What is Privacy Badger?

Privacy Badger is a Chrome extension developed by the EFF. It's an automatic blocker that learns and blocks invisible trackers, offering enhanced internet privacy. It achieves this by sending 'Global Privacy Control' and 'Do Not Track' signals and opts users out of data sharing and selling. In addition, it replaces potential trackers with click-to-activate placeholders, removes outgoing link click tracking on social media platforms, and continues to develop more privacy protections. Notably, Privacy Badger does not share user browsing data unless the user chooses to share it.

Summary

Instead of keeping lists of what to block, Privacy Badger automatically discovers trackers based on their behavior. Privacy Badger sends the Global Privacy Control signal to opt you out of data sharing and selling, and the Do Not Track signal to tell companies not to track you. If trackers ignore your wishes, Privacy Badger will learn to block them.

Besides automatic tracker blocking, Privacy Badger replaces potentially useful trackers (video players, comments widgets, etc.) with click-to-activate placeholders, and removes outgoing link click tracking on Facebook and Google, with more privacy protections on the way.

*** Why does Privacy Badger need to read and change all my data on the websites I visit? ***

When you install Privacy Badger, your browser warns that Privacy Badger can “read and change all your data on the websites you visit”. You are right to be alarmed. You should only install extensions made by organizations you trust.

Privacy Badger requires these permissions to do its job of automatically detecting and blocking trackers on all websites you visit. We are not ironically (or unironically) spying on you. For more information, see our Privacy Badger extension permissions explainer: https://github.com/EFForg/privacybadger/blob/master/doc/permissions.md

Note that the extension permissions warnings only cover what the extension has access to, not what the extension actually does with what it has access to (such as whether the extension secretly uploads your browsing data to its servers). Privacy Badger will never share data about your browsing unless you choose to share it (by filing a broken site report). For more information, see EFF’s Privacy Policy for Software: https://www.eff.org/code/privacy/policy
