TabSweep — Auto-Clear Cookies & Storage on Tab Close

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. Not affiliated with Cookie AutoDelete or its authors.
