WhatsApp claims the policy update will not affect the privacy of your messages with friends or family in any way. Since personal messages are protected by end-to-end encryption, neither WhatsApp nor Facebook can read your messages or see your shared location. Instead, the new policy update only includes changes related to messaging a business, a feature that is optional.
If you choose to use WhatsApp’s commerce features, your shopping activity could be used to personalize your experience and the ads that are shown to you on Facebook and Instagram. Facebook may also use the way you interact with ads that have a button to message a business using WhatsApp to personalize the ads you see.
Some large businesses need to use hosting services to manage their communication. Which is why we’re giving businesses the option to use secure hosting services from Facebook to manage WhatsApp chats with their customers, answer questions, and send helpful information like purchase receipts. But whether you communicate with a business by phone, email, or WhatsApp, it can see what you’re saying and may use that information for its own marketing purposes, which may include advertising on Facebook.
If you do not want Facebook to access any of your WhatsApp, the only option is to switch to a different messaging app. The two of the best options to consider right now are Signal and Telegram. While Telegram isn’t nearly as secure as WhatsApp, Signal offers pretty much all the features that make WhatsApp so popular – including the same end-to-end encryption protocol.
