The Truth

Those WhatsApp chats you thought you deleted may not be gone. Chat logs from WhatsApp stay on your phone even after you’ve deleted them, according to new research published by iOS expert Jonathan Zdziarski. “The only way to get rid of them appears to be to delete the app entirely,” Zdziarski added. Created by former Yahoo! employees, WhatsApp Messenger is a messaging app that is used for iPhone, BlackBerry, Android, Windows Phone and Nokia phones.

If you use this app you can chat with friends who have any of these kinds of phones for free and not have to pay for SMS because it uses the internet to send them. It is popular because users can send unlimited text, photo, audio, and video messages.
