# Privacy Policy — Tab Vacuum _Last updated: 6 August 2026_ ## Summary Tab Vacuum does not collect, store, transmit, or sell any data. There is no account, no sync, no analytics, and no server — the extension has no way to send information anywhere, because it makes no network requests at all. ## What the extension reads When you click **Scan my tabs**, Tab Vacuum reads the following from the tabs open in your normal browser windows: - the tab's URL and title, to identify duplicate tabs and unused new-tab pages - the tab's window, index, and tab-group id, to group and order the results - whether the tab is pinned, playing audio, or the only tab in its window, so those tabs can be protected from closing - the tab's last-accessed timestamp, shown as context in the results This requires the `tabs` permission, which Chrome describes as *"Read your browsing history"*. That warning string is broader than what this extension does: `tabs` is simply the permission that stops Chrome from redacting `tab.url` and `tab.title`, and reading those is the entire feature. ## What happens to that information It is held in memory for the duration of the scan and used to render the results on screen. It is never written to disk, never placed in browser storage, never logged, and never sent anywhere. The extension declares no `storage` permission, so it cannot persist anything between runs. It has no background service worker and keeps no state — the review page re-runs the scan when it loads rather than receiving a saved copy. Closing the popup or the review page discards everything. ## Network access None. Tab Vacuum makes no HTTP requests, loads no remote scripts or fonts, contacts no analytics or crash-reporting service, and includes no tracking of any kind. All code is contained in the extension package. ## Page content Tab Vacuum declares no host permissions and injects no content scripts, so it cannot read, modify, or interact with the contents of any web page you visit. It sees a tab's address and title, never what is inside it. ## The one way information leaves the extension The **⧉ Copy report** button copies a plain-text report of the scan — including tab URLs and titles — to your system clipboard. This happens only when you click that button, the data goes only to your own clipboard, and nothing is transmitted. Paste it wherever you choose, or don't use the button at all. ## Optional permission `tabGroups` is optional and is never requested unless you click **Show group names**. It is used only to display a tab group's name and colour in the results instead of a generic number. Declining it costs nothing but those labels. ## Permissions in full - `tabs` — required. Reads tab URLs and titles so duplicates and unused new tabs can be identified. - `tabGroups` — optional. Displays tab-group names and colours. No host permissions. No content scripts. No `storage`. No remote code. ## Children Tab Vacuum is not directed at children and collects no data from anyone, including children. ## Changes to this policy Any change will be published in this file in the extension's public repository, with the date above updated. ## Contact Questions about this policy: open an issue at .
