End-to-end encrypted
Private rooms and direct messages are encrypted on your device. The keys belong to you and the people in the room — not to the server, and not to us.

Why Element
Built for trust, not for attention.
No ads, no feed, no engagement tricks. Just a fast, modern messenger where the important things stay obvious: who you're talking to, and where your messages live.
Talk beyond this server
Matrix federates like email does. Your account here can join rooms and message people on thousands of other homeservers — no shared platform required.
Voice and video calls
Call one person or a whole room straight from the app. A relay server runs alongside this homeserver so calls still connect through strict firewalls and mobile networks.
Share anything, up to 500 MB
Photos, video, voice notes and documents up to half a gigabyte each, with inline previews and full searchable history on every device.
Rooms, spaces and threads
Group related rooms into a space, keep tangents in threads, pin what matters and search the lot. It scales from two friends to a whole community.
Open source, top to bottom
The Element app, the Matrix protocol and the server software are all open source. Anyone can read the code, audit the cryptography and run their own.
One network, many homes
Your account lives here. Your conversations go everywhere.
Matrix links independent servers into a single open network — much like email, but for real-time chat. kaira.email is your home server: it holds your account and your keys. From it you can reach anyone else on Matrix, and they can reach you, without either side signing up to the same company.
- You get a real address. Your ID looks like
@you:kaira.email— people can find you from any Matrix app. - No single owner. There is no central company that can switch the network off, change the rules or read the rooms.
- You are never locked in. If you ever move to another server, the network — and the people on it — are still there.

Questions
Good things to know first.
What is Matrix, in one sentence?
Matrix is an open standard for real-time chat, the way SMTP is an open standard for email: independent servers run by different people, all talking to each other. Element is the app you use to reach it, and kaira.email is one of those servers.
Is it really end-to-end encrypted?
Yes, for private rooms and direct messages — Element turns encryption on by default for those, and the keys never leave your devices, so the server stores only ciphertext it cannot read.
Large public rooms are deliberately left unencrypted, on Matrix in general, so that anyone can join and read the history. You can always tell which is which: an encrypted room shows a shield on the composer.
What will my username look like?
Something like @alice:kaira.email. The first part is the name you pick, the second is this server. That full address is what people on any other Matrix server use to find you.
Do I have to install anything?
No. The web app works in any modern browser on a phone, tablet or computer. Installing the Element app is optional — worth it mostly for push notifications and a faster start on mobile.
Can I message people who aren't on kaira.email?
Yes — that's the point of federation. You can message anyone on any Matrix server and join rooms hosted elsewhere, and people elsewhere can do the same with you, using your full @you:kaira.email address.
Does it cost anything?
Creating an account on kaira.email is free.
Where do my messages actually live?
On this server, and on the servers of anyone else in the room — that is how a federated network delivers a message. In an encrypted room every copy is ciphertext, readable only by the devices in the room.
In an unencrypted room, the server operators involved can read the contents, exactly as they can on any other Matrix server. Keep anything sensitive in an encrypted room.
