However, for the end user this just seems like a major privacy violation and if you agree this is an issue, I’m going to explain below how you can stop WhatsApp from sharing your phone number with Facebook.
How to stop WhatsApp from sharing your phone number with Facebook
There are two ways you can stop WhatsApp from sharing your phone number with Facebook:
Method 1 – Directly from the T&Cs
If you haven’t been greeted by the new terms and conditions yet, you will when you open WhatsApp the next time. So go ahead and launch the app, and you will be prompted to accept the company’s new terms and conditions.
Don’t tap on ‘Agree’, but choose ‘Read’ instead.
Scroll down to the bottom of the screen and you will see an option that lets WhatsApp share your account details with Facebook. Simply uncheck this option before tapping “Agree” and you’re done.
Method 2 – From WhatsApp’s settings
In WhatsApp, head over to Settings -> Account and deselect the ‘Share my account info’ option.
Also, be aware that opting out of the new terms and conditions only means your WhatsApp account details will not be shared with Facebook – the social network. Facebook – the company and other companies under it will still be able to use this data for various other reasons (typically to improve their algorithms and metrics).
