Social media data protection

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, Twit­ter etc. can gen­er­al­ly ana­lyze your user behav­ior 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 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).
