ARKK is a private, end-to-end encrypted messenger no phone number or email required. No phone number. No email. No account signup. When you first open ARKK, your device generates a 12-word recovery phrase and a pair of cryptographic keys. That phrase is your entire identity it's shown once and never leaves your device. WHY ARKK IS DIFFERENT No phone number, no email, no profile required. Your identity is a cryptographic key, not an account. End-to-end encrypted, always. Messages are sealed on your device with the recipient's key. Our servers only ever relay ciphertext they cannot read. Server-blind by design. Even read receipts and settings ride inside the encryption. Private by default. Read receipts, profile name, and photo are off until you turn them on. Your history stays on your device. Messages persist locally until you delete them. Disappearing messages are an option you enable per chat, not a default. WHO IT'S FOR ARKK is for anyone who wants their private conversations to stay private including journalists, professionals, and privacy-conscious users who prefer not to link a phone number to their communications. WHAT ARKK IS HONEST ABOUT Encryption ends where your screen begins: ARKK can't protect a message on an unlocked or compromised device. A server necessarily sees that ciphertext was routed never its content. ARKK keeps private conversations private. Built by Genroar.
