Encrypted messenger · no phone number

An encrypted messenger that never asks who you are.

No phone number. No email. No account. Your identity is a 12-word recovery phrase that lives only on your device, and everything you send is end-to-end encrypted, always.

Built by Genroar in Dubai. No trackers, no analytics, no third-party code.

What makes ARKK different

  • No phone number, no email

    You're a cryptographic key, not a profile. Nothing links your account to who you are.

  • End-to-end encrypted, always

    libsodium public-key cryptography. Keys are generated and stored only on your device, never on a server.

  • Server-blind by design

    Even read receipts and settings ride inside the encryption. The server only ever handles ciphertext.

  • Private by default

    Nothing about your behavior leaves your device unless you turn it on. Read receipts and notifications ship off.

See ARKK

Calm to use. Serious underneath.

Your conversations, your identity, your privacy controls, the whole app is built around one idea: nothing about you leaves your device unless you say so.

Your identity

Your whole identity is twelve words.

When you first open ARKK, your device generates a 12-word recovery phrase and a pair of cryptographic keys. The phrase is the master key to your identity. It's shown once, and it never leaves your device.

We can't reset it, email it to you, or hand it to anyone, because we never had it. There is no account to recover.

In the app, this screen blocks screenshots and appears exactly once.

The design

Privacy that comes from the architecture, not a promise.

ARKK is built so that the people who run the service can't read what passes through it. Everything below is a consequence of taking that seriously.

  1. Identity without a name

    No sign-up. Your device makes a keypair; the public half registers under a short fingerprint, your ARKK ID. The private half stays in your phone's hardware-backed keychain. You trade fingerprints with people you want to talk to. That's the entire identity model.

  2. Encrypted before it leaves

    Messages are sealed on your device with the recipient's public key. The server relays ciphertext it cannot open and deletes it once delivered. There is no key escrow and no master key.

  3. Even the settings are encrypted

    Control messages, read receipts, a disappearing-timer change, travel inside the same encrypted envelope as your words. The server can't tell a setting change from a sentence.

Straight answers

What ARKK is, and what it isn't.

A tool for protecting private conversations deserves honest marketing. Here's the line, plainly.

What ARKK does

  • Keeps your messages on your device by default, your history is yours to keep.
  • Lets you turn on disappearing messages per chat (a 30-second timer), off by default and symmetric for both people.
  • Encrypts every message end-to-end with keys only your devices hold.
  • Keeps read receipts, profile name, and photo off by default and on-device.
  • Protects people who can't safely tie a phone number to their identity, journalists, activists, sources.

What ARKK doesn't claim

  • It can't hide the fact that a message was routed. A server necessarily sees ciphertext, timing, and size, never content.
  • It can't protect a message once it's on a compromised or unlocked device. Encryption ends where your screen begins.
  • It isn't about erasing evidence or evading anyone, it's about keeping private conversations private.
  • Voice calls are coming soon; today ARKK is messaging, attachments, and voice notes.

Refuge for what's private.

A calm place for the conversations that matter, protected by the way it's built, not by a promise. ARKK is in active development.
