MailZyro Drive
Private files, plain and simple.
MailZyro Drive encrypts files and file names on your device before upload. The server stores ciphertext, not readable documents.
Why Drive
Storage the server cannot read.
Private by design
Files — and even file names — are encrypted before they leave your device.
Built for normal sharing
Share a link with optional password and expiry; recipients need no account.
Made for daily work
Search, versions, sharing and a macOS app with encrypted local storage.
How encryption works
Your device does the private work.
Drive encrypts your data locally, then uploads only encrypted bytes.
Encrypt on device
Files are encrypted with AES-256-GCM before upload.
Layer the keys
Your OpenPGP key protects a root folder key, which protects folder keys and file keys.
Store ciphertext
The server stores encrypted file contents, encrypted names and encrypted search data.
Share by wrapping keys
Each recipient gets their own OpenPGP-wrapped copy of the file key.
For the technically curious: AES-256-GCM with OpenPGP key wrapping, encrypted names, encrypted search and 64 MB chunked encryption.
What is included
Private storage with useful basics.
Encrypted file names
Drive protects what a file is called, not just what is inside.
Encrypted search
The search index is encrypted; results decrypt only on your device.
Secure share links
Optional password and expiry; recipients need no account.
Version history
Earlier versions of each file are kept.
macOS desktop app
Encrypted local storage (SQLCipher), keys in the Secure Enclave.
Mobile & Windows apps
iOS, Android and Windows are planned — macOS only today.

FAQ
Questions about Drive
You get 5 GB of storage today. Larger storage tiers are planned, but there are no larger quotas available yet.
No. Files are encrypted on your device before upload, and file names are encrypted too, so the server stores ciphertext only.
Yes. Create a share link for someone without a MailZyro account, add an optional password and expiry, and the file decrypts in the recipient’s browser.
Not today. There is a macOS desktop app now; iOS, Android and Windows apps are planned.
Version history is available today, so you can see earlier versions of a file. One-click restore is coming soon — until then, restore is not a shipped feature.
The macOS app stores files encrypted locally. Full offline sync for the web app is limited and should be treated as beta-level, not guaranteed.
Any file type. Drive encrypts files before upload and does not inspect their contents, so documents, images, archives and more are handled as encrypted data.
Keep your files yours.
Use Drive for private storage, sharing and suite files, with 5 GB available today. Your device encrypts the work before MailZyro stores it.
