Wipeout Auto

Automatically clears cookies, localStorage, IndexedDB, cache storage, service workers, and history when you leave a site — with a configurable whitelist to stay logged in.

Built in the spirit of Cookie AutoDelete, which is no longer maintained for Chromium MV3. Wipeout Auto is MV3-native and adds per-category controls, a browser-restart full sweep, and JSON whitelist import/export.

What it does

- Per-site cleanup on leave. When the last tab on a domain is closed (or the only tab navigates away), Wipeout Auto clears that site's cookies, local storage, IndexedDB, cache storage, service workers, and history entries — after a configurable delay (default 5 seconds).
- Whitelist to stay logged in. Whitelisted domains keep their cookies / localStorage / IndexedDB so you don't lose login state. Cache, service workers, and history are still cleared.
- Wildcard whitelist entries. Add *.example.com to whitelist every subdomain. The leading dot is required so evilexample.com doesn't accidentally match. example.com and *.example.com are independent — whitelist each separately if you want both.
- Full sweep on browser startup. Optionally, clears all non-whitelisted domains plus a global pass for cache, downloads, form data, and history.
- Activity log. Every cleanup is logged with the trigger, domain, whitelist status, categories cleared, and cookie count. Capped at 2000 entries; entries older than 30 days auto-purge.

Using it

Popup (toolbar icon)
- Shows the current site, the live cookie count, and up to three whitelist candidates (parent-wildcard, self-wildcard, apex). Click Whitelist / Remove to toggle each.
- Clean Now clears the current site immediately. If the site is whitelisted, you'll get a confirmation prompt — proceeding overrides the whitelist for that single cleanup.
"Last cleaned for " line shows the most recent cleanup timestamp.
- Open Settings opens the full settings page.

Settings page
- Whitelist: add, remove, or review whitelisted domains. Apex (example.com) and wildcard (*.example.com) are stored as separate entries.

Advanced settings:
- Auto-cleanup delay (0–30 seconds). The grace period between a tab closing and cleanup firing. Reopening the site within this window cancels the cleanup.
- Categories to clear, separately for non-whitelisted vs whitelisted domains. Defaults: non-whitelisted clears everything; whitelisted preserves cookies / localStorage / IndexedDB.
- Browser startup full sweep toggle. The categories cleared at startup are not individually configurable — only the toggle.
- Reset to defaults button restores the original advanced settings.
- Activity log with relative timestamps (hover for absolute), trigger, domain, whitelist status, categories cleared, and cookie count. Filter by domain.
