Privacy
is Freedom.

This thing disappears. You use it and it’s like you were never there. It works anywhere, leaves nothing, and controls exactly who can access it.

Mobility

• Runs from a flash drive on any computer — nothing installed, nothing left behind
• Pocket sized — take it anywhere, works on any machine you sit down at

Privacy by design

• Boots its own operating system — the computer you plug into never sees what you’re doing
• Remove the drive — the session ends, the work disappears, you were never there
• Encrypted backup — your data backs up to physical storage only, never a server

Access control

• Multiple users — each person has their own isolated space with admin controls
• Guest mode — full access to AI and knowledge, nothing written, everything wiped on exit

We thought about your threats — the casual snooper, the sophisticated attacker, the physical seizure, the digital surveillance, the hardware hack. Every angle is covered and most of them result in the data destroying itself. Stella started with the threat model and built backwards.

If the device is lost or seized

• Full disk encryption — without the passphrase, the drive is unreadable on any machine
• Dead man switch — three failed login attempts destroys the drive permanently and irreversibly
• Panic passphrase — a second secret phrase triggers silent destruction behind a fake loading screen
• Forensic recovery — deleted files are gone forever via seven-pass overwriting
• File tripwires — any unauthorized browsing or interaction with the system files destroys the keys instantly

To prevent tracking

• Internet traffic — your browser, research, and payment traffic cannot be linked to each other because they are all isolated
• Browser fingerprinting fully disabled — no website can identify your device, location, or behavior
• Session data wiped on browser close — nothing left on the machine you were using
• No accounts — no registration, no license server, no telemetry, no way to phone home

To prevent hacks and attacks

• Keylogger detection — scans for hardware recording devices before you type anything
• On-screen keyboard — appears at a random position every boot, defeats camera replay attacks
• Prompt injection detection — every AI input scanned for known manipulation attacks
• Chamber — three independent filters on everything that enters the system
• Image and audio sanitization — all metadata stripped, steganographic payloads destroyed
• BIOS integrity check — verifies the machine hasn’t been tampered with at every boot
• Host fingerprinting — rejects any unregistered machine before it can access your data

To protect your data

• Hardware write-protected core — the base system cannot be modified by any process at runtime
• Three-zone architecture — your sensitive data and network activity are separated at the OS level, they cannot touch each other
• Security log — every security event logged in a tamper-evident chain

A complete working environment that never, under any circumstance, reaches out to anyone.

What it does

• Fully offline — every single feature works without an internet connection
• Built-in apps — Chat, Notes, Files, Airdrop, Browser, Payment Terminal, and Dev Workspace all included
• Local AI — your conversations, questions, and documents never leave the device
• Brain — a private knowledge base that learns what you feed it, never shared, never synced
• Mesh Network — encrypted messaging between devices without internet or cell service

What it never does

• Never creates an account — no registration, no license server, no check-in with anyone
• Never phones home — no telemetry, no usage data, no remote kill switch
• Never touches a server — your data backs up to physical storage only
