This paper presents PrivacyBuddy, an innovative Android privacy dashboard designed to detect excessive data collection, focusing on location data. It addresses the growing concern over apps that collect more personal information than necessary, often leading to privacy violations. Current Android privacy dashboards are inadequate, lacking effective visualizations and insights into app behavior. PrivacyBuddy enhances user awareness by providing intuitive visualizations of data collection frequency, volume, and type, along with a Privacy Score for each app. The dashboard employs user-centered design principles to cater to diverse user needs, from casual users to privacy-conscious individuals. Key features include detailed tracking of location requests, distinguishing between foreground and background access, and offering actionable insights for users to manage their privacy settings effectively. A secure implementation extends the Android OS to monitor data requests made by other apps. A user study validates the design, demonstrating improved usability and user engagement compared to existing solutions. This work contributes to the field of visual data analytics by merging design principles with practical applications, ultimately empowering users to take control of their data privacy in an increasingly data-driven world.
