browser-zero privacy policy

Effective date: 2026-05-11

browser-zero is a Chrome extension that shows every open tab across every Chrome window on one page, so you can search, group, drag between windows, and bulk-close tabs.

What data the extension reads

To show you your tabs, browser-zero reads the following from Chrome via the chrome.tabs and chrome.tabGroups APIs:

• The list of open tabs in each Chrome window
• Each tab’s title, URL, favicon URL, and last-accessed time
• Each tab’s window and Chrome tab group (if any), including the group’s title and color

When you act on tabs from the dashboard, browser-zero also asks Chrome to:

• Focus a tab and its window (when you click a row)
• Close one or more tabs (when you click × / Close? / bulk Close?)
• Move a tab between windows (when you drag a row to another window section)
• Create a new Chrome tab group or add tabs to an existing group (when you use the “Add to group” action)

Where that data goes

Nowhere. browser-zero does not transmit any of this data to any server. There is no telemetry, no analytics, no error reporting, no cloud sync, and no third-party SDKs. Everything happens locally in the extension page running on your machine.

What is stored

Nothing persistent. The dashboard is stateless — every time you open it, it asks Chrome for the current set of tabs. Closing the dashboard tab forgets everything. No chrome.storage, localStorage, IndexedDB, or cookies are used by the extension.

Network requests

The only network requests the extension makes are the favicon <img> tags loading favicons from each tab’s origin server (the same servers your browser already contacted to load those tabs). browser-zero does not send your data to those servers — it only requests the favicon image, which the browser would have requested anyway when loading the tab.

Permissions and why each is needed

• tabs — to read the list of open tabs and their titles, URLs, and favicon URLs; to focus, close, and move tabs at your request.
• tabGroups — to read which Chrome tab group each tab belongs to and to create / modify groups when you use the “Add to group” action.

The extension does not request host permissions for any specific website.
