When you open WhatsApp you get a screen for you to accept the new terms and conditions, at the moment it is not mandatory to accept them, but as of February 8 you will not be able to use it if you do not accept the terms, so we must know about these new interesting changes that happen in This platform, although the screen to accept only has 3 updates, the issue is deeper than it seems.
Basically will happen with this change is that it will now be mandatory to share your WhatsApp data with Facebook, but we must not confuse your data with your chats, the chats will continue to be encrypted which means that no one except the sender and receiver of the message will have access to it, or at least that's what they say from the company.
What if you are going to share with Facebook is information such as your phone number, your name and how you interact with other users of the platform, including companies, they will also identify your mobile device with your IP address to know if you use other devices in your Wi-Fi network and thus identify what type of user you are, now, why do they want to identify you? , to sell you products, to send you advertising and to be effective, remember that the way Facebook has to generate money is the sale of advertising ads.In theory they will not offer you advertisements regarding your conversations, but they will create profiles with all the additional information that they will now have, in addition it will also allow some WhatsApp conversations to be managed from the Facebook profile, the idea is to integrate the two platforms for the user's convenience but more so that the advertising of companies and services is more effective. something in the style of Instagram that merge your chat with Messenger.

They will also monitor WhatsApp payments to know how much and to whom you paid and with that information create a better profile, these real people who want to sell us products are some giants of social networks and advertising now I understand why they have suffered so many antitrust lawsuits in recent months .
