When Facebook acquired WhatsApp for $19 billion in 2014, WhatsApp founder Jan Koum promised that the popular app will remain autonomous and operate independently. It was certainly an incompatible marriage. Facebook is a public social platform while WhatsApp is where you share the most private of information with your friends and family. Unfortunately, things have now become ugly and WhatsApp will share your phone number with Facebook.
Finally, you must know that not everyone received the updated policy terms. If you haven’t received a notification to accept them, then your personal details are safe, for now. When you do receive a notification, remember to follow the instructions and uncheck the box that grants Facebook access to your phone number and details.
