Shadow DOM Debugger - Privacy Policy

Last updated: March 28, 2026

Overview

Shadow DOM Debugger is a Chrome extension that helps developers find, highlight, and inspect Shadow DOM elements on any web page. Your privacy is important, and this extension is designed to keep all data local to your browser.

Data Collection

Shadow DOM Debugger does not collect, store, transmit, or share any data externally. Specifically:

• No personal information is collected.
• No browsing history is recorded.
• No page content or Shadow DOM data leaves your browser.
• No analytics or tracking scripts are used.
• No cookies are set by the extension.
• No data is sent to external servers.

How It Works

Shadow DOM Debugger uses a content script to scan the DOM tree of web pages and detect elements with attached shadow roots. All scanning, highlighting, and tree rendering happens entirely within your browser. User preferences (such as highlight toggle state) are stored locally using chrome.storage.local on your device. No data is persisted beyond basic toggle preferences.

Permissions

The extension requests the following permissions:

• storage — Used for storing user preferences (such as highlight on/off state) locally on your device.
• activeTab — Required for the popup to identify the currently active tab and communicate with the content script.

Third-Party Services

Shadow DOM Debugger does not use any third-party services, APIs, or SDKs.

Changes to This Policy

If this privacy policy is updated, the changes will be posted here with a revised date. The extension will continue to operate on the principle of zero external data collection.
