The update will make it easier for people to make purchases and get help from businesses on the messaging platform, a company spokesperson said on Friday.
It remains up to the user whether or not they want to message with a business on WhatsApp, the spokesperson said.
“The update does not change WhatsApp’s data-sharing practices with Facebook and WhatsApp remains deeply committed to protecting people’s privacy,” the spokesperson added.
The company is communicating directly with users through WhatsApp about the changes so that they can review the new policy over the next month.
Sharing data with Facebook will help “personalisation” of content and the display of relevant advertisements across the group’s multiple social platforms, WhatsApp said in a blog post on January 4. It also enables users to interlink services such as a Facebook Pay account to pay for purchases on the messaging app.
