Germany's data protection regulator has ordered Facebook to stop collecting and storing data from WhatsApp users in the country. Facebook also must delete any data it already may have harvested from German WhatsApp users, according to Johannes Caspar, Hamburg Commissioner for Data Protection and Freedom of Information, who issued the order. Even though Facebook purchased WhatsApp two years ago, they are two independent companies, noted the commissioner, and WhatsApp can not share data with Facebook without first obtaining a user's consent.
