STORAGE

SteCloud

Cloud storage that's actually yours — your files live on hardware the owner controls, not in a stranger's datacenter, with quotas set by a person, not a price page.

  • Self-hosted — real disks, real ownership
  • Per-user quotas
  • Wired into every Ste app

BUILT PARANOID.

Sealed shut.

Signed packages. End-to-end encryption. Hardware the owner controls.

Quiet. Private. Yours.

🔐

End-to-end encrypted

DM encryption keys are generated on your device and never leave it. Not even the server can read your messages.

📦

Signed packages

Every app ships as a signed, encrypted package. If a single byte is tampered with, it refuses to run.

🏠

Your hardware, your data

Storage lives on hardware the owner controls — not rented racks. No data mining, no ads, no trackers.

UP AND RUNNING
IN THREE STEPS.

  1. 01

    Install SteManager

    One small launcher — the only thing you ever install. Built in Rust, light on RAM, no bloat.

  2. 02

    Sign in once

    One account unlocks the whole ecosystem. No per-app sign-ups, no browser tabs, no password zoo.

  3. 03

    Run anything

    Apps arrive as signed, encrypted packages — verified in memory, launched instantly, always up to date.

UNDER THE HOOD.

No marketing fog — this is literally how it's built.

🦀 Native Rust shell

The launcher is a native Rust app, not an Electron clone for every product. Apps run as lightweight web modules inside one shell.

📦 .ste cartridges

Every app ships as a .ste package — AES-256-GCM encrypted, Ed25519 signed, bound to your machine. Change one byte and it refuses to run.

🔐 Real end-to-end encryption

DMs use device-generated keys (ECDH P-256 → AES-GCM). Keys never leave your device — the server physically cannot read your messages.

🏠 Self-hosted cloud

SteCloud runs on real hardware the owner controls, reached through an encrypted tunnel — no open ports, no rented racks, no data mining.

🤖 Server-side AI

AI agents call the models through our node — provider keys never touch your device, and usage is metered per account. No key leaks, no surprise bills.

🚫 Zero tracking

No ads, no analytics SDKs, no behavioral profiles. The business model is the product, not you.

QUESTIONS, ANSWERED.

Is it free?

The beta is free. One installer, the whole ecosystem. If paid tiers ever exist, privacy will never be the paywall.

What platforms does it run on?

Windows on ARM (Snapdragon) today. More platforms are on the way — the server side already runs on Linux/ARM.

Can anyone sign up right now?

It's an invite-provisioned beta — you can install the launcher, but accounts are issued personally while the network grows. Public sign-ups are on the roadmap.

What exactly is a .ste package?

A sealed app cartridge: encrypted (AES-256-GCM), signed (Ed25519) and bound to your machine. The launcher verifies and decrypts it in memory — tampered or copied packages are useless bricks.

Where does my data actually live?

Chats sync through an encrypted backend with row-level isolation; E2EE DM content is unreadable by any server. Files live on the SteCloud node — physical hardware the owner controls, not a hyperscaler bucket.

Who builds this?

One person, end to end — design, code, crypto, servers. That's not a weakness; it's why there's no growth team trying to monetize your attention.

Big platforms rent you convenience and keep your data as the payment. Stenuero is built the other way around — one independent ecosystem where the keys stay on your device, the files stay on real hardware, and nothing about you is for sale.

GET STENUERO.

Free. One installer, the whole ecosystem.
