Data Sharing is the Issue
Germany's largest confederation of consumer groups, known as VZBV, claims that Facebook's new "app center" violates German law by not providing notice to users or obtaining their consent to share their data, according to ars technica.
The group is apparently considering legal action if Facebook does not change its software as requested.
Data Retention May Also Bring Legal Action
Meanwhile, the Hamburg Commissioner for Data Protection and Freedom of Information has stated that he plans to reopen an investigation into how Facebook tags photos, stores and deletes data, and how much control users have regarding their information, according to Reuters.
Whether or not Facebook will face legal action in the EU will be determined by an Irish watchdog, because Facebook's non-U.S. headquarters is located in Ireland.
