WhatsApp announced that it would begin sharing user data with its parent company, Facebook, to "improve user ads and products experiences." This understandably caused a bit of a stir among fans of the mobile messaging app, which consistently promises to protect user data from advertisers. If you're among the group of people who are against sharing your WhatsApp information with Facebook, you'll be glad to know that you can opt out of doing so.
This tutorial will show you how to change your WhatsApp settings so that it won't share your data with Facebook for ads.

N.B. These steps only forbid Facebook from using your data for advertising purposes. According to WhatsApp, Facebook will still "receive and use this information for other purposes, such as improving infrastructure and delivery systems, understanding how our services or theirs are used, securing systems, and fighting spam, abuse, or infringement activities."
