Stigma Privacy di Usual Systems

See what's tracking you.

Stigma is a privacy extension that makes tracking visible, in plain language, and lets you do something about it. Open source, 100% local, honest about what it does and doesn't do.

WHAT STIGMA DOES

• Lists every tracker active on the page you are currently viewing
• Labels each one by company, product, category, and the specific types of data it collects
• Lets you block individual trackers or whole categories across every site
• Sends Global Privacy Control opt-out signals to sites that honor them
• Clears cookies and site data in one click
• Runs entirely in your browser. No accounts, no servers, no telemetry

WHY IT'S DIFFERENT

Most privacy tools pick a lane: block everything quietly, or explain everything at length. Stigma does neither. It shows you exactly what's happening, in language you can read, and lets you decide.

• Blocks tracking, not ads. When you block advertising trackers, some ads may fail to load as a side effect, but Stigma doesn't hide empty slots. For a full ad-free experience, pair it with a dedicated ad blocker.
• Plain language, not jargon. No "fingerprinting vectors" or "cross-domain request surfaces." Stigma describes what companies are doing in words you don't have to translate.
• Honest about limits. No tool can delete data companies already have or claw back profiles that brokers have already sold. What Stigma does is make today's tracking visible and stop new collection from piling on.

PRIVACY

Stigma collects no user data. No accounts, no servers, no telemetry. The extension runs entirely in your browser, ships with its tracker database built in, and does not communicate with any external service during normal operation. The full source code is public on GitHub, and you are welcome to audit it.
