Online Tracking is Out of Control—Privacy Badger Can Help You Fight Back

EFF update

3 days 4 hours ago

Every time you browse the web, you're being tracked. Most websites contain invisible tracking code that allows companies to collect and monetize data about your online activity. Many of those companies are data brokers, who sell your sensitive information to anyone willing to pay. That’s why EFF created Privacy Badger, a free, open-source browser extension used by millions to fight corporate surveillance and take back control of their data.

Since we first released Privacy Badger in 2014, online tracking has only gotten more invasive and Privacy Badger has evolved to keep up. Whether this is your first time using it or you’ve had it installed since day one, here’s a primer on how Privacy Badger protects you.

Online Tracking Isn't Just Creepy—It’s Dangerous

The rampant data collection, sharing, and selling fueled by online tracking has serious consequences. Fraudsters purchase data to identify elderly people susceptible to scams. Government agencies and law enforcement purchase people’s location data and web browsing records without a warrant. Data brokers help predatory companies target people in financial distress. And surveillance companies repackage data into government spy tools.

Once your data enters the data broker ecosystem, it’s nearly impossible to know who buys it and what they’re doing with it. Privacy Badger blocks online tracking to prevent your browsing data from being used against you.

Privacy Badger Disrupts Surveillance Business Models

Online tracking is pervasive because it’s profitable. Tech companies earn enormous profits by targeting ads based on your online activity—a practice called “online behavioral advertising.” In fact, Big Tech giants like Google, Meta, and Amazon are among the top companies tracking you across the web. By automatically blocking their trackers, Privacy Badger makes it harder for Big Tech companies to profit from your personal information.

Online behavioral advertising has made surveillance the business model of the internet. Companies are incentivized to collect as much of our data as possible, then share it widely through ad networks with no oversight. This not only exposes our sensitive information to bad actors, but also fuels government surveillance. Ending surveillance-based advertising is essential for building a safer, more private web.

While strong federal privacy legislation is the ideal solution—and one that we continue to advocate for—Privacy Badger gives you a way to take action today.

Privacy Badger fights for a better web by incentivizing companies to respect your privacy. Privacy Badger sends the Global Privacy Control and Do Not Track signals to tell companies not to track you or share your data. If they ignore these signals, Privacy Badger will block them, whether they are advertisers or trackers of other kinds. By withholding your browsing data from advertisers, data brokers, and Big Tech companies, you can help make online surveillance less profitable.

How Privacy Badger Protects You From Online Tracking

Whether you're looking to protect your sensitive information from data brokers or simply don’t want Big Tech monetizing your data, Privacy Badger is here to help.

Over the past decade, Privacy Badger has evolved to fight many different methods of online tracking. Here are some of the ways that Privacy Badger protects your data:

Blocks Third-Party Trackers and Cookies: Privacy Badger stops tracking code from loading on sites that you visit. That prevents companies from collecting data about your online activity on sites that they don’t own.
Sends the GPC Signal to Opt Out of Data Sharing: Privacy Badger sends the Global Privacy Control (GPC) signal to opt out of websites selling or sharing your personal information. This signal is legally binding in some states, including California, Colorado, and Connecticut.
Stops Social Media Companies From Tracking You Through Embedded Content: Privacy Badger replaces page elements that track you but are potentially useful (like embedded tweets) with click-to-activate placeholders. Social media buttons, comments sections, and video players can send your data to other companies, even if you don’t click on them.
Blocks Link Tracking on Google and Facebook: Privacy Badger blocks Google and Facebook’s attempts to follow you whenever you click a link on their websites. Google not only tracks the links you visit from Google Search, but also the links you click on platforms that feel more private, like Google Docs and Gmail.
Blocks Invasive “Fingerprinting” Trackers: Privacy Badger blocks trackers that try to identify you based on your browser's unique characteristics, a particularly problematic form of tracking called “fingerprinting.”
Automatically learns to block new trackers: Our Badger Swarm research project continuously discovers new trackers for Privacy Badger to block. Trackers are identified based on their behavior, not just human-curated blocklists.
Disables Harmful Chrome Settings: Automatically disables Google Chrome settings that are bad for your privacy.
Easy to Disable on Individual Sites While Maintaining Protections Everywhere Else: If blocking harmful trackers ends up breaking something on a website, you can disable Privacy Badger for that specific site while maintaining privacy protections everywhere else.

All of these privacy protections work automatically when you install Privacy Badger—there’s no setup required! And it turns out that when Privacy Badger blocks tracking, you’ll also see fewer ads and your pages will load faster.

You can always check to see what Privacy Badger has done on the site you’re visiting by clicking on Privacy Badger’s icon in your browser toolbar.

Fight Corporate Surveillance by Spreading the Word About Privacy Badger

Privacy is a team sport. The more people who withhold their data from data brokers and Big Tech companies, the less profitable online surveillance becomes.
