Your data is untouchable
Every item encrypted with its own key. Every attack slowed by non-parallelizable puzzles. We can't read your data — and neither can anyone else.
Multi-layer protection
Every security decision in FoxVault is designed to minimize trust and maximize isolation.
Encryption at every level
Your password never leaves your device. Every vault has its own key. Every item within has its own unique key. We can't decrypt anything — even if we wanted to.
Hardened against modern attacks
Time-lock puzzles make each item cost 200ms to crack — and that cost can't be reduced with more hardware. Your vault size makes it harder. The more items you have, the safer you are.
Defense in depth
Keys live in an isolated memory space immune to browser attacks. Sensitive items need a PIN or hardware key. Every access is logged in a tamper-proof chain. We detect if anyone modifies your data on the server.
5 layers of protection
Every password guess costs an attacker 101 seconds of sequential computation. Throwing more hardware at it doesn't help.

Security beyond encryption
Encryption is just the start. Here's how we protect your privacy at every level.
No tracking
No third-party analytics, no tracking pixels, no fingerprinting. We don't know how you use FoxVault — and we don't want to.
Nothing on our servers
Our servers only store encrypted blobs. No plaintext passwords, keys, or personal data ever touches our infrastructure.
Minimal data
We store your email for sign-in and your encrypted vault. That's it. No names, no addresses, no payment info unless you upgrade.
Works offline
Your vault is cached encrypted on your device. Access passwords and 2FA codes even without internet — it syncs when you reconnect.
Auto-lock
Your vault locks automatically after inactivity. All encryption keys are wiped from memory — a page reload requires re-authentication.
Account isolation
Every user's data is isolated via database row-level security. Audit chain entries are append-only — no UPDATE or DELETE policies exist.
Full Security Model
Our complete security model documentation covers the cryptographic protocol, threat model, key lifecycle, and architectural decisions in detail.
