§ 5 Use of Social-Media-links

  1. We currently use the following Social-Media-Links: Facebook, Twitter, Xing, LinkedIn and Youtube. With these links, we enable you to interact and communicate with the social media and other users, so that we can improve our offer and make it more interesting for you as a user. We use the so-called two-click solution. This means that when you visit our page, personal data in principle will not be passed on to the providers of the social media provider initially. The social media provider is indicated by the mark on the box above its first letter or the logo. We enable you to communicate directly with the social media provider using the button. Only if you click the marked field and activate it this way, the social media provider will be informed that you have called the corresponding website of our online offer. The data named in § 3 of this statement will be transmitted as well. Activation of the links will therefore transmit personal data concerning you to the respective social media provider, where they will be stored (under some circumstances in the USA for US providers). Since the social media provider collects data in particular using cookies, we recommend that you delete all cookies via the safety settings of your browser.

We also have no information on deletion of the data collected by the social media provider. Contact the providers of the social media to that extent. Against this background, we recommend reading the respective current data protection notes of the social media provider named above.
  3. DData will be transmitted independently of whether you have an account with the social media provider and are logged in there. If you are logged in with the social media provider, your data collected by us may be associated directly with your account with the plug-in provider. We recommend that you regularly log out after using a social network, in particular before activating the button, since this may prevent assignment to your profile with the social media provider.
  4. We do not store the data. Information on the storage duration and further information on the purpose and scope of data collection and processing by the social media provider is available in the following data protection statements of these providers. It also contains further information on your rights to that extent and setting options for protecting your privacy.
