Vutalk - Encrypted Chat

Vutalk is an end-to-end encrypted messenger for people who would rather not hand over a phone number or an email address.

You create an account without either. The app gives you an Account ID and a recovery key, and nothing else is needed. Other people reach you through the username you pick, or the QR code that goes with it. Your address book is never uploaded.

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

No number, no email — Create an account with no phone number and no email address. Keep your Account ID and recovery key: they are how you get back in.

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, with voice or video.

Photos, video, and files — Send images, videos, documents, and voice messages through the same encrypted channel.

Wallet — Receive, send, and view history from Settings. The keys stay on your device.

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.

Accounts created with an email address in an earlier version keep signing in with that address.
