Privacy Policy

Localhost Port Dashboard — Last updated: April 9, 2026

Overview

Localhost Port Dashboard is a browser extension that monitors locally running development servers on your machine. Your privacy is fundamental to how this extension is built.

Data Collection

We collect no data. Specifically:

• No personal information is collected
• No browsing history is accessed or stored
• No analytics or tracking scripts are included
• No telemetry of any kind is sent
• No cookies are used

Network Communication

The extension communicates only with a companion server running on your local machine at 127.0.0.1:9384. This is the loopback address — traffic never leaves your computer.

The extension makes no requests to any external server, API, or third-party service.

Permissions

The extension requests a single permission:

• host_permissions for http://127.0.0.1:9384/* — Required to communicate with the local companion server. This permission is scoped exclusively to your localhost.

Data Storage

The extension stores no data in Chrome storage, local storage, or any other persistent storage mechanism. All information is fetched live from the companion server each time the popup is opened.

Third-Party Services

This extension uses no third-party services, libraries, or SDKs.

Source Code

The extension and companion server are open source and fully auditable. The companion server uses zero npm dependencies — only Node.js built-in modules.

If this policy is updated, the changes will be reflected on this page with an updated date.
