End-to-End Encryption
AES-256 GCM encryption ensures that only you and your recipient can read the contents. No exceptions.
verified_user
Encrypted Before Upload
The server receives only ciphertext. Passphrases and decryption keys never leave the sender’s or recipient’s browser.
timer_off
Auto Expiry
Links automatically self-destruct after a set period, from 1 hour to 30 days.
delete_sweep
Burn on Read
Enable "Delete After First Access" to ensure the document vanishes the moment it is viewed.

Instant PDF Viewer
A seamless, secure browser viewer. No downloads required if you choose not to.

"We couldn't read your files even if we wanted to."
Local-First Architecture
Unlike traditional cloud storage, the encryption happens on your CPU. We only see encrypted ciphertext. Your passphrase never reaches our database.
industry-standard Standards
We utilize industry-standard Web Crypto APIs and AES-256 encryption. This is the same protocol used for widely deployed encrypted messaging and TLS.
Server never sees file contents
HOW IT WORKS ?
Your file
Encrypted in browser
Server
(Encrypted only)
Recipient decrypts
We can't see your files. Ever.
Everything happens locally in your browser; our servers only see encrypted data that even we don't have the keys to unlock.

How it works: Web Crypto API
We leverage the native browser Web Crypto API to perform cryptographic operations. This ensures that encryption happens at near-native speeds directly in your user agent, never touching a remote server in plaintext.
Client-Side Scoping
Your browser's memory is a sandbox. Encryption happens within this isolated environment.
Native Performance
Hardware-accelerated encryption ensures your machine stays cool while files stay safe.

Only randomized ciphertext blocks. No metadata, no previews, no filenames.
vpn_key
Where the key is
The private key is generated locally on your machine. It is never transmitted. To share a file, the key is passed via a secure URL fragment that browsers never send to servers (anything after the #).

Key Sovereignty
You own the locks.
If you lose your recovery key, even we cannot reset your access. Your security is absolute because your control is absolute.
