Stigma. See what's tracking you.

How it works

Three steps between you and a clearer view of the web.

See it

Click the Stigma icon on any site. Get a plain-language list of every tracker watching you, grouped by what they do.

Understand it

Each tracker entry shows the company, the category (advertising, analytics, social, fingerprinting), and the specific types of data it collects from you. No jargon, no infosec terminology.

Do something

Block individual trackers, or block whole categories across every site you visit. Send Global Privacy Control opt-out signals. Clear site data in one click. Every control says exactly what it affects.

How it's different

Visibility first. Honest about the rest.

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 or try to clean up the page. For a full ad-free experience, pair it with a dedicated ad blocker.

Plain language, not jargon.

Stigma describes what companies are doing in words you don't have to translate. No "fingerprinting vectors" or "cross-domain request surfaces." Just who's watching, what they're collecting, and what it's for.

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. The bigger data-rights problems are what we're building toward next.

FAQ

The questions people usually ask.

Is this an ad blocker?

No. Ad blockers exist to remove ads from the page. Stigma exists to show you tracking and block it at the source. Ad infrastructure and tracking infrastructure often overlap, so blocking advertising trackers reduces some ads as a side effect, but removing ads isn't the goal. For a full ad-free experience, run Stigma alongside uBlock Origin.

What about companies like Meta or Google who already have my data?

Stigma can't delete what they already have. What it can do is stop the next layer from forming. Blocking trackers now keeps today's browsing from feeding into the same profile. Pulling back data that's already out there is a bigger problem, and that's what we're working on next.

Does Stigma conflict with my existing privacy tools?

No. Stigma plays well with uBlock Origin, Privacy Badger, Ghostery, and others. If you already run one, Stigma may show fewer trackers on most sites because your other tool stopped them upstream. That's not a bug. It's your stack working.

How is Stigma different from Privacy Badger or Ghostery?

Stigma's core difference is legibility. Other tools block quietly in the background. Stigma makes the tracking visible in plain language, gives you context for each tracker, and treats your understanding as the point rather than the afterthought.

Is it really free? What's the catch?

No catch. Stigma is free. No ads, no upsells, no data collection. If you want to support the work, you can donate. Future privacy tools may introduce paid tiers for advanced data-rights features, but Stigma itself stays free.

What data does Stigma collect?

None. No accounts, no servers, no analytics of any kind. The extension only has access to what happens inside your browser, and nothing about that leaves your machine. The source is on GitHub if you'd like to verify.
