Our social media appearances

Data processing through social networks

We maintain publicly available profiles in social networks. The individual   social networks we use can be found below.

Social networks such as Facebook, Google+ etc. can generally analyse your user   behaviour comprehensively if you visit their website or a website with   integrated social media content (e.g. like buttons or banner ads). When you   visit our social media pages, numerous data protection-relevant processing   operations are triggered. 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. Under certain circumstances, your personal data may also be   recorded 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 stored on your device or by recording your IP address.

Using the data collected in this way, the operators of the social media   portals can create user profiles in which their preferences and interests are   stored. This way you can see interest-based advertising inside and outside of   your social media presence. If you have an account with the social network,   interest-based advertising can be displayed on any device you are logged in to   or have logged in to.

Please also note that we cannot retrace all processing operations on the   social media portals. Depending on the provider, additional processing   operations may therefore be carried out by the operators of the social media   portals. Details can be found in the terms of use and privacy policy of the   respective social media portals.

Legal basis

Our social media appearances should ensure the widest possible presence on the   Internet. This is a legitimate interest within the meaning of Art. 6 (1) lit.   f GDPR. The analysis processes initiated by the social networks may be based   on divergent legal bases to be specified by the operators of the social   networks (e.g. consent within the meaning of Art. 6 (1) (a) GDPR).

Responsibility and assertion of rights

If you visit one of our social media sites (e.g., Facebook), we, together with   the operator of the social media platform, are responsible for the data   processing operations triggered during this visit. You can in principle   protect your rights (information, correction, deletion, limitation of   processing, data portability and complaint) vis-à-vis us as well as vis-à-vis   the operator of the respective social media portal (e.g. Facebook).

Please note that despite the shared responsibility with the social media   portal operators, we do not have full influence on the data processing   operations of the social media portals. Our options are determined by the   company policy of the respective provider.

Storage time

The data collected directly from us via the social media presence will be   deleted from our systems as soon as the purpose for their storage lapses, you   ask us to delete it, you revoke your consent to the storage or the purpose for   the data storage lapses. Stored cookies remain on your device until you delete   them. Mandatory statutory provisions - in particular, retention periods -   remain unaffected.

We have no control over the storage duration of your data that are stored by   the social network operators for their own purposes. For details, please   contact the social network operators directly (e.g. in their privacy policy,   see below).
