information in your user account and shares it publicly with your contacts. We recommend that you log out regularly after using a social network, especially before activating the button, as this way you can avoid being assigned to your profile with the plug-in provider.
  5. For more information on the purpose and extent of data collection and its processing by the plug-in provider, please refer to the data protection declarations of these providers as notified below. They will also provide you with further information about your rights concerning this matter and setting options to protect your privacy.
