01
The server only sees ciphertext
Messages, calls and media leave your device already encrypted. The server just relays them – neither an administrator nor anyone who copies the database can read the contents. Plaintext lives only on your devices.

Nocta carries only ciphertext. Messages, calls, media and even themes — everything stays end-to-end encrypted. Quiet by design, beautiful by choice.

Most messengers make money on you.
Nocta works for you.
02
End-to-end encrypted, forward secret
X3DH + Double Ratchet on every conversation. Each message is sealed with a fresh key – even if one leaks, past and future stay locked.
03
No accounts that aren’t yours
No phone number sold to a broker. No email tied to ads. Identities are device keys; profiles are per-conversation. The graph stops at your contacts list.
04
Composed, not cluttered
Mainstream-messenger clarity, fewer distractions, much better taste. Calls, threads, devices – nothing else competing for your attention. Quiet is a feature too.

What the server sees, vs. what you see.
A live, scripted conversation. The middle column is what travels through Nocta’s servers. The sides are what each device decrypts locally.

For corporationsYour server.
Your server.
Your NoctaCode pool.
For organisations whose conversations must not leave the perimeter: we deploy Nocta on your infrastructure. No third-party clouds on the message path, no outside operator. Nocta Software installs, configures and supports.
On-prem deployment
Your data centre, your VPS, your rack. We ship the images and documentation and help you bring it up. Then everything stays under your control.
Dedicated NoctaCode pool
Your staff’s handles live only inside your instance. Messages between internal devices never leave your network.
A clean line of responsibility
You are the data operator. We are the vendor. That simplifies audits, customer contracts and regulator conversations.
Direct support from Nocta Software
Upgrades, migrations, incident postmortems, custom client builds. Direct line to engineers – no ticket bots.
