Privacy & tracking prevention

Take back control of what gets collected about you

We document how tracking works in forensic detail — which means we can also show you, accurately, how to stop it. This is the practical, regularly-updated playbook for blocking trackers in your browser, on your network, and at the consent layer. No fear-mongering, no affiliate-driven nonsense — just what works in 2026.

Tracking isn’t inherently evil — careless, non-consensual tracking is. So this section does two things at once: it helps you defend yourself, and it names the analytics tools that measure responsibly without harvesting your identity. See the Privacy Scorecard.

Four layers of defense

No single tool is enough. Each layer catches what the others miss; stacked, they remove the large majority of tracking. Start at the top.

01

In the browser

Pick a browser that blocks by default, then turn on the settings that matter — tracking protection, partitioned storage, and the Global Privacy Control signal.

02

With extensions

Content blockers and consent automators. What still works after Manifest V3, what got quietly defanged, and the honest tradeoffs.

03

On the network

DNS filtering, encrypted DNS, and VPNs — device-wide and household-wide protection, plus what each actually hides.

04

Consent & your rights

How consent banners and Consent Mode work, why GPC is now legally binding in much of the US, and how to exercise opt-out and deletion rights.

The model behind tracking prevention.

Tracking Prevention: the Layered Defense Model

What web tracking actually is, what you can realistically block, and the five-layer approach to protecting your data — from browser settings to DNS to behavior.

Browsers

The highest-leverage layer — lock down the engine.

Harden Firefox for Privacy

Enhanced Tracking Protection (strict), Total Cookie Protection, encrypted DNS, URL-parameter stripping, containers, and the about:config keys that matter.

Chrome, Brave, and Edge: the Chromium Privacy Reality

Why Chrome's Privacy Sandbox is not the same as blocking tracking, why Brave is the strongest Chromium option, and how to lock down Edge.

Safari and iOS Privacy

Intelligent Tracking Prevention, App Tracking Transparency, and the iOS settings that limit cross-app and cross-site tracking.

Extensions

Cover the long tail the browser allows through.

The Privacy Extension Stack

uBlock Origin and the Manifest V3 problem, plus Privacy Badger, Consent-O-Matic, ClearURLs, and Cookie AutoDelete — what each one actually does.

Network & DNS

Protect every device on your network.

DNS Blocking, VPNs, and Network-Level Privacy

Pi-hole and AdGuard Home for whole-network ad/tracker blocking, NextDNS, encrypted DNS, and the truth about what a VPN does and doesn't protect.

Consent & signals

The opt-outs that carry legal weight.

Global Privacy Control, Do-Not-Track, and Consent Banners

Why GPC is now legally enforceable, why Do-Not-Track is dead, how to enable the signal, and what 'Reject All' actually does.

Not all tracking is equal

The scorecard grades the tools sites use to collect your data.

If you run a website, you can measure visitors without betraying them. We grade analytics, advertising, and session-replay tools on data minimization, consent honoring, identifier strategy, residency, and transparency. Choose the green ones; understand exactly what the red ones do.

● PRIVACY-FIRST (grade A)

Fathom Analytics, Plausible Analytics, GoatCounter, Matomo, Simple Analytics, Pirsch Analytics — cookieless, no personal data, often no consent banner required.

● HIGH-COLLECTION (grade F)

Google Ads & Floodlight, Meta Pixel & Conversions API, Microsoft Clarity, TikTok Pixel & Events API — built to ship your behavior and identifiers to ad platforms, often server-side.

Inspect before you trust

Want to know what a specific site is doing right now? The free Beacon Decoder and Pixel & Tag Scanner show the actual requests and tags a page fires. For a full, dated audit of a site’s tracking, cookies, and data collection — the kind you can hand to a legal or privacy team — that’s what ad.rip is for.
