We limit the information we share with Facebook in important ways. For example, we will always protect your personal conversations with end-to-end encryption, so that neither WhatsApp nor Facebook can see these private messages. We don’t keep logs of who everyone’s messaging or calling and can’t see your shared location so we cannot and do not share this with Facebook. We need your contacts to provide the service, but don’t share your contacts with Facebook. You can learn more about some of these limitations here.
