Nitro Messenger vs FAAB

Nitro is a private messenger built on a simple promise: the server cannot read your messages. Content is end-to-end encrypted with a post-quantum hybrid ratchet, so your conversations stay yours — even against tomorrow's computers. WHY NITRO • End-to-end encrypted messages, calls and media — keys live only on your device. • Post-quantum hybrid encryption, not just classic crypto. • The server is a "dumb carrier": it routes opaque, encrypted envelopes and never sees content. • No ads. No trackers. No third-party analytics. Your address book is never uploaded. • Your identity is a @username — your phone number is never shown to anyone. FEATURES • 1:1 chat with delivery receipts. • Photo sharing — images are encrypted on-device before they ever leave. • Voice & video calls with the native call experience (CallKit). • Group chats. • On-device, encrypted history — losing the server never loses your messages. • App lock with Face ID. PRIVACY YOU CAN VERIFY Every chat shows an encryption indicator, and you can confirm a contact face-to-face with a safety number. Delete your account anytime from Settings — your identity and history are wiped from the device. Nitro is single-device by design: no desktop or multi-device surface to attack.

FAAB is a quantum-secured messenger from FAAB Group Inc.: direct messages, group chats, voice and video calls, and a sealed vault for your files. Built so the servers that relay your conversations learn as little as possible, and honest about where that protection stops. QUANTUM SECURED • Direct messages between two people are end-to-end encrypted with post-quantum keys that are agreed between the two phones and keep moving as you talk. The servers relay envelopes they cannot open: text, photos, videos, voice notes, files, replies, reactions, edits and deletions alike. • Voice and video calls, one-to-one and in groups of up to 32, are end-to-end encrypted with a key that reaches each person inside their own encrypted conversation. The server still learns who called whom, when, and whether it was voice or video. • Your keys are born on your phone, mixed with quantum-origin randomness captured during sign-up, and your private keys never leave it. FAAB shows you a Key Birth Certificate. FAAB QUANTUM SECURE VAULT Keep photos, videos and files sealed on your phone, each under its own key. Sort them into folders, open them in the iPhone's own viewers, and share one with a link you can turn off at any time. A link opens only inside FAAB, after the person who shared it is added to your contacts. SECURE CLOUD Keep your account, contacts, chats and vault safe if you lose or change your phone. Everything is sealed on this phone first — FAAB can't open it. A new phone signed in to the same Apple account restores it with one tap, and you can add an optional recovery key. WHAT IS NOT END-TO-END • Group chats are encrypted in transit to the server, not end to end. The server stores group history and can read it. Every group in the app is labelled this way. • Even for direct messages, the server sees metadata: who talks to whom, when, and how much. FINDING PEOPLE Choose an @handle. Add people by their @handle, by scanning the QR code on their phone, or from the link it carries; after a scan, FAAB refuses a changed key for that contact instead of silently accepting it. FAAB never reads your address book. ON YOUR PHONE • App lock with a 6-digit PIN and Face ID or Touch ID. • A privacy cover hides the app in the app switcher. • Notifications don't show message text unless you turn that on. • Link previews are fetched by your phone, and you can turn them off. • Share from any app: in Photos, Files or anywhere else, Share › FAAB sends to your chats or saves to your vault. NO ADS, NO TRACKERS No advertising, no analytics and no tracking SDKs. OPEN TO EVERYONE FAAB is free and open to anyone: no invitation, no waiting list, no organization to belong to. INDEPENDENT AUDIT FAAB has not had an independent security audit yet. Until it has, please don't rely on it where a failure could put someone at risk. Delete your account: Settings › Delete all data.
