I read this Article: https://www.theguardian.com/technolo...bers-user-data
The German data protection agency has ordered Facebook to stop collecting user data from its WhatsApp messenger app and delete any data it has already received.
A Facebook spokesperson said: “Facebook complies with EU data protection law. We will work with the Hamburg DPA in an effort to address their questions and resolve any concerns.”
I'm wondering which article(s) of the EU protection law is enforced? Or where is a good place that kind of case law?
