According to WhatsApp, there's been "a lot of misinformation" leading to concern about the update. WhatsApp clarifies that the update does not expand its ability to share data with Facebook and is instead simply providing further transparency about how user data is collected and shared when using a new tool for messaging a business on WhatsApp.
With these updates, none of that is changing. Instead, the update includes new options people will have to message a business on WhatsApp, and provides further transparency about how we collect and use data. While not everyone shops with a business on WhatsApp today, we think that more people will choose to do so in the future and it's important people are aware of these services. This update does not expand our ability to share data with Facebook.
WhatsApp is now planning to move back the date on which people will need to review and accept the new terms and conditions to use the WhatsApp app, and no accounts will be deleted or suspended on February 8, which was the original date WhatsApp planned to enact the new policy. WhatsApp will now "do a lot more" to clear up misinformation about how privacy and security works, and then will make the new business options available on May 15.
WhatsApp has in fact shared some user information with Facebook since 2016, such as phone number, but chat messages and phone calls remain private and protected with end-to-end encryption.
