Conversations that stay between you.

Chats, calls and photos are encrypted right on your phone. We can’t read them — even if we wanted to. And you don’t need a phone number to sign up.

Features

Why GChat?

Everything you expect from a messenger. Nothing worth hiding.

Always encrypted

Every message, call and attachment is encrypted on your device. There is nothing to turn on.

No phone number

Sign up with a username. To restore your account you use one secret word, not a SIM card.

Voice and video calls

Calls get the same protection as your chats.

Stories and video notes

Share moments with your contacts. Video notes and voice messages work the way you’re used to.

Groups and channels

Talk with friends in groups, or run your own channel for subscribers.

You’re in control

Strangers land in Requests, anyone can be blocked, and deleting your account takes a couple of taps.

How it works

Only you hold the keys.

Encryption happens on your phone before a message ever leaves it. Our server only carries a sealed envelope — it has no way to open it.

Animation: you type “Hello”, your phone locks the message and turns it into random-looking characters. That ciphertext passes through the server — the server sees only that. On Anna’s phone it turns back into “Hello”.
STEP 01

Keys are made on your phone

On first launch the app generates your personal keys. The secret half never leaves the device.

STEP 02

A secure introduction

When you message someone new, your phones agree on a shared secret. The server takes no part in it.

STEP 03

A new key for every message

Even if one key ever leaked, the rest of the conversation would stay closed.

STEP 04

The server only delivers

It hands over the encrypted message and deletes its copy right away.

What our server sees

Sees

  • Who a message is for
  • When it was delivered
  • The size of the encrypted package

Never sees

  • What your messages say
  • Photos, videos and voice notes
  • What is said on calls

Our principles

We don’t keep what we don’t need.

We don’t read what isn’t ours.

We don’t know what you talk about.

That’s the whole point.

Verify the download

The hash proves the file wasn’t altered in transit. The certificate fingerprint proves we signed it: a fake can’t be signed with our key, even if someone posts a matching hash next to it.
