Post-quantum end-to-end encrypted direct messages and calls, a sealed vault for your files, keys born on your phone. No ads, no trackers.
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. Signing up takes a phone number: FAAB sends it a one-time code by text or by a call, and ties it to your account as a keyed hash (never the number itself) so you can restore your account on a new phone. No one can find you by 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.

Calls connect more reliably.
When two people call each other at the same moment, FAAB now joins them in one call instead of ringing a second one.
The first call to someone you have just added connects on the first try.
Your phone rings more reliably: FAAB keeps its connection to Apple's push service up to date, still rings when your iPhone's clock is off, shows a call that came too late as missed, and tells you when a Focus silenced a call.
People who add you are saved on your phone, and the Calls tab shows their name instead of "Someone".
Louder ringback while the other phone rings, and FAAB's own ringtones — choose Silk, Pulse or your iPhone ringtone in Settings › Notifications.
FAAB tells you when a newer version is in the App Store.
