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

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.
