With these updates, none of that is changing. We also can’t see your shared location and we don’t share your contacts with Facebook. It’s why we don’t keep logs of who everyone’s messaging or calling. This means we will always protect your personal conversations with end-to-end encryption, so that neither WhatsApp nor Facebook can see these private messages. WhatsApp was built on a simple idea: what you share with your friends and family stays between you. There's been a lot of misinformation causing concern and we want to help everyone understand our principles and the facts. We’ve heard from so many people how much confusion there is around our recent update.
Send a million messages a day to your friends for free! WhatsApp uses your Internet connection: 3G/EDGE or Wi-Fi when available.
WhatsApp is also available for iPhone / iOS, Windows and Mac PCs. In addition to basic messaging WhatsApp users can create groups, send each other unlimited images, video and audio media messages. WhatsApp is a cross-platform messaging service that uses the same internet data plan you use for email and web browsing, there is no cost to message and stay in touch with your friends.
