How it works

End-to-end encrypted

Everything is encrypted on your device before upload. The server stores only ciphertext.

Ephemeral by design

Every file has a TTL. When time is up, it is permanently deleted. Nothing lingers.

AI agent ready

Works in automated pipelines and with AI agents. Structured JSON output, non-interactive operation, and clean exit codes.

CLI native

One binary, no account, no config. Install and go.

Zero knowledge

The server never sees your data. Everything is encrypted before it leaves your device.

1.
File contents Encrypted on your device before upload. The server only stores ciphertext.
2.
File names Embedded inside the encrypted payload. Invisible to the server.
3.
Passwords Never transmitted. Used locally to derive the encryption key.
4.
Encryption Argon2id + XChaCha20-Poly1305 authenticated encryption.
