Social media

Data processing through social networks

Social networks such as Xing, Youtube, Facebook, Twitter etc. can usually comprehensively analyse your user behaviour when you visit their website or a website with integrated social media content (e.g. .B like buttons or advertising banners). By visiting our social media presences, numerous data protection-relevant processing processes are triggered. 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 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, which are stored on your terminal device or by collecting 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 see interest-based advertising inside and outside your social media presence. If you have an account with the respective social network, the interest-based advertisement may be displayed on all devices on which you are logged in or logged in.

Please also note that we cannot track all processing processes 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. Details of this can be found in the terms of use and data protection provisions of the respective social media portals.
