Privacy is a human right. Before anything touches a cloud drive, encrypt it with VaultX — clouds get breached, encrypted data cannot be.

ENCRYPT FIRST. SLEEP HAPPY. YOUR DATA STAYS YOURS.

What is Encryption?

Encryption is the process of converting your readable data into an unreadable scrambled format using a mathematical key. Only someone with the correct key can reverse the process and read your original data.

AES-256

2²⁵⁶ possible keys, more than atoms in the universe

Zero Servers

100% of encryption happens on your device

Post-Quantum

Resistant to attacks from quantum computers

How VaultX Works

Choose your file

Drop any file. It stays on your device.

Set your password

It becomes a key through 600,000 rounds of hashing.

The missing points are browser platform limits shared by every web-based encryption tool — a web page can't fully erase memory, and real-device testing is still ongoing. This is our own audit, not a third-party certification.

Questions

Can VaultX see my files?+

Never. Encryption runs in your browser. Your file and password never leave your device.

Is there a file size limit?+

There's no set limit. Files are processed on your device, so very large files are limited by your device's memory.

What if I forget my password?+

Nobody can recover it, not even us. There is no backdoor.

Is this quantum-safe?+

Yes. Choose the Post-Quantum (ML-KEM-1024) option to protect against future quantum attacks.

Can I use this offline?+

Yes. The published site works with no internet after your first visit.

Is the code open source?+

VaultX is built to be open-source ready. The code uses standard, auditable browser cryptography.
