Supreme AdBlock — Privacy Policy

Supreme AdBlock is built to protect your privacy, not to collect data.

What we collect

Nothing. The extension has no analytics, no telemetry and no accounts. We do not see which sites you visit, and no browsing data ever leaves your device.

What is stored locally

Kept only in your browser's local storage, never transmitted:

• Whether protection is on or off
• Your allowlisted sites
• Feature toggles (cookie banners, anti-adblock, Meta posts, theme)
• Elements you hid manually with the picker
• A local counter of how many ads were blocked

You can clear all of it from the extension's settings, or by removing the extension.

Network requests we make

One, and only for filter updates. About once a day the extension downloads a small filter file (filters.json) from adblock.carbonstealth.eu so blocking stays current as ad networks and sites change. This request contains no information about you — no identifiers, no browsing data. It is a plain GET of a public file, treated purely as data (block rules and CSS selectors); no downloaded code is ever executed. You can turn auto-update off in the settings.

Permissions

• declarativeNetRequest — block ad/tracker requests via rules.
• storage — save your settings locally.
• tabs — show the per-tab blocked count and current site in the popup.
• alarms — schedule the daily filter update and the pause timer.
• contextMenus — the right-click "Block an element here" entry.
• host access (<all_urls>) — apply blocking on the pages you visit. Page content is processed locally and never sent anywhere.
