Your most important files — passports, wills, passwords, crypto keys, medical records — deserve better protection than a cloud folder. Store, share, and chat securely with your family or team. Protected by post-quantum encryption that even future computers can't crack.
Tax returns are PDFs. Wills are Word docs. Passwords live in your head or a notes app. Crypto seed phrases sit in a screenshot. Medical records are emailed around. Every one of those files is worth protecting — and right now, most of them aren't.
SeraVault works like a digital lock box you can hand a key to — without ever losing control. A family sharing estate documents. A legal team collaborating on confidential files. A medical practice exchanging patient records. A startup protecting trade secrets. Each person gets their own encrypted access, and you can revoke it instantly with one click.
Message family, your attorney, your CPA — all inside the same encrypted vault. Every message is end-to-end encrypted and quantum-safe. Not even we can read them.
Recipients don't need a paid plan to view files you share with them. Only the file owner uses storage quota.
Change attorneys? Switch accountants? Remove access with one click — no shared passwords to change, no files to re-upload.
Everything you need to keep secure and access anywhere
Store all your passwords, 2FA codes, and security questions safely
Credit cards, bank accounts, and financial documents in one secure place
Seed phrases, private keys, and wallet passwords - never lose access
Passports, IDs, birth certificates, tax returns, and legal papers
Health records, prescriptions, insurance cards, and doctor notes
Developer keys, SSH keys, database passwords, and server access
A full secure vault — files, passwords, notes, cards, chat, and more. All encrypted before it leaves your device.
Message family, colleagues, attorneys, or anyone you've shared files with — all inside the vault, all encrypted. Every message uses the same post-quantum encryption as your files. No third-party apps. No metadata leaks. Not even we can read them.
Store Social Security cards, passports, driver's licenses, birth certificates, immigration papers, military records (DD-214), professional licenses, diplomas, education records, wills & testaments, power of attorney, intellectual property, vehicle titles, and property deeds. Never lose critical documents again.
Store credit cards, bank accounts, investment statements, cryptocurrency wallet seeds, insurance policies (home, auto, life, health), loan documents, safe combinations, and loyalty reward programs. Access when needed, encrypted when not.
Share tax documents with your accountant, medical records with specialists, or legal documents with your attorney. Each person gets their own encrypted access—they don't need a paid plan to view files you share. Revoke anytime with one click.
We can't read your files. Ever. Your data is encrypted on your device before it reaches our servers. Even if our servers were breached, your files stay private.
Unlock with your fingerprint, face ID, or YubiKey hardware key. No need to remember complex passwords. Choose the security level that fits your lifestyle.
Securely store API keys, SSH keys, database credentials, server access, VPN credentials, encryption keys, and 2FA backup codes. Perfect for developers, sysadmins, and IT professionals managing multiple services and environments.
Keep travel visas, frequent flyer numbers, airline miles accounts, membership cards, gym subscriptions, and business licenses organized. Quick access to all your memberships and travel documents when you need them.
Your data belongs to you. Export all your files, chats, and forms at any time with one click. Everything downloads fully decrypted and ready to use—no proprietary formats, no vendor 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

No hidden fees. No data mining. Just secure storage.
All plans include the same security features. We don't compromise on encryption based on price.
💡 Share freely: Only the file owner uses their storage quota. People you share with can access files on the free plan—no paid subscription required.
Take complete control. We're working on a self-hosted version that you can run on your own servers. Perfect for organizations with strict data sovereignty requirements or anyone who wants absolute control over their infrastructure.

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. Because we're open source, you could 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 open source—you can audit 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.
