> How Maro Labs handles data: Maro Portal keeps records on your own Mac, AI calls go only to the providers you connect, work is checked by a separate reviewer, and AI drafts join a manuscript only when the writer adopts them.

# Security & data

Where your data lives in our apps, where AI calls go, and how work is checked before it counts.

## Your data

- **Records stay on your Mac**:

  Maro Portal is a native macOS app with a local Node.js server on the same Mac. Your records stay in the app's data folder on your own Mac.
- **You choose where AI calls go**:

  AI calls go out only to the providers you connect: Anthropic Claude, OpenAI Codex, or an on-device model.
- **History survives a model change**:

  Providers are replaceable parts. When the model changes, a task keeps its history.
- **Your manuscript stays yours**:

  In Maro Writer, AI drafts join the manuscript only when you adopt them, and the original is kept separately.

## How work is checked

- **Separate reviewer**:

  Work is checked by a separate reviewer before it closes.
- **Named receipts**:

  Each review receipt names the provider that did the review. A partial pass is never rounded up to a full one.
- **Decisions are traceable**:

  Decisions are logged with their original wording and where they were said.
