# OpenGuanlan Browser Bridge Privacy Policy

Effective date: 2026-05-13

OpenGuanlan Browser Bridge is a read-only browser extension for Guanlan. It helps AI agents collect user-authorized target-page visible evidence from Chrome or Chromium and send it to a local `openguanlan daemon` running on the same computer.

## Data Collected

The extension can read the current target page URL, title, visible text, visible links, visible frame metadata, and visible HTML structure after the user grants the current site and authorizes a Guanlan browser-assist task.

The extension does not collect or read cookies, tokens, passwords, localStorage, sessionStorage, browser profiles, browser databases, keychain data, hidden credential fields, or unrelated private pages.

## Data Use

Data is used only to create Guanlan browser-visible evidence for the target page requested by the user. The extension sends results only to the local `openguanlan daemon` on `127.0.0.1` or `localhost`. The extension does not sell data, use data for advertising, or send browser page content to a remote server.

## Permissions

The extension uses `tabs`, `scripting`, `activeTab`, localhost host permissions, and optional per-site host permissions. It does not request cookie, storage, debugger, downloads, or native messaging permissions.

## User Control

Users choose which sites to grant. Users can revoke site permissions in Chrome's extension settings at any time. Users can stop the local bridge by terminating the `openguanlan daemon` process.
