In it, WhatsApp says that this sharing of data only applies when you interact with a business on its platform. And more specifically, only businesses that use Facebook’s hosting services. Messages that pass through the service, be they via WhatsApp or other channels, will be visible. This information can then be used to send you personalised ads on Facebook. The company says your chats with these applicable businesses will be clearly labelled.
Beyond that, the company makes its usual assurances that your private chats will remain so. This ranges from your messages or calls, to specific individuals or groups. And it also applies to shared locations. WhatsApp also reassures that it doesn’t keep logs of these conversations, nor does it share them or your contacts with Facebook. (Source: WhatsApp)
