Scan and clean tracking data stored in your browser by websites. 100% local — no data is sent anywhere.
Scan your browser for tracking data: cookies, local storage, session storage, IndexedDB, and cache storage.
This tool only cleans data for the current site domain due to browser security restrictions. To clean data from all sites, use your browser's built-in privacy settings (Ctrl+Shift+Delete).
Every website you visit is allowed to leave behind data in the browser's storage silos: cookies (small key/value crumbs sent with every request, ideal for cross-site tracking), LocalStorage (persistent per-site data that survives restarts), SessionStorage (data that dies with the tab), IndexedDB (structured app databases), and Cache Storage (downloaded assets for offline use). This tool scans all five categories, shows you what each holds, then lets you delete the ones you pick. Cleaning is a browser API call — document.cookie expiry, localStorage.clear(), sessionStorage.clear(), indexedDB.deleteDatabase(), caches.delete() — so everything happens locally and instantly, with zero bytes leaving your device.
Each row is one storage API the browser exposes to sites. The scan counts entries and estimates size; cleaning invokes the matching clear/delete API. Due to same-origin policy the tool can only see and clear data for the site you are currently on.
Dana, a QA engineer, has spent a week testing a login flow on a staging app. The site has left dozens of session cookies, an IndexedDB store with test accounts, and cached assets. She wants a clean slate so the next tester isn't confused by her leftover state.
Scan and clear cookies, cache and localStorage in one click. 100% local, free.
The Browser Privacy Cleaner is a scanner that shows exactly what websites have stored on your machine and lets you delete it selectively. It inspects five storage types that sites use to track you: cookies, localStorage, sessionStorage, IndexedDB databases, and Cache Storage. After a one-click scan, each category appears with an item count and an estimated size in kilobytes, with cookies estimated at roughly 0.3 KB each and storage entries measured by character length. Everything runs locally in your browser through the standard Web Storage and IndexedDB APIs; no data is uploaded, logged, or sent to any server. The tool then clears only the categories you select, leaves the rest untouched, and re-scans to confirm every count dropped to zero.
Anyone who wants to see the invisible footprint websites leave behind. Web developers use it to inspect what their own site writes to localStorage, sessionStorage, IndexedDB, or service-worker caches while debugging. Privacy-conscious users run it before or after visiting sites that rely heavily on tracking cookies. People testing a logout flow can instantly confirm whether session data was really cleared. It is also useful when a site misbehaves because of stale cached data; clearing Cache Storage or cookies for that domain often fixes it. Because the scan and cleanup are per-domain and never leave the browser, it is safe to run on a work machine or shared computer. If you need to wipe data for every site at once, your browser's built-in settings are the right tool.
(1) Click "Scan My Browser Storage" and the tool enumerates every cookie, localStorage key, sessionStorage key, IndexedDB database, and Cache Storage entry for the current domain, then totals the counts and estimated sizes across the five categories. (2) Review the results list, toggle individual categories on or off, or use Select All and Deselect to choose exactly what to remove; categories with zero items are greyed out. (3) Press "Clean" and the tool expires each cookie by setting its expiry to a 1970 timestamp, calls clear() on local and session storage, deletes every IndexedDB database, and removes each cache, then automatically re-scans to show a before-and-after breakdown confirming each category at zero.
The same-origin policy built into every browser prevents any web page, including this one, from reading or deleting storage that belongs to a different domain. A cleaner running on this site can only touch cookies, storage, databases, and caches created for this same domain, and that is exactly the boundary this tool respects; anything more would require a browser extension with elevated permissions. To purge data across all sites at once, use your browser's built-in clearing dialog (Ctrl+Shift+Delete in Chrome and Edge, or the equivalent in Firefox and Safari) and choose a time range plus the cookie and cached-data types. This cleaner is the better choice when you want per-category control, size visibility, and instant verification for a single site.
It identifies and clears cookies (session and persistent), localStorage entries, sessionStorage, IndexedDB databases, service worker caches, and HTTP cache. A typical browsing session accumulates 50-200 tracking cookies and 5-30MB of cached data. One click removes all of it without affecting saved passwords or bookmarks.
Browser "clear history" only removes URLs and basic cookies. This tool goes deeper: it enumerates every localStorage key (where sites store tracking IDs, A/B test assignments, and fingerprinting data), IndexedDB records, and service worker caches that persist across normal clearing. It shows you exactly what each site stored before you delete.
