Privacy Policy

The short version

ATO does not collect, transmit, sell, or share any of your data. Everything the extension does happens locally, inside your own browser. It makes no network requests, contains no analytics or trackers, and has no backend server.

What ATO accesses (and why)

To do its job, ATO reads information about your open tabs entirely on your device:

• Tab titles and URLs — used to detect duplicate tabs, power search, and group tabs by domain. This information is read in memory to render the popup and is never sent anywhere.
• Favicons — each tab's icon is displayed in the popup using the icon URL the browser already has for that tab.
• Recently closed tabs — used only to provide the "Undo" feature, via Chrome's sessions API.

Settings storage

Your preferences (theme, font, duplicate-matching mode, badge options, tab protection) are saved using Chrome's storage.sync API. If you have Chrome Sync enabled, these settings sync across your own signed-in browsers through your Google account. ATO itself never receives this data — it is handled by Chrome.

Data sharing

ATO does not sell or transfer any user data to third parties. It does not use or transfer data for any purpose unrelated to its single purpose, and it does not use data to determine creditworthiness or for lending purposes.

Permissions

• tabs — read tab titles/URLs to detect duplicates, search, and group tabs.
• storage — save your settings locally / via Chrome Sync.
• sessions — restore recently closed tabs (Undo).
• Host access (<all_urls>) — read tab URLs to detect duplicates and load favicons. URLs are only processed locally.
