End-to-end encrypted messenger
Vutalk encrypts every message and call on your device. There is no number and no email address to hand over — and the only way anyone finds you is a username you chose to share.
Free · No ads · iOS 18 or later
Vutalk is built so that the server never holds anything worth reading: no keys, no phone numbers, no address books. This is what that looks like.
Messages, calls, attachments, group names and member lists are encrypted on your phone. Our servers relay ciphertext and hold no key — so there is nothing for us, or for anyone who compels us, to read.

Most messengers make a phone number the price of entry, then turn it into your identity. Vutalk asks for neither a number nor an email address: you get an Account ID and a recovery key, and the only thing anyone can look you up by is a username you chose to share.

The only way to be found
vutalk.com/u/mayaNo upload, no matching — not on our servers, not in an enclave, not at all. There is no setting to turn off, because there is nothing to turn off. An account can only be reached by someone who was handed its username.

Since the first launch, and by design
Encryption only helps if the key belongs to the person you think it does. Every conversation has a safety number derived from both identity keys. Compare it once, in person or over another channel, and Vutalk will stop and warn you if it ever changes.
Key transparency runs underneath: the mapping from an account to its public keys is published in an append-only log, so a server handing out a substituted key leaves permanent evidence.
Not one label but five mechanisms, each doing one job. We use published, peer-reviewed designs rather than anything of our own invention, and the security page also says what each layer does not protect.
Set against a typical messenger that registers by phone number.
| Typical messenger | Vutalk | |
|---|---|---|
| Phone number | Required to sign up | Never |
| Address book upload | Uploaded for matching | Never |
| Contact matching | On by default | Never |
| Searchable by number | Anyone who has it | Never |
| Ads and third-party trackers | Common | Never |
One-to-one and group conversations, end-to-end encrypted by default. Replies, reactions and mentions included.
Share a username, or let someone scan your code. Change it whenever you like; nobody can look you up any other way.
Images, videos, documents and voice messages travel through the same encrypted channel as your text.
Choose how long a conversation keeps its history, from seconds to weeks. It applies on both sides.
No subscriptions, no in-app purchases and no advertising. There is nothing to upgrade to.
Every conversation has a safety number you can compare, and key transparency means a substituted key leaves permanent evidence.
Voice and video, one-to-one and in groups. The same keys as your messages; the same rule that our servers see nothing.
One-to-one and group calls, encrypted on your device before a single frame leaves it.
Incoming calls ring on the lock screen with Answer and Decline, and keep ringing until the caller hangs up.
When two devices cannot connect directly, a relay forwards encrypted packets. It cannot decode audio or video.
Calls you miss while the app is closed show up as missed calls in the conversation.
Install it, pick a username, and share it only with the people you want to hear from.
