Privacy — Radiant Browser Bridge

Last updated 3 September 2026 · Templeton Technologies

The extension talks to one address: 127.0.0.1 on your own Mac. It has no server of its own, sends nothing to Templeton, and makes no request to anything on the internet. It is a cable between the browser you are already using and the Radiant app running on the same machine.

What it does

Radiant is a coding app that runs locally on your Mac. When you ask its agent about a web page, this extension is how it looks: it can list your open tabs, read the text of a page, capture a screenshot of it, click an element, and fill in a field — each time, because Radiant asked, and Radiant asks because you did.

What it collects

Nothing. The extension stores no page content, no browsing history, no credentials and no identifiers. It keeps no database and writes nothing to disk. Page text and screenshots pass through the local connection to Radiant on your machine and are not retained by the extension.

Why it asks for access to all sites

The agent works on whatever page you point it at, and that could be any site, so the permission cannot be narrowed in advance. Nothing is read unless Radiant — running on your Mac, at your request — asks for it.

Where anything you look at can end up

The extension itself sends nothing anywhere. But Radiant is an AI coding app, so if you ask an agent about a page, the text or screenshot Radiant collected is included in the message sent to whichever model you have chosen. If that is a cloud model — Anthropic, OpenAI, xAI and so on — that content goes to that provider under their terms, exactly as anything else you type does. If it is a local model, it never leaves the machine. You choose the model, and you choose which page to ask about.

Turning it off

Quit Chrome, quit Radiant, or remove the extension. Any of the three unplugs it completely; there is no account to close and nothing to revoke.
