Two questions decide the privacy of any prompt: what is kept, and who can see it. This page answers both for the plugin.

What Nito Keeps

Nito does not store the contents of your calls. Your prompts, the responses, reasoning, tool payloads, and attachment contents are used to serve the request and are never persisted. Conversation history, where it exists, lives on your machine. What Nito keeps is operational metadata, the minimum needed to run and bill the service. This holds at every level. Private adds the upstream provider being held to zero data retention on top of it.

Who Can See What

Retention is separate from visibility. Even when Nito keeps nothing, the question of who sees a prompt in the first place depends on which command you used. The takeaway: keeping your prompt away from your harness is about which command you choose, while keeping it from the provider is about the model’s level. See What Each Command Protects for the command side, and The Four Levels for the level side.

Confirming It Yourself

For the strongest levels, you do not have to take retention behavior on trust: a Confidential call produces a signed attestation you can verify. See TEE Attestation.
