At that time, the number of WhatsApp users was one billion and they were given the option for 30 days to prevent their data from being shared to some extent. Within a month, the data of those who opted for this option could not be shared to any extent with Facebook, this feature is no longer available in the app settings, but you can find out about it from the request account info. However, since then, user data has been shared with Facebook.
According to the company, it collects customer details to provide better services to customers. WhatsApp is still sharing account information with Facebook, such as phone numbers, how long the app has been used, and how often. Other details such as IP address, operating system, browser details, battery health information, app version, mobile network, language, and time zone are also shared with Facebook.
As far as the collection of transaction and payment data, cookies, and location information are concerned, this information is already given to the WhatsApp users who go to Facebook. According to experts, WhatsApp best protects the privacy of users when it comes to message content, but it seems that privacy is not important in the eyes of the company.
Facebook bought WhatsApp in 2014 and said at the time that WhatsApp and Messenger would act as standalone apps. The gradual integration of WhatsApp into Facebook services has been controversial within the company, with WhatsApp founders Brian Acton and John Kom bidding farewell to the company in 2017 and 2018. A few months later, Brian Acton joined the team that founded another messaging app, Signal.
The company maintained the open-source protocol of the signal after it was developed and it also has end-to-end encryption like WhatsApp. The new policy will not change the behavior of the messaging service, but it is important because consumers will know that the company has provided opt-out options for so many years, which will no longer be the case. At the moment, users are reacting strongly to data sharing and are afraid of what is still happening to them, just because they don't know it.
