WhatsApp will now share its user data with Facebook. According to the messaging company, sharing information will help Facebook to offer better friend suggestions by mapping users’ social connections. This will also help Facebook to deliver more relevant ads on the social network. Analytics data from WhatsApp will also be shared with Facebook to track spammers.
Official blog post says,
“Even as we coordinate more with Facebook in the months ahead, your encrypted messages stay private and no one else can read them. Not WhatsApp, not Facebook, nor anyone else. We won’t post or share your WhatsApp number with others, including on Facebook, and we still won’t sell, share, or give your phone number to advertisers.”
