Your personal cloud encrypted end-to-end

Store your files with full confidentiality. Not even we can read your data. Client-side libsodium encryption — unlocked only with your password, on any device.

Secure cloud storage that genuinely protects your files

May·Secret encrypts your files in your browser before upload. Their contents, names and folder structure remain unreadable to the server.

End-to-end encryption

Your files are encrypted before they're sent. We only ever see encrypted data.

Hosted in France

Data stored at o2switch in Clermont-Ferrand. Full GDPR compliance.

Intuitive organization

Folders, search and previews — all while staying encrypted.

How does your encrypted cloud work?

Privacy is built into every step without making your documents harder to access.

1. Encryption on your device

Your browser encrypts every file with libsodium. The private key needed to read it is never sent in clear text.

2. Storage in France

Only encrypted data is uploaded and stored by our French hosting provider in Clermont-Ferrand.

3. Access with your password

On your devices, your password unlocks your key and files locally. May·Secret cannot do this on your behalf.

From personal memories to confidential business documents

Keep the files you do not want to entrust in readable form to a conventional cloud provider in one place.

For your personal files

Keep photos, archives and administrative documents in a private, organized space available from your devices.

For your professional work

Protect contracts, client records and sensitive work documents. Team plans let authorized members share encrypted files.

Verifiable security, not just a promise

We explain the algorithms we use, what our servers can see and the consequences of end-to-end encryption. Explore our security architecture and the commitments behind the service.
