• App Tracking Protection is now open for all Android users. It’s a beta feature in DuckDuckGo for Android that helps block 3rd-party trackers in your apps, even when you’re not using them.
• New since the waitlist beta launch: you can see what personal data trackers are typically trying to collect before we block them (like your precise location, age, and a digital fingerprint of your phone). We’ve also improved performance, reduced app exclusions, and made our blocklist publicly available.
• Start blocking 3rd-party trackers in your Android apps today: update to the latest version of the DuckDuckGo Android app, open Settings and select “App Tracking Protection” (under More from DuckDuckGo section), and follow the onscreen instructions.

App Tracking Protection for Android is launching into open beta today. It’s a free feature in the DuckDuckGo Android app that helps block 3rd-party trackers in the apps on your phone (like Google snooping in your weather app) – meaning more comprehensive privacy and less creepy targeting.
