Your Secrets, Zero Knowledge
Store and share sensitive information with military-grade encryption. Even we can't read your data.
Zero-Knowledge
All encryption happens in your browser. Passwords never leave your device. Even if we're hacked, your data stays safe.
AES-256-GCM
Military-grade encryption with authenticated encryption. Wrong password? Instant detection, no garbage data.
Secure Sharing
Share encrypted memos via links. Set expiration dates and view limits. Password shared separately.
Cross-Platform
Access your encrypted memos from any device, anywhere.
Unbreakable by Design
Not even quantum computers can crack your secrets
AES-256 Encryption
Breaking AES-256 would require checking 2²⁵⁶ possible keys. That's more combinations than atoms in the observable universe. Every supercomputer on Earth running for billions of years couldn't crack a single memo.
Quantum-Resistant
While quantum computers threaten RSA encryption, AES-256 remains secure. Grover's algorithm only reduces security to 2¹²⁸ operations—still computationally impossible for any technology foreseeable in the next century.
PBKDF2 Key Derivation
Your password goes through 100,000 rounds of cryptographic hashing before becoming an encryption key. This makes brute-force attacks economically unfeasible, even with specialized hardware.
"The mathematics don't lie. With proper implementation, AES-256 encrypted data will remain secure until the heat death of the universe."— Cryptography Research Community
How It Works
Write your secret memo
Enter your sensitive information - API keys, passwords, private notes.
Set a strong password
Your memo is encrypted in-browser with AES-256-GCM before it ever leaves your device.
Access anytime, anywhere
Only the encrypted data is stored. Enter your password to decrypt and view.
Important: No Password Recovery
We do not store your passwords. If you forget your password, your data is permanently unrecoverable. This is by design for maximum security.
Our Philosophy
True Privacy: A Promise We Keep by Keeping Nothing
SecureVault is not just a memo storage service. This is our declaration of digital-age privacy.
We do not keep any key that can access your secrets. Not server admins, not developers, not government requests—no one in this world can decrypt your encrypted data. There are no backdoors, no master keys. You are the only owner of your unique key.
This promise comes with responsibility. If you forget your password, the secrets inside are gone forever. We cannot recover them. This is not a flaw but an intentional design. True privacy means a safe that only the owner can open, not one that someone "could open if they wanted to."
Keeping a secret sometimes means accepting the possibility of losing it forever. SecureVault exists for those who understand that weight.
What Our Users Say
Real reviews from security-conscious professionals
"I manage infrastructure for a fintech startup, and we have dozens of AWS access keys, database passwords, and API tokens scattered across our team. Before SecureVault, we used a shared spreadsheet (I know, terrible). Now each credential lives in its own encrypted memo. The zero-knowledge architecture means even if SecureVault gets breached, attackers get nothing but gibberish. Finally sleeping well at night."
Marcus Chen
Senior Backend Engineer, San Francisco
"As a freelance management consultant, I handle sensitive client information daily—contract terms, negotiation strategies, competitive intelligence. I needed somewhere to keep notes that even my cloud provider couldn't access. SecureVault's client-side encryption means my notes are encrypted before they ever leave my browser. I've recommended it to every consultant in my network."
Sarah Mitchell
Freelance Consultant, Boston
"Running a Series B startup means handling extremely sensitive data—cap tables, acquisition offers, board meeting notes, investor communications. I was paranoid about storing this anywhere digital. SecureVault changed that. The fact that they mathematically cannot access my data (not just 'promise not to') gives me the confidence to actually use digital tools for sensitive planning."
James Rodriguez
Startup Founder & CEO, Austin
"I've spent 15 years breaking into 'secure' applications. Most encryption implementations have fatal flaws—keys stored server-side, weak key derivation, or encryption at rest but not in transit. SecureVault does it right: PBKDF2 key derivation, AES-256-GCM authenticated encryption, and true client-side processing. I actually trust this with my own secrets, which is rare."
Alex Thompson
Cybersecurity Consultant, Denver
"In investigative journalism, source protection isn't just ethics—it's life and death. I've seen colleagues forced to reveal sources through legal pressure on their service providers. With SecureVault, even a court order to the company produces nothing useful. They don't have my decryption keys. My sources stay protected because the architecture makes betrayal impossible."
Rachel Greene
Investigative Journalist, Washington D.C.
"Attorney-client privilege is sacred in my profession. I handle high-profile criminal defense cases where leaked information could destroy lives. I use SecureVault for case strategy notes, witness information, and evidence analysis. The zero-knowledge model means I can honestly tell clients that nobody—not even a data breach—can compromise their confidential information."
David Park
Criminal Defense Attorney, Chicago
"Our DevOps team manages credentials for 200+ production servers across three cloud providers. Before SecureVault, we had passwords in Slack DMs, sticky notes, and a terrifying shared Google Doc. Now we have organized, encrypted memos with secure sharing. When someone leaves the team, we rotate credentials knowing the old access is cryptographically useless."
Kevin O'Brien
DevOps Lead, Seattle
"I started using SecureVault as a private journal during a difficult time in my life. There are thoughts I needed to process that I couldn't risk anyone ever reading—not hackers, not the company, not even future me if I forgot the password. The guarantee that my entries are truly private lets me be completely honest with myself. Only wish there was a mobile app!"
