Access from any browser, anywhere
Your vault syncs seamlessly across all your devices — no compromises, no platform lock-in.
All the security of a bank vault, with none of the limitations
No bank hours. No trips downtown. Access your documents from your phone, laptop, or any device—24/7 from anywhere in the world.
Share your will with your attorney, medical records with specialists, or tax docs with your accountant. Instantly. Securely. Revoke access with one click.
Your documents survive fires, floods, earthquakes, and theft. Even if your house burns down or gets robbed, your digital possessions remain safe.
Unlike physical safe deposit boxes that banks can access with a warrant, your encrypted data is mathematically impossible for anyone to read—including us.
Physical safe deposit boxes cost $50-300/year and you can't access them remotely. SeraVault starts free, with premium plans from just $5/month.
Physical boxes are tiny. Store gigabytes of documents, photos, videos, and files. Everything important, all in one secure place.
Traditional encryption (RSA, ECC) will be broken by quantum computers. SeraVault uses ML-KEM-768, a lattice-based algorithm standardized by NIST specifically to resist quantum attacks.
ML-KEM-768 is officially recommended by the U.S. National Institute of Standards and Technology
Your files are encrypted with proven, battle-tested symmetric algorithms. AES-256 remains secure against quantum computers (128-bit effective security via Grover's algorithm)
Your passphrase never leaves your device. Keys are derived using Argon2id with 64 MiB memory cost, providing superior protection against GPU and ASIC attacks
Our code is public on GitHub. Security through transparency, not obscurity

This is the tradeoff of zero-knowledge encryption: we can't reset your passphrase because we don't have access to your keys. That's why we recommend setting up multiple authentication methods (hardware keys, key file backups) and storing your passphrase securely.
No. Mathematically impossible. Your files are encrypted on your device before they reach our servers. We only store encrypted blobs. Even if we were legally required to hand over your data, we cannot decrypt your files — we simply don't have your encryption keys.
Yes. ML-KEM-768 is one of the algorithms standardized by NIST specifically for post-quantum cryptography (FIPS 203). It's based on lattice mathematics that is believed to be resistant to both classical and quantum computer attacks.
Similar concept! Apps like Signal encrypt messages end-to-end. SeraVault does the same for files. The difference: we use post-quantum algorithms (ML-KEM-768) instead of traditional ECC, and we encrypt metadata too.
You can export your encrypted files and private key at any time. You can even run your own server.
Absolutely! Many professionals use SeraVault for client files, contracts, and sensitive business documents. However, we also offer enterprise plans with team management, audit logs, and compliance features. Contact us for details.
We publish a transparency report, but here's the key point: because of our zero-knowledge architecture, even if we were ordered to hand over your files, we cannot provide anything readable. We simply don't have your keys.
Don't! That's the point. Our code is independently auditable—you can verify it yourself. Our encryption is client-side—you can verify we never see your keys. Our architecture is zero-knowledge—mathematically provable that we can't access your data. Trust the math, not the company.
SeraVault is fully cross-platform. Native apps are available for Android, iOS, Windows, macOS, and Linux, and SeraVault works on Chromebooks via the web app and Android app. There is also a web app accessible from any modern browser. Your vault syncs seamlessly and securely across all your devices — the same end-to-end encryption on every platform, with no compromises.
Yes! SeraVault lets you build fully custom encrypted forms — medical history intake, emergency contact sheets, client onboarding, NDA signing, insurance claim workflows, and more. Every field is encrypted end-to-end before it ever leaves the browser. Responses go directly into your encrypted vault, never stored in plaintext on any server.
