SGraph Send

Zero-knowledge encrypted file sharing. Your files, encrypted in your browser, before they ever leave your device.

Encrypted in your browser

Your files are encrypted with AES-256-GCM using the Web Crypto API before they leave your device. The encryption key is generated locally and never sent to the server.

We never have the key

The server stores only encrypted bytes. It has no way to read your files. Even a complete server breach cannot expose your data.

Transparency, not trust

The transparency panel shows you exactly what the server captured and what it did not. No surprises. No hidden tracking. Verify it yourself.
