Facebook is updating its terms of service and data policy to clarify what user information it collects and shares across its family of products including Instagram, WhatsApp, Oculus and Messenger.
The revised policies come at a time when the company is being scrutinized over how it shares personal information with third parties, especially in light of the Cambridge Analytica data leak. The new terms of service and data policy doesn't ask for more user data rights or change privacy controls.
