How do I stop WhatsApp from sharing my phone number with Facebook? WhatsApp has an in-app opt out option. Here’s how you tell WhatsApp, “no way”!
Facebook and the other companies in the Facebook family also may use information from us to improve your experiences within their services such as making product suggestions (for example, of friends or connections, or of interesting content) and showing relevant offers and ads.
How do I opt out?
Launch WhatsApp.Tap Settings.Tap Account.
Tap the switch to disable Share My Account Info.
Tap Don’t Share.To confirm you’ve opted out, check to see that Share My Account Info is grayed out.
That’s it! You’ve successfully opted out of WhatsApp sharing your account information for advertisement and product purposes. Of note, WhatsApp says Facebook will still have access to your information for “other purposes,” including fighting spam and improving security.
