Data processing through social networks

We maintain publicly accessible profiles in social networks. The social networks we use in detail can be found below.
Social networks such as Facebook, Google+ etc. can usually analyse your user behaviour comprehensively when you visit their website or a website with integrated social media content (e.g. Like buttons or advertising banners). Visiting our social media presences triggers numerous data protection-relevant processing operations.

In detail:
If you are logged in to your social media account and visit our social media presence, the operator of the social media portal can assign this visit to your user account. However, your personal data may also be collected if you are not logged in or do not have an account with the respective social media portal. In this case, this data is collected, for example, via cookies that are stored on your end device or by recording your IP address.

With the help of the data collected in this way, the operators of the social media portals can create user profiles in which your preferences and interests are stored. In this way, interest-based advertising can be displayed both inside and outside the respective social media presence. If you have an account with the respective social network, the interest-based advertising can be displayed on all devices on which you are or were logged in.

Please also note that we are not able to track all processing on the social media portals. Depending on the provider, the operators of the social media portals may therefore carry out further processing procedures. Details can be found in the terms of use and privacy policy of the respective social media portals.

Legal principles

Our social media appearances are designed to ensure the most comprehensive presence possible on the Internet. This is a legitimate interest within the meaning of Article 6 paragraph 1 lit. f GDPR. The analysis processes initiated by the social networks may be based on different legal bases which must be specified by the operators of the social networks (e.g. consent within the meaning of Article 6 paragraph 1 lit. a GDPR).

Controller and assertion of rights

If you visit one of our social media sites (e.g. Facebook), we are jointly responsible with the operator of the social media platform for the data processing operations triggered during this visit. As a matter of principle, you can exercise your rights (information, rectification, erasure, restriction of processing, data transferability and complaint) both against us and against the operator of the respective social media portal (e.g. against Facebook).

Please note that, despite joint responsibility with the social media portal operators, we do not have full influence on the data processing procedures of the social media portals. Our possibilities depend largely on the corporate policy of the respective provider.

Retention period

The data collected directly by us via the social media presence will be erased from our systems as soon as the purpose for storing lapses, you request us to erase them, withdraw your consent to store them or the purpose for storing the data no longer applies. Saved cookies remain on your device until you delete them. This is without prejudice to compelling legal provisions, especially retention periods.

We have no influence on the storage period of your data, which is stored by the operators of social networks for their own purposes. For details, please contact the operators of the social networks directly (e.g. in their data protection declaration, see below).
