Zero-Knowledge Encryption
Your files are encrypted in your browser using AES-256-GCM before upload. The server stores only encrypted ciphertext. Your decryption key never leaves your device.
Browser Encryption
AES-256-GCM encryption runs entirely in your browser via the Web Crypto API. Files are encrypted before they ever leave your device.
Zero Knowledge
The server never sees your plaintext data, your file names, or your encryption keys. Even if someone accessed our servers, they would only find meaningless encrypted data.
Open Source
The entire codebase is public on GitHub. Inspect the encryption yourself. Deploy on your own infrastructure. Free forever.
