What exactly does the Privacy Cleaner delete?

It scans and deletes five storage categories for the current site: cookies, localStorage, sessionStorage, IndexedDB databases, and Cache Storage entries. The scan shows a live count and estimated size per category, and you untick anything you want to keep — for example a theme preference — before cleaning.

Can it clear data stored by other websites?

No. Browsers enforce the same-origin policy, so a page can only touch storage belonging to the site it runs on. To wipe cookies and site data across all sites, use your browser's built-in settings (Ctrl+Shift+Delete in Chrome and Edge, or the Privacy panel in Firefox and Safari).

Will cleaning storage log me out of websites?

On the current site, very likely yes — login sessions, tokens, and preference flags typically live in cookies and localStorage. If you need to stay signed in, untick Cookies and Local Storage and clean only Cache Storage or SessionStorage, which can usually be removed without breaking your session.

Is any data sent to a server when I scan or clean?

No. Scanning reads your browser's own storage APIs and cleaning invokes their delete methods — every operation happens locally and instantly, with zero bytes leaving your device. The tool works entirely offline.

What browser privacy cleaning actually does — illustrated

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.

Resetting a site's tracking footprint before a handoff

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:Counts cookies, local/session storage keys, IndexedDB stores and cache entries for this site only
Review:Rows show count + estimated size; untick anything you want to keep (e.g. a theme preference)
Clean:Cookies get expiry dates in the past, storages are cleared, databases/caches deleted via their APIs
Re-scan:The tool scans again so you see the live 0-item result instead of guessing

¿Qué borra exactamente el limpiador de privacidad?

Escanea y borra cinco categorías de almacenamiento del sitio actual: cookies, localStorage, sessionStorage, bases de datos IndexedDB y entradas de Cache Storage. El escaneo muestra un recuento en vivo y el tamaño estimado por categoría, y puedes desmarcar lo que quieras conservar —por ejemplo una preferencia de tema— antes de limpiar.

Preguntas frecuentes

¿Puede limpiar datos almacenados por otros sitios web?

No. Los navegadores imponen la política de mismo origen, así que una página solo puede tocar el almacenamiento perteneciente al sitio en el que se ejecuta. Para borrar cookies y datos de sitio en todos los sitios, usa los ajustes integrados de tu navegador (Ctrl+Shift+Delete en Chrome y Edge, o el panel de privacidad en Firefox y Safari).

¿Limpiar el almacenamiento me cerrará sesión en los sitios web?

En el sitio actual, muy probablemente sí: las sesiones de inicio de sesión, los tokens y las marcas de preferencia suelen vivir en cookies y localStorage. Si necesitas mantener la sesión iniciada, desmarca Cookies y Local Storage y limpia solo Cache Storage o SessionStorage, que normalmente se pueden quitar sin romper tu sesión.

¿Se envía algún dato a un servidor cuando escaneo o limpio?

No. El escaneo lee las APIs de almacenamiento propias de tu navegador y la limpieza invoca sus métodos de borrado: cada operación ocurre localmente y al instante, con cero bytes saliendo de tu dispositivo. La herramienta funciona completamente sin conexión.

What browser data does it scan and remove?

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.

How is this different from clearing browser history?

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.
