SigmaZero
Encrypt and decrypt your files with authenticated sealing. Every operation generates a verifiable receipt.
Open SigmaZero, encrypt a file, download the .sqep — then decrypt it. That's it. You'll see your first receipt immediately.
Do you know what happens
to your data?
The blockchain where every AI judgment is proven.
No account needed. Runs locally. Your data never leaves your device.
You don't know what happens to your data
Today, you trust software with your files. But you have no proof of what actually happened.
No visibility
A file was modified, moved, or accessed? You'll never know unless someone tells you.
Blind trust
Your tools promise security. But there's no way to independently verify that promise.
No audit trail
When something goes wrong, there's no provable record of who did what, and when.
How traceability works
Three simple steps. Every action becomes a verifiable receipt.
1
You act on a file
Encrypt, decrypt, share, archive — any action you take on your data.
2
A receipt is generated
A SHA-256 cryptographic receipt is created automatically — timestamped, signed, immutable.
3
You can verify anytime
The receipt chain is mathematically verifiable. No trust in us required — just check the math.
Everything you need to prove it
Traceability backed by real cryptography. Not promises — proof.
Complete traceability
Every action produces a receipt linked to the previous one — an unforgeable chain from the very first operation to the latest.
Sovereign encryption
Post-quantum encryption (ML-KEM-768) + ChaCha20-Poly1305. Your files stay private — today and tomorrow.
100% offline
Everything runs on your device. No cloud, no server, no third party. Your data never leaves.
AI that explains itself
Quaggy is a deterministic AI that logs every decision as a receipt. You see what it did, why, and can verify it.
Open standard
SQEP-Zero is a frozen, public standard. 10 principles. Anyone can verify. No vendor lock-in.
You stay in control
Human-in-the-loop by design. The system helps — you decide.
Your tools
Each app generates receipts. Together, they give you full traceability.
QSeed
Video player with real-time perceptual enhancement — sharpness, stability, metrics.
Quaggy
AI assistant where every decision is a receipt. Ask questions, run tools — everything is traced.
Zoe
Orchestrator that coordinates all agents with safety guardrails and full context memory.
FAQ
What's the fastest way to try it?
What exactly is a cryptographic receipt?
A SHA-256 hash that records what happened, when, and by whom. Each receipt links to the previous one, forming an unforgeable chain.
Do you store my files or keys?
No. Everything runs locally on your device. We never see your files, your keys, or your data.
How is this different from a regular encrypted ZIP?
A ZIP encrypts. SQEP-Zero encrypts AND traces. Every operation produces a verifiable receipt in an immutable chain — that's the traceability difference.
Is a desktop app coming?
Yes. Web tools are live now. SigmaZero Desktop will extend full offline control with the same traceability.
Why "post-quantum" encryption?
ML-KEM-768 (NIST FIPS 203) protects your data against future quantum computers. Your files encrypted today stay safe tomorrow.
