Site Data & Cookies Cleaner does not collect, store, transmit, sell, or share personal data.

All actions are performed locally in the user's browser.

The extension does not use external servers, analytics, tracking, remote code, user accounts, or cloud sync.

It only uses Firefox extension APIs required to:
- detect the active tab domain,
- remove cookies for the current site or a selected domain,
- clear all cookies,
- clear browsing history,
- clear cache.

All actions are performed only when explicitly triggered by the user from the popup.
