WhatsApp says the change is necessary to help it integrate better with other Facebook products.
1. What does the policy say?
WhatsApp is now reserving the right to share data it collects about you with the broader Facebook network, which includes Instagram, regardless of whether you have accounts or profiles there.
Much of the policy, which is about monetizing WhatsApp, is broadly in line with what came before, but it now states clearly that “WhatsApp receives information from, and shares information with, the other Facebook Companies. We may use the information we receive from them, and they may use the information we share with them, to help operate” and market services. The option to share data with Facebook has existed for years, but it was just that: optional. From Feb. 8 it becomes mandatory.
