With the recent upgrade of Whatsapp, many people might not have taken notice about the Sharing of Your Information with Facebook.
If you are not happy or comfortable with sharing your information with Facebook, there is a way to opt out of it.
Open WhatsApp on your phone.
On Android, tap the action overflow button in the upper right corner and select Settings.
On iOS, tap the Settings tab in the lower right corner.
Tap the check mark to the right of Share my account info.
To disable the feature, tap Don’t Share.
The pop-up that appears reads, “If you tap ‘Don’t Share’, you won’t be able to change this in the future.” And they mean it.
After you follow through with this action, the option will no longer be visible from the Account section of Settings and there is no turning back.
So be sure on whether you’d like your privacy or whether you’d like Facebook to ‘Share’ your information with a view to improving “targeted ads’… although… how your phone number helps this, I have no idea.
