Readable information stays on offline devices. Only encrypted data ever crosses the internet.
AirGap encrypts your message on an offline Vault Phone before anything is transferred. Your online Courier Phone only photographs, carries and sends encrypted QR data it cannot read.
Your access code can be used once. The readable code is not stored by the licensing database.
After a valid activation request, your signed AirGap activation QR appears here automatically.
Follow one piece of information from readable text to encrypted QR, across the internet, and back to readable text — only on offline devices.
The internet can carry the package.
It never needs to see what is inside.
A source hands over evidence that could end a career — theirs, or someone else's. The story can't leak before it's published, and the source can't be traced. The message travels as a locked envelope through an app neither of them has to trust.
Acquisition documents move between two people who've never met in person for this deal. A single leak moves markets. The Vault Phone holds the terms; the everyday phone just carries a picture neither the bank nor the inbox can read.
Confidential evidence needs to reach opposing counsel without ever sitting on a mail server. Privilege depends on it staying private. AirGap keeps the content off every server the email would normally pass through.
A wallet recovery phrase is the one string of words that must never exist on a device that's ever been online. Not in a note. Not in a photo. Not in a chat backup. The Vault Phone is the only place it's allowed to live.
Readable content enters online infrastructure and systems you do not control.
Only encrypted data travels online. Readable content stays offline.
Clear claims build trust. Here's exactly what AirGap does — and doesn't — defend against.
Signal is excellent for everyday private messaging. It protects your messages while your device stays online — fast, convenient, built for constant conversation.
Every message means picking up a second phone, scanning a code, sending a photo. There's no getting around that extra step.
AirGap keeps your keys on a phone that never goes online. It is not more convenient, and it is not for every message.
For the handful of messages where a leak would actually hurt you, a few extra seconds is a fair price for keys that were never reachable over a network in the first place.
It takes more effort than normal messaging.
The current version is focused on text communication. Support for larger files and images is part of the future direction.
Both users need a Vault Phone.
If you lose the Vault Phone, recovery must be handled carefully.
The encrypted image can remain in chat history, but it stays unreadable.
AirGap keeps readable information on offline devices and uses the internet only to move encrypted data.
