WhatsApp has updated its privacy policy and terms of service to better integrate with other products and services offered by Facebook. Unlike the release of a new feature or an update that adds new functionality, the instant messaging app has brought the change almost silently earlier this week. It has, however, informed Android and iPhone users through an app notice that emerged on Tuesday. The notice provides a glimpse of the changes WhatsApp has brought to its privacy policy and terms of service. Users have also been provided an option to agree to the update directly from the full-screen notice.
