End-to-end encryption
A protection where only you and your recipient can read the messages, not even the service that carries them.
End-to-end encryption guarantees that only the sender and the recipient can read a message. It is encrypted on your device and decrypted only on the other person's: even the service that carries it has no access. It is a strong protection of privacy, but everything rests on the security of the devices: a hacked phone makes the encryption useless.
