This data exchange will allow Facebook to improve its ad targeting and ‘product experiences’ predominantly by accessing your friend list and your content browsing history. However, the policy says, “Nothing you share on WhatsApp, including your messages, photos, and account information, will be shared onto Facebook…”
This has left the facebook users in anguish as The Guardian reports, “Facebook is being accused of backtracking on its pledge not to use the data of the 1 billion users of the WhatsApp messaging app it acquired two years ago”. We didn’t expect any less, did we?
Right, so if you don’t like your number being shared with Facebook, you can turn off the data sharing in Whatsapp. Simply go to Settings > Account > Turn OFF Sharing
and Voila!!! Freedom!
