How it works
Three simple steps to completely private communication.
Create a room
Start a room in one tap. No signup, no setup.
Share the password
Send it to whoever you want in the room — 2 people or a group.
Talk, then it's gone
Message and call freely. Delete the room and everything in it disappears for good.
Designed for privacy
Built from the ground up without central data collection.
Password-protected rooms
Only people with the password can enter. No public links, no searchable directory.
Client-side end-to-end encryption
Messages and calls are encrypted on your device before they ever leave it.
No personal information required
No email, no phone number, no account to create or manage.
Group and one-on-one
Rooms work the same whether it's a private conversation or a whole group.
Voice calls, built in
Talk directly, peer-to-peer, without switching apps.
Permanent deletion
When you delete a chat, it's actually gone — not archived, not recoverable.
Why Kyrum exists
Every other messaging app asks who you are before it lets you talk. Kyrum doesn't ask. Your room, your key, your conversation — nothing about you is collected, stored, or left behind. Kyrum is built from exactly that: a key, and a room. Nothing more is needed, and nothing more is taken.
