The Bundeskartellamt has imposed on Facebook far-reaching restrictions in the processing of user data.
According to Facebook's terms and conditions users have so far only been able to use the social network under the precondition that Facebook can collect user data also outside of the Facebook website in the internet or on smartphone apps and assign these data to the user’s Facebook account. All data collected on the Facebook website, by Facebook-owned services such as e.g. WhatsApp and Instagram and on third party websites can be combined and assigned to the Facebook user account.
The authority’s decision covers different data sources:
(i)     Facebook-owned services like WhatsApp and Instagram can continue to collect data. However, assigning the data to Facebook user accounts will only be possible subject to the users’ voluntary consent. Where consent is not given, the data must remain with the respective service and cannot be processed in combination with Facebook data.
(ii)    Collecting data from third party websites and assigning them to a Facebook user account will also only be possible if users give their voluntary consent.
