Messaging with no server in between.

Kyberspace connects your phone directly to the people you know. No account, no cloud, no copy of your conversations anywhere but your device.

How it works

Private by architecture, not by promise.

01NO SERVERS

Your messages never touch a server.

Phone to phone, directly. No account, no cloud — the only copy lives on your device.

Peer-to-peerOn-device storage

Kyberspace

There is no server.

Other apps say your messages are private, or encrypted — but they still pass through a company’s servers on the way. This app has no servers. Messages go straight from your phone to theirs.

01

There was no sign-up

You never made an account or picked a password — the app gave you an address of your own the moment you first opened it. There’s nothing to remember, and no company holding it for you.

02

Nobody can look you up

You can’t be found by searching, the way you might look someone up on other apps. The only people who can reach you are ones you’ve personally shown your glyph to.

03

A Joint is live only

In a Joint, only the people there at that moment see what you send. Miss it, and it’s gone — nothing is saved for later. A Kyber Link is different: it’ll wait for you to come back online, but only ever on your two phones, not on a server.

04

This device holds the only copy

Your conversations and your address live on this phone, and nowhere else. Lose it without a backup, and they’re gone for good — there’s no support line to call for a new one.

02POST-QUANTUM

Encryption built to outlast quantum computers.

Keys are made on your phone. What’s recorded today stays unreadable tomorrow.

Keys never leave your phoneQuantum-resistant

03NO STRANGERS

Only people you’ve met can reach you.

No phone number, no search. Every contact starts with a glyph swapped in person.

Beyond one-to-one

Groups and files, still nothing in the middle.

Kyber Joint

Group chat

Group chats that leave no trace.

Everyone online hears it together. Nothing is stored — not on a server, not for later.

Kyber Hub

File sharing

Share files straight off your phone.

You choose who can fetch. They take a copy directly from you — no upload, no cloud drive.

Meet someone. Swap a glyph. Talk.
