Contacts, passwords, documents, identities — all sealed behind AES-256-GCM before a single byte reaches any server. Your keys never leave your device. Not even to us.

Zero-Knowledge Architecture
Every encryption operation happens locally. Your keys never leave your device. We built the architecture so that even a court order couldn't produce your plaintext data.
Keys generated locally. Never transmitted. AES-256-GCM encryption before any I/O.
Ciphertext leaves the device. No plaintext. No metadata. Unreadable without your local key.
Opaque blobs in transit and at rest. Zero-knowledge — we physically cannot read your data.

"I rotate API keys across 14 active client projects. Before Vault, I had a spreadsheet that was a liability. Now everything is encrypted locally and I can share individual secrets without ever exposing the full vault."
Marcus Okonkwo
Freelance Backend Engineer
"I was sitting in Tbilisi with sources whose names would end careers — or worse. Vault meant those contacts never touched a server I didn't control. The zero-knowledge sync kept my MacBook and burner phone in sync without a third party knowing either existed."
Selin Çelik
Investigative Journalist
"Our Series A lead asked how we handle sensitive customer data internally. I showed them Vault's architecture diagram. The conversation moved from risk to trust in about four minutes. We closed three weeks later."
