Zero-Knowledge Architecture
Your files are encrypted before they leave your device. Our servers process encrypted data only. We have no technical ability to read your documents — not because of policy, but because of architecture.
The world's most private cloud storage
Your will. Your children's passports. Your home purchase contract. The photos that can never be replaced. These deserve more than a corporate server in California — they deserve CloudLock.
Trusted by families, lawyers and business owners across Europe
Until the day you need them.
A flooded hard drive. A hacked Google account. A phone that doesn't turn on. A cloud provider that changes its terms overnight.
CloudLock exists for that day. So it never comes.
You upload a document. Everything else happens automatically, silently, and without anyone — including us — being able to read it.
Even if Google, MEGA and OneDrive were all hacked simultaneously — your documents would remain completely unreadable.
“We use Zero-Knowledge Architecture with military-grade AES-256 encryption. Your data is encrypted in transit on our isolated server before it touches any cloud storage. Not even Google Drive's technical staff can see the name or contents of your files. That is not a feature. That is a promise.”
— Founder & CEO, CloudLock
We're not saying Google Drive is bad. We're saying some documents deserve better.
What happens to your family's most important documents when you're gone? Where is your will? Who knows the PIN to your accounts? Where are the children's birth certificates? CloudLock is the answer to questions your family hopes they never have to ask.
Create a family vault. Add your partner. Add your children when they're ready. Leave documents, letters, instructions — knowing they'll be there exactly when they're needed.
"I set up CloudLock after my father passed and we spent three weeks looking for his documents. I never want my children to go through that." — Early CloudLock user
Lawyers. Notaries. Accountants. Doctors. Financial advisors.
You handle documents that define people's lives — their assets, their health, their legal standing. A single data breach doesn't just damage your reputation. It destroys trust that took years to build.
CloudLock gives you infrastructure that matches the weight of that responsibility. Every document isolated, encrypted, distributed. Every access logged. Every share time-limited and password-protected.
GDPR compliant. Audit-ready. Built for professionals who can't afford mistakes.
CloudLock uses a combination of technologies that, together, create a level of security that no single cloud provider can match.
Your files are encrypted before they leave your device. Our servers process encrypted data only. We have no technical ability to read your documents — not because of policy, but because of architecture.
The same standard used by governments and military organizations worldwide. Currently considered unbreakable with any known computational method.
Your encrypted file is split into fragments using a chunking algorithm. Each fragment is stored on a different cloud provider. A complete file requires all fragments — making any single-provider breach completely useless to an attacker.
The same open-source technology trusted by thousands of enterprises worldwide handles the distribution, synchronization and retrieval of your fragments across providers.
Google Drive, MEGA, OneDrive, Dropbox — if any one of them goes down, your files are still fully accessible through the others. We've engineered redundancy into the foundation.
We don't charge per gigabyte. We don't have hidden fees. One plan for families, one for businesses.
All plans include AES-256 encryption, distributed storage across 3+ cloud providers, and zero-knowledge architecture. No plan includes us reading your files — because we architecturally cannot.
