Vanish is built with user privacy as a core requirement. This Privacy Policy outlines how data is handled by the Firefox Add-on.

1. Zero Data Collection
   Vanish does NOT collect, log, store, transmit, or sell any personal data, browsing history, user credentials, or IP addresses to any external server or third party.
2. Mozilla Data Collection Disclosure
   In accordance with Mozilla’s Add-on Policies, Vanish explicitly declares:
   "data_collection_permissions": { "required": ["none"] }
   The add-on requires no personal data to function and collects zero user data.
3. Local Firefox Storage Only
   Your preferences (such as idle delay time, theme mode, and custom domain list) are saved locally using Firefox’s native browser.storage.sync API. This data stays entirely within your local browser profile or Firefox Sync account.
4. No External Requests or Trackers
   Vanish operates completely offline inside your browser. It contains zero analytics, tracking scripts, or external network requests.
