Vutalk is an end-to-end encrypted messenger for people who would rather not hand over their phone number. You sign up with an email address. There is no phone number, no SMS code, and no address book upload. Other people reach you through the username you pick, or the QR code that goes with it, and nothing else. Messages, calls, and files are encrypted on your device before they leave it, and the keys stay on your devices. Nobody in between can read them, and neither can we. FEATURES Email sign-up Create an account with an email address. A phone number is never requested. Username and QR code Share a username, or let someone scan your code. Your contacts are never uploaded or matched against our servers. Encrypted messaging One-to-one and group conversations, end-to-end encrypted by default. Voice and video calls Encrypted calls, one-to-one and in groups. Photos, video, and files Send images, videos, documents, and voice messages through the same encrypted channel. Disappearing messages Choose how long a conversation keeps its history, from seconds to weeks. Free, with nothing to buy No subscriptions, no in-app purchases, and no advertising. Modern cryptography Key agreement uses X3DH, and every message advances a Double Ratchet, so earlier messages stay protected even if a device is compromised later.
