TabSweep — Auto-Clear Cookies & Storage on Tab Close

About

Clear a website's cookies and site data automatically — the moment you close its
last tab. Delete cookies, reset a website, and log out of a site cleanly, with
zero effort. TabSweep keeps your browser clean and your sessions private.

It's the free, privacy-first replacement for the auto-cookie-cleanup workflow
that Chrome's Manifest V2 sunset took away. No paywall. No whitelist cap. No
accounts. Nothing leaves your computer.

WHAT IT DOES
• Close the last tab of a site → after a short grace period, TabSweep clears
  that site's cookies, localStorage, IndexedDB, and cache.
• "Clean now" — wipe any site's data instantly from the popup, on demand
  (with a quick confirm, since deletion is permanent).
• Keyboard shortcut (Alt+Shift+C, customizable) to clean the current site
  without opening the popup.
• The grace period (adjustable, or instant) prevents data loss during quick
  navigations and accidental tab closes.
• Allowlist any site to keep it logged in — unlimited sites, always free.
  Import and export your allowlist to back it up or move it.
• Master on/off switch, and an optional "cookies only" mode if you'd rather
  leave local storage alone.
• Works in incognito (as a separate, split instance) and across profiles.
• Local-only counters show how many cleanups it has run, per site. That stays
  on your machine.

PRIVACY FIRST — BY DESIGN
• No analytics. No telemetry. No network requests of any kind.
• Works fully offline. All settings and your allowlist live in your browser's
  local storage.
• Open source (MIT). You can read exactly what it does.

WHY THE PERMISSIONS — MINIMAL BY DESIGN
TabSweep asks only for what cleanup genuinely requires, and it does NOT request
broad "read and change all your data on all websites" access at install:
• Read your tabs — to know when a site's last tab has closed.
• Cookies + browsing data — to remove a site's cookies and storage.
• Storage cleanup (localStorage, IndexedDB, cache) works for every site with no
  per-site permission.
• Cookie cleanup is the only thing Chrome host-gates, so TabSweep asks for access
  to a specific site only when you choose to enable cookie cleanup for it — one
  click, in the popup, for that one site. You can revoke it any time.
• TabSweep does NOT inject scripts into pages and never reads page content.
