Privacy and security are in our DNA
From day one, we have built WhatsApp to help stay in touch with friends, share vital information during natural disasters, put in separate families contact, or search for a better life. Some of the most personal moments were shared on WhatsApp, which is why we built the encryption end-to-end in the most recent versions of our application. When encrypted end-to-end, messages, photos, videos, voice messages, documents and calls can not fall into the wrong hands.
The end-to-end encryption of WhatsApp is available when you and recipients of your messages using the latest versions of our application. Many messaging applications encrypt messages only between you and them, while the end-to-end encryption of WhatsApp ensures that only you and the person you are communicating with can read what is sent, and that there is no one in the middle, even WhatsApp. This is because the messages are protected with a padlock, and only you and your recipient have the special key needed to unlock and read. For added protection, each message has its own lock and its own unique key. All this happens automatically: you do not need to activate any settings or create special secret chat to protect messages.
The WhatsApp calls allow you to talk to friends and family, even if they are in another country. Just like messages, WhatsApp calls are encrypted end-to-end so that WhatsApp and third parties can not hear them.
Messages remain with you
Your posts should remain in your hands. That’s why WhatsApp does not store the messages on our servers once delivered, and, in any case, with encryption, end-to-end WhatsApp and third parties can not read.
Seeing is believing
WhatsApp allows you to verify that the calls you make and messages you send are encrypted end-to-end. Just look for the indicator in the contact info or info group.
