WhatsApp Messenger

WhatsApp Messenger lets users start video calls and send encrypted text messages, videos, photos, and audio messages to one or many people. Messages can only be sent to other smartphone users who also have WhatsApp. The app checks your phone's address book for WhatsApp users and connects you automatically. It also encourages you to urge friends not using the app to sign up. The app store rates the app 4+, but its license agreement requires users to be 13 or older, and location-sharing makes it most appropriate for older teens. A new two-step verification feature uses a PIN for added account security. The app shares data with parent company Facebook, but users can opt out of this upon agreeing to the terms of use. Once users have agreed, however, the ability to opt out goes away. Users also have the option of sharing their location with those they're chatting with in the Live Location feature. Read the app's privacy policy to find out more about the types of information collected and shared.
