Social media privacy policy

Our social media presence


We maintain publicly accessible profiles on social networks. The specific social networks we use can be found below.

Social networks such as Facebook, Google+, 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). Visiting our social media presence triggers numerous processing operations for which data protection is relevant. These are, specifically:

If you are logged into your social media account and visit our social media presence, the operator of the social media portal can link this visit to your user account. However, your personal data may also be collected under certain circumstances if you are not logged in or do not have an account with the respective social media portal. In this case, your data will, for instance, be collected using cookies that are stored on your device or by recording your IP address.

Data collected in this manner allows the operators of social media portals to create user profiles containing your preferences and interests. This makes it possible to display interest-based advertising to you on and outside of the respective social media presence. If you have an account with the respective social network, the interest-based advertising may be displayed on all devices on which you are or were logged in.

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

Legal basis

Our social media presences are designed to ensure the broadest possible presence on the internet. This is a legitimate interest as used by point (f) of Art. 6 (1) 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 as per point (a) Art. 6(1) 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. In principle, you can assert your rights (access, correction, erasure, restriction of processing, data portability and complaint) both against us and against the operator of the respective social media portal (e.g. against Facebook).

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

Storage duration

The data collected directly by us via our social media presence will be deleted from our systems as soon as the purpose for storing it no longer applies, you request us to delete it or revoke your consent to store it. Stored cookies remain on your device until you delete them. Mandatory legal provisions – in particular retention periods – remain unaffected by the above.

We have no influence on the storage period of data that is stored by the operators of the social networks for their own purposes. For details, please familiarize yourself with the policies of the social network operators directly (e.g. in their privacy policy, see below).
