Close Tabs privacy policy
Effective date: September 4, 2026
Close Tabs finds and closes browser tabs with matching URLs and titles. This policy explains what data it reads, where that data stays, and what the developer receives.
Tab data
Close Tabs reads the URL, title, loading state, audible state, window, and tab-group placement of each open tab. It uses this information to find matches, show the review list, close the tabs you select, and restore the last closed batch.
When Automatic cleanup is on in Settings, Close Tabs may close matching duplicates after a new duplicate tab finishes loading. Automatic cleanup is off by default.
When the badge is on, Close Tabs counts matching duplicates among open tabs to show a number on the toolbar icon.
Close Tabs does not read page content. Tabs with the same URL but different titles stay open. You can exclude sites where the same URL and title may hold different work.
Close Tabs also reads the site rules you add in Settings. These rules tell it which domains to exclude or how to compare their URLs.
Data use
Close Tabs processes tab data on your device for its duplicate-tab feature. It does not create accounts, run analytics, show ads, build profiles, or use your tab data for another purpose.
Close Tabs' use of information received from Chrome APIs complies with the Chrome Web Store User Data Policy, including its Limited Use requirements.
Storage
Chrome sync storage holds your settings. Chrome may synchronize them when you enable browser sync. Chrome session storage holds the last closed batch so Undo can restore it. A new cleanup replaces the previous Undo batch. Using Undo removes that batch.
The Undo batch stays until the next cleanup, until you use Undo, or until the Chrome session ends. Settings stay in Chrome sync storage until you change them, remove Close Tabs, or clear sync data.
In Chrome Incognito, Close Tabs runs as a separate instance with its own settings and Undo batch.
The developer does not operate an application or backend server for Close Tabs and does not collect user data. A static public site can host this policy. The extension does not send tab data, settings, or other user information to that site.
Sharing and sale
Close Tabs does not sell, share, or send tab data or settings to the developer, advertisers, data brokers, or other companies.
Security
Close Tabs ships all executable code in the extension package. It does not load remote code, make network requests, or send user data to the developer or other companies. Chrome may synchronize settings as described above when you enable browser sync.
Your controls
You can change or restore settings from the extension's Settings page. You can turn one-click mode off in the popup after any toolbar click. Removing Close Tabs from Chrome removes its extension data under Chrome's uninstall rules. You control synchronized data through your Chrome account and sync settings.
Policy changes
The developer will update the effective date and publish the revised policy at the same URL when this policy changes.
