Unfortunately there is nothing you can do to stop WhatsApp from sharing your phone number with Facebook. The messaging application announced that from August 25, 2016, it would share its users’ information with the social network, allowing users until September 25 of the same year to give or deny their consent to carry out the operation. What does that mean? Simply put, if you installed WhatsApp on a new phone number, you cannot prevent the transfer.
There is a way Trick you can exploit: Access Facebook from your phone’s web browser. That means you die Facebook application (or her Lite-Version) cannot be installed on your mobile and therefore it is more cumbersome to move around the Faceboook interface, especially considering that the applications have been developed with mobile interfaces in mind and in this case you will have to use a web version that can be used focused on mouse and keyboard users.
What is the benefit? If it is not installed on your phone as an app, Facebook will not be able to read your phone’s data and you will achieve your goal. For now, the only option for these applications is not to communicate with each other; the social network, WhatsApp and Instagram are three apps that are part of a whole and whose installation and operation involve the exchange of information and data between their users. Always with the excuse of a better user experience.
