Our social media presence

Data processing through social networks

We have publicly accessible profiles on social networks. The individual social networks used by us are listed individually below.

Social networks like Facebook, Twitter, etc. can generally analyze your user behavior extensively when you visit their website or a website with integrated social media content (e.g. like buttons or advertising banners). Numerous processing procedures relevant to our social media presences are initiated by a visit to our social media presences. In detail:

When you are logged into 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. In certain circumstances, your personal data can also be collected if you are not logged in or do not have an account in the respective Social Media Portal. This data collection is done for instance via a Cookie in this case that is saved on your terminal device or by acquiring your IP-address.

With the help of the data collected in this way, the operator of the social media can create user profiles that file your preferences and interests. In this way, interest-related advertising can be displayed inside and outside of the respective social media presence. Insofar as you have an account in the respective social network, interest-related advertising can be displayed on all devices that you are logged into or were logged into.

Please also note that we cannot track all processing steps on social media portals. Depending on the provider, it is possible that further processing procedures are performed by the operator of the social media portals. For details please see the usage conditions and data protection regulations of the respective social media portals.

Legal basis

Our social media presences should guarantee an online presence that is as extensive as possible. This is a legitimate interest as per Art. 6 Para. 1 lit. f DSGVO. The analysis processes initiated by the social networks may be based on a deviating legal basis that must be provided by the operators of social networks (e.g. consent as part Art. 6 Para. 1 lit. a DSGVO).

Person in charge and enforcement of rights

When you visit our social media presences (e.g. Facebook), we are responsible together with the operator of the social media platform for the data processing procedures initiated by this visit. You can generally enforce your rights (disclosure, correction, deletion, limitation of processing, data transfer and complaints) against us as well as against the operator of the respective social media portal (e.g. against Facebook).

Please note that despite mutual responsibility with the social media portal operators we do not have influence over the data processing procedures of the social media portals. Our options conform significantly to the company politics of the respective provider.

Duration of storage

The data collected by us directly through social media presence is deleted as soon as the purpose for its saving has lapsed, you have requested it be deleted, withdrawal of your consent to it being saved or the purpose for data processing has lapsed. The saved Cookies remain on your terminal device until you delete them. Mandatory legal provisions – esp. retention periods – remain unaffected.

We have no influence on the duration that your data is stored by the operator's of social networks for their own purposes. For details please inform yourself directly from the social media operators (e.g. from their data protection declarations, see below).
