<p>TrackerControl allows users to monitor and control the widespread, ongoing, hidden data collection in mobile apps about user behaviour ('tracking').</p><p>To detect tracking, TrackerControl combines the power of the Disconnect blocklist, used by Firefox, and our in-house blocklist is used, created from analysing <i>~2 000 000</i> apps! Additionally, TrackerControl supports custom blocklists.</p><p>This approach</p><ul><li>reveals the companies behind tracking,</li><li>allows to block tracking selectively, and</li><li>exposes the purposes of tracking, such as analytics or advertising.</li></ul><p>The app also aims to educate about your rights under Data Protection Law, such the EU General Data Protection Regulation (GDPR).</p><p>Under the hood, TrackerControl uses Android's VPN functionality, to analyse apps' network communications <i>locally on the Android device</i>. This is accomplished through a local VPN server, to enable network traffic analysis by TrackerControl.</p><p>No root is required, other VPNs or Private DNS are not supported. No external VPN server is used, to keep your data safe! TrackerControl even protects you against <i>DNS cloaking</i>, a popular technique to hide trackers in websites and apps.</p><p>TrackerControl will always be free and open source, being a research project.</p>
