What Hemingweight Does

Hemingweight is a browser extension that provides a coding environment in your browser. It connects to a local server running on your own computer to manage files, run commands, and interact with an AI coding assistant.

Data Collection

The Hemingweight extension does not collect, store, or transmit any personal data. Specifically:

• No analytics or tracking of any kind
• No cookies or fingerprinting
• No data is sent to Hemingweight servers (there are none)
• No browsing history, passwords, or form data is accessed

How the Extension Works

The extension communicates exclusively with a local server running on your machine at localhost:3456. It uses two Chrome permissions:

• sidePanel — to display the coding environment as a browser side panel
• nativeMessaging — to automatically start the local server if it is not already running

All communication stays on your computer. No data leaves your machine through the extension.

AI Coding Assistant

The local server connects to an AI coding assistant (such as Claude Code by Anthropic) that you install and authenticate separately. When you use the AI assistant, your prompts and code are sent to the AI provider according to their terms and privacy policy. Hemingweight does not control or intermediate this communication — it is handled entirely by the CLI tool you choose to use.

Local Storage

The local server stores configuration (such as your projects directory preference) in ~/.hemingweight/config.json on your computer. This data never leaves your machine.

Open Source

Hemingweight is fully open source. You can inspect the complete source code at github.com/AlexandreFlamant/Hemingweight.
