About SiteReset
SiteReset deletes a site’s cookies when you close the last tab for that site.
Trusted sites go on the Keep list and stay signed in. Sites you might come back to in a few minutes go on the Grey list: SiteReset waits (15 minutes by default) and cancels the delete if you reopen a tab.
Everything else is cleaned when you leave.
This is a Manifest V3 Chrome extension. It is a spiritual successor to Cookie AutoDelete — same job, new original source, no telemetry.
HOW IT WORKS
• Sites are grouped by eTLD+1. github.com and gist.github.com are one site. name.github.io is its own site.
• Closing the last tab, or navigating the last tab away, is what triggers cleanup.
• Keep = never auto-delete.
• Grey = delay, then delete, unless a tab comes back.
• Optional chrome.browsingData cleanup can also clear local storage, IndexedDB, Cache Storage, and service workers for that site.
• Import and export your lists as JSON. No account.
FREE FOREVER
Last-tab cookie delete, Keep, Grey, manual clean, and import/export are free. That is the product. Paying is optional.
OPTIONAL PRO ($19 lifetime or $3/month)
Unlocks Chrome Keep-list sync, extra browsingData cleanup presets, and optional export reminders. Paid users still get no telemetry. Checkout is Stripe.
WHAT IT DOES NOT DO
• It does not send your lists, cookies, or history anywhere.
• It does not include analytics, crash reporting, ads, or remote configuration.
• It does not run on Firefox in v1.
Single purpose: remove leftover site data after you leave a site, with explicit exceptions.
