User details including phone numbers will now be given to Facebook once you sign up for the new terms and conditions and WhatsApp has given a deadline to opt out of the gross violation of privacy, which the company with a 1 billion strong user base had promised to protect.
Here’s how you can opt out of the service:
1. When you launch WhatsApp, you will see the updated Terms of Service asking you to authorize WhatsApp to share you personal details with Facebook. Scroll down and you will find a checkbox. Uncheck it and tap on Agree and you are set.
2. Already accepted the new Terms of Service? There’s still a way. Go to Setting and select account. Once in there, uncheck the box where it asks ‘Share my account info’ and your details remain protected.
3. WhatsApp uses phone numbers to verify unique users. If the user also happen to have the Facebook app installed (which is the most likeliest case), then Facebook will have full access to all the device information through WhatsApp.
While Facebook won’t go out and give away your phone number to the public, it will provide friend suggestion based on phone contacts. Users who have your phone number saved in their contact lists but haven’t added you on Facebook yet, will start seeing your profile under’Friends Suggestions’.
The move will provide ad-targeting for businesses in more invasive ways. Say your favorite pub in town has your number in their mailing list, the same number which WhatsApp has used to verify you. Whenever the pub will post an advertisement on Facebook, you will be seeing them on your news feed, even though you didn’t like the Facebook page of the pub.
The data sharing will also help Facebook track usage metrics and strengthen its spam filters.
