Privacy Policy — Close All Duplicate Tabs

Last updated: February 11, 2026

Overview

Close All Duplicate Tabs is a Microsoft Edge browser extension that closes duplicate browser tabs. This privacy policy explains what data the extension accesses and how it is handled.

Data the Extension Accesses

When you activate the extension (by clicking its toolbar icon or pressing its keyboard shortcut), it reads the URLs of your currently open tabs in order to identify duplicates. This is the sole data the extension accesses.

Data Storage

The extension stores your settings (such as URL matching preferences and scope) locally on your device using the browser’s built-in storage API (chrome.storage.local). These settings never leave your device.

Data Collection

This extension does not collect, transmit, or share any data. Specifically:

• No browsing history is collected or stored
• No tab URLs are recorded, logged, or transmitted
• No personal information is collected
• No analytics or telemetry of any kind is used
• No cookies are set
• No network requests are made
• No data is sent to any server, third party, or external service

Permissions

The extension requests two browser permissions:

• Tabs: Required to read the URLs of open tabs so that duplicates can be identified and closed. No page content is accessed or read.
• Storage: Required to save your settings locally on your device.

Third Parties

This extension has no third-party dependencies, integrations, or services. It operates entirely within your browser on your device.

Changes to This Policy

If this privacy policy is updated, the changes will be reflected in the “Last updated” date above.
