Data processing through social networks

Social networks such as Xing, Youtube, Facebook, Twitter, etc. can generally analyze your user behavior 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 processing operations relevant to data protection. In detail:

If 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.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, this data collection takes place, 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, you can be shown interest-based advertising 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 cannot track all processing operations on the 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 data protection provisions of the respective social media portals.

Legal basis

Our social media presences are intended to ensure the most comprehensive presence possible on the Internet. This is a legitimate interest within the meaning of Art. 6 (1) lit. f DSGVO. The analysis processes initiated by the social networks may be based on different legal bases, which are to be specified by the operators of the social networks (e.g. consent within the meaning of Art. 6 para. 1 lit. a DSGVO).

Responsible person and assertion of rights

If you visit one of our social media sites (e.g. Xing), 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 (information, correction, deletion, restriction of processing, data portability and complaint, for more details see separate entry) both vis-à-vis us and vis-à-vis the operator of the respective social media portal (e.g. vis-à-vis Xing).

Please note that despite the joint 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 largely determined by the corporate policy of the respective provider.

Storage duration

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

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 privacy policy, see below).
