No data collection

Privacy Policy — Close Duplicate Tabs & Group by Type – DedupNewFun

Last updated: August 4, 2026

DedupNewFun (“the extension”) is a Chrome extension that helps you clean up and organize
your open browser tabs. This policy explains, plainly, what the extension does and does
not do with your data.

Summary

• The extension does not collect, store, transmit, or sell any personal data.
• The extension does not contain analytics, telemetry, or crash-reporting SDKs.
• The extension makes no network requests of its own — the only pages it ever
  opens are ones already open in your own tabs, or ones you explicitly asked it to open.
• All settings are stored locally (via Chrome’s own sync storage) and never leave your account.

What data is processed, and where it stays

To do its job, the extension reads basic metadata about your open tabs — URL, title, favicon,
pinned/active state — using Chrome’s own tabs API. This is read in memory, used
immediately to perform the action you requested (closing a duplicate, grouping tabs, showing
the preview list), and is never saved, logged, or sent anywhere.

If you turn on the advanced preview page’s optional “Capture preview” feature, a screenshot of
the one tab you click is captured on demand and held only in that page’s memory for as long as
it stays open — it is never uploaded, saved to disk by the extension, or sent anywhere.

Your own preferences (scope, sort order, custom grouping rules, whether double-click-to-duplicate
is enabled) are saved using chrome.storage.sync — the browser’s own built-in sync
between your own devices, handled by Google/Microsoft. This data is local to your account, never
accessible to the developer, and never shared with any third party.

Permissions and why they are needed

• tabs — to list, close, update, and duplicate tabs in response to your actions.
• tabGroups — to create and name native Chrome tab groups when you group by service.
• storage — to save your own preferences locally, synced only to your own devices.
• contextMenus — to add the extension’s actions to the icon’s right-click menu.
• scripting — to run a small local “safe to close” check before closing a tab, and
  to support the optional on-demand screenshot feature.
• host_permissions (<all_urls>), optional — requested only if and when you
  turn on thumbnail capture, since a thumbnail can be of any site you have open.

None of these permissions are used to collect, read, or transmit the content of the pages you visit.

Third parties

The extension does not integrate any third-party service, advertising network, or data broker.
There are no external scripts, no remote code execution, and no calls to any server —
everything runs locally in your browser.

Children’s privacy

The extension does not knowingly collect any data from anyone, including children, because it does not collect data at all.

Changes to this policy

If this policy ever changes — for example, if a future version adds an optional feature that
involves data handling — this page will be updated first, and the change will be clearly
disclosed before it takes effect.
