Locked on your phone
Before a message leaves your device, Pigeon scrambles it with a key that only you and the other person have.
Security
Every message, photo, and call on Pigeon is locked on your device before it goes anywhere. Only the people you’re talking to can open it. Not us, and not anyone in between.
How it works
This happens automatically. There’s no setting to turn on and nothing to manage.
Before a message leaves your device, Pigeon scrambles it with a key that only you and the other person have.
Our servers, or nearby phones over Bluetooth, pass along a sealed envelope. Nobody along the way can open it.
Their device unlocks it. If anything looks wrong, Pigeon refuses to show the message rather than guess.
Honest about it
Running a messenger means handling a little information. Here’s exactly where the line is.
What you write, the photos and files you share, and what you say on calls. We don’t hold a key that could open them.
Which account a sealed envelope is going to, and when it was sent. That’s what a mail carrier needs to know, and nothing more.
Undelivered envelopes expire. Once your devices pick them up, we have no reason to keep them around.
Nearby
When there’s no internet, Pigeon can pass your message between phones over Bluetooth. It’s locked the exact same way. Phones that help carry it along can’t read it. They just hand it to the next phone.
Nearby reaches people close by, not across town. It isn’t a replacement for calling emergency services.
More protections
Scan a code with a friend to confirm you’re really talking to them, and not an impostor.
Require your face, fingerprint, or PIN to open Pigeon, even when your phone is unlocked.
Set a chat to clear itself after a while. Free for everyone, in every chat.
Backups are locked with a passphrase only you know. Lose it, and even we can’t open them.
Alerts just say “New message.” Your words never pass through Apple or Google.
Photos, voice notes, and documents are encrypted before upload, just like your messages.
Protocols, the server’s view, how the Bluetooth mesh routes, our threat model, and what isn’t finished yet.
