Custodian: Auto-Clear Cookies, Cache & Permissions

Custodian automatically cleans up a website the moment you're finished with it. When you close the **last tab** for a site, Custodian waits through a short, cancellable grace period, then removes the site's cookies, storage, cache, and resets any permissions it was granted. No manual cleaning. No scheduled jobs. No remembering to clear browsing data. ### What Custodian clears * Cookies * localStorage & sessionStorage * IndexedDB * Cache Storage * Service Workers * WebSQL (where supported) * Site permissions, including camera, microphone, location, notifications, clipboard, automatic downloads, sound, and pop-ups Custodian only cleans a site after its **last open tab** has been closed, so it never interrupts websites you're actively using. ### Whitelist & Greylist Keep selected sites untouched by adding them to your whitelist or greylist. Perfect for email, banking, work accounts, or anywhere you want to stay signed in. Prefer the opposite behavior? Enable **Shield Mode** to clean only the sites you explicitly choose instead of cleaning everything by default. ### Isolate This Tab Need a page to stay open without making normal network requests? **Isolate This Tab** lets you temporarily block a tab's standard network traffic while leaving the page itself open. ### Activity Log & Receipts Every cleanup generates a detailed receipt showing exactly what was removed and which permissions were reset. Review recent activity from the popup or browse the full history whenever you need it. Custodian can also suggest frequently visited sites for your whitelist using simple local pattern matching. Suggestions are never applied automatically—you stay in control. ### Privacy by Design Custodian works entirely on your device. * No accounts * No sign-in * No analytics * No telemetry * No remote configuration * No network requests Everything stays in your browser. Nothing is sent anywhere.
