Privacy Ad Blocker

About

Privacy Ad Blocker is a Chrome extension that blocks ads and trackers without ever seeing your browsing history. Built on Chrome's Manifest V3 declarativeNetRequest API, the extension hands a list of rules to Chrome and Chrome does all the blocking internally. The extension itself has zero network access and zero visibility into your browsing.

How It Works

Unlike traditional ad blockers that inject scripts into every page and monitor your web traffic, Privacy Ad Blocker takes a fundamentally different approach:

• Chrome does the blocking — the extension provides rules, Chrome enforces them natively
• No content scripts — nothing injected into your pages
• No background processes — no persistent scripts running
• No host permissions — cannot read any page content or URLs
• No network access — cannot phone home or send analytics

What It Blocks

• Google Analytics & Google Ads (DoubleClick)
• Facebook Pixel & tracking
• Criteo ad network
• Generic ad serving domains
• More rules added regularly

Installation

Privacy Ad Blocker is available as an unpacked Chrome extension. To install:

1. Download or clone the extension from GitHub
2. Open chrome://extensions/ in Chrome
3. Enable Developer mode (top right toggle)
4. Click Load unpacked and select the adblock-privacy-ext folder

Open Source

This extension is open source and free to use. The entire codebase is transparent — you can verify every rule and confirm there's no hidden tracking.

Privacy Policy

We collect nothing. The extension has no ability to see what sites you visit, what you type, or anything else. It gives Chrome a list of domains to block. That's it. There is no analytics, no telemetry, no data collection of any kind.
