Silence is a feature.

Every serious review asks the same questions. Hush was built to answer all of them — not with a slogan, with architecture.

What is Hush?A private messenger on the open Matrix protocol. End-to-end encrypted, no phone number, and you can run the server yourself.
What does it do?Text, media and bomb messages that self-destruct — all encrypted on your device. And it keeps working with no internet, phone to phone.
Who is it for?Anyone who wants a messenger the server cannot read — from the merely private to journalists, teams and people under real surveillance.
The honest starting point

First question: who are you hiding from?

There is no single "most secure" messenger without a threat model. A journalist, a company and someone facing advanced surveillance each need something different. Hush is built for the hard end of that range — and stays usable for everyone else.

The scorecard

Every question a review asks. Answered.

These are the exact criteria serious reviewers use to rank messengers. A badge that just says "Encrypted Messenger" answers none of them. Hush answers each one.

The honest part: "Open source" does not automatically mean safe. "Swiss HQ" does not mean private. A big AES-256 label on a website settles nothing. What matters is the whole system — and Hush is built to be read as a whole.
✈ Airplane mode? Still talking.

Messages that travel with no internet.

When the network is gone — a protest, a blackout, a border, a dead zone — Hush keeps going. Phones near each other pass end-to-end encrypted messages device to device over Bluetooth and Wi-Fi, then sync to the server only once the internet returns. This is the feature almost nobody else ships.

Honest about the limitsAndroid-first, where the radios allow true background mesh. On iOS it runs in the foreground — we say so, we don't fake it.
How, not just what

The architecture behind the checkmarks.

Live, side by side

What you write. What the server stores.

End-to-end encryption is not the same as HTTPS. With HTTPS the server can still read the plaintext. With Hush the server only ever holds noise — because the keys never leave your device.
