Privacy policy for social networks

Our presence on social media

Data processing through social networks
We maintain publicly accessible profiles on social networks. The social networks we use in detail can be found below.

Social networks such as Facebook, Google+, etc., can usually comprehensively analyse your user behaviour if you visit their website or a website with integrated social media content (e.g. Like buttons or advertising banners). Visiting our social media pages triggers numerous processing operations that are relevant under data protection legislation. In detail:

If you are logged in to your social media account and visit our social media page, the operator of the social media portal can assign this visit to your user account. Your personal data may also be collected under certain circumstances, even if you are not logged in or do not have an account with the social media portal in question. In this case, this data is collected using cookies stored on your terminal device or by collecting your IP address, for example.

The data collected in this way allows the operators of social media portals to create user profiles that your preferences and interests are stored in. In this way, interest-based advertising can be displayed both within and outside of the social media page in question. If you have an account with the relevant social network, interest-based advertising can be displayed on all devices that you are or were logged in on.

Please also note that we are cannot track all processing activities on the social media portals. Depending on the provider, the operators of the social media portals may therefore carry out further processing operations. For details, please refer to the terms of use and privacy policies of the relevant social media portals.

Legal basis
Our social media pages are designed to ensure the most comprehensive online presence possible. This is a legitimate interest under Art. (6) (1) (f) of the GDPR. The analytics 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 under Art. 6 (1) (a) of the GDPR).

Controller and assertion of rights
When you visit one of our social media pages (e.g. Facebook), we are jointly responsible with the operator of the social media platform for the data processing operations triggered during this visit. You may assert your rights (right of access, right to rectification, right to erasure, right to restriction of processing, right to data portability and right to lodge a complaint) in principle both against ourselves and the operator of the relevant social media portal (e.g. against Facebook).

Please note that, despite our joint responsibility with the operators of the social media portal, we do not have full influence over the social media portals’ data processing operations. Our options depend largely on the relevant provider’s corporate policy.

Duration of storage
The data that we collect directly using the social media page shall be erased from our systems as soon as the purpose for storing the same ceases to apply, you request that we erase the same, you revoke your consent to storage or the purpose for data storage ceases to apply. Stored cookies remain on your terminal device until you delete them. Mandatory statutory provisions – particularly retention periods – remain unaffected.

We have no influence over how long your data stored by the operators of the social networks for their own purposes is stored for. For details, please contact the operators of the social networks directly (e.g. in their privacy policy; see below).
