The extension on a test page

A privacy report card for each website.

Home: the numbers for this website
Trackers: each company, its category, and if PrivacyBrew blocked it.
Details: which companies, and what they do
Settings: switches for trackers, ads, cookie pop-ups and privacy requests.
Settings: one switch for each feature

Report card

Trackers, ads, outside scripts, cookies and fingerprinting. Each with a short line about what it means.

Blocks trackers and ads

Known trackers and ads do not load. Pages often load faster.

Rejects cookie pop-ups

It selects "Reject all" or keeps only necessary cookies. It never selects "Accept all".

Asks websites not to sell your data

It sends Global Privacy Control to each website. In some US states, websites must obey it.

You stay in control

Is a website broken? Turn off blocking for that website only. Each feature has its own switch.

How it works

All checks happen in your browser.

When you open a website, PrivacyBrew checks each request in your browser. It blocks trackers and ads, rejects cookie pop-ups and asks the website not to sell your data. Then it shows a report card.
01 · CHECK

Compare each request with known lists

A tracker list and an ad list ship inside the extension. Nothing is looked up online.

02 · STOP

Block, reject and ask

Chrome stops matched requests. Cookie pop-ups get "Reject". Each website gets a "do not sell" request.

03 · SHOW

Tell you in simple words

The report card shows what happened. Only you see it. It resets when you open a new page.

Why we built it

Ads follow you because trackers follow you.

Trackers on many websites record your visits. Ad companies use that record to choose the ads that you see. Most blockers show only a number. PrivacyBrew also tells you what each tracker is and why it is important.

What it does not do

It does not send your data anywhere. It has no account and no analytics.

It does not keep your browsing history. Each report is for the open page only.

Its limits

It finds known trackers and ads only. It cannot block all video ads.

Some websites can break. Turn off blocking for that website.

Lists: Disconnect tracker list (CC BY-NC-SA 4.0), EasyList. Cookie pop-up rules: DuckDuckGo autoconsent (MPL-2.0).
