Privacy Policy
Last updated: August 7, 2026
MRU Tab Switcher ("the extension") is designed to do one thing: let you switch between your recently-used browser tabs. This policy explains what data the extension touches and — just as importantly — what it never does with it.
Summary
- No data ever leaves your browser.
- No servers, analytics, trackers, or third parties are involved.
- No account, sign-in, or personal information is required or collected.
- Nothing is sold, shared, or used for advertising.
What the extension accesses
To build the list of recent tabs and let you search open tabs, the extension reads, locally on your device only:
- Tab titles, URLs, and favicons of your currently open tabs.
- Which tab is active, and the order tabs were used/opened in, per browser window.
This information is used solely to render the switcher overlay (the list of tabs and search box shown on Ctrl+`) and to activate the tab you choose.
What the extension stores
The recent-tab order is kept in memory and mirrored to
chrome.storage.session, a temporary, local storage area
provided by Chrome that is automatically cleared when your browser
session ends. This is only so the tab order survives the extension's
background service worker being briefly unloaded and reloaded by
Chrome — it is never synced, uploaded, or made available outside your
own device.
What the extension does NOT do
- It does not read or store the content of web pages you visit.
- It does not transmit any data over the network — the extension makes no network requests at all.
- It does not use cookies, analytics, or third-party SDKs.
- It does not track your browsing history beyond the in-memory recent-tab order described above.
Permissions
The extension requests the minimum permissions needed for this functionality — see the project's permissions justification for a detailed explanation of each one.
Changes to this policy
