In 2023, a family at an amusement park experienced technology's impact on privacy when the park's app used geolocation to notify a waiting parent about fast-track entry. Spanish researchers investigated how apps exploit Bluetooth and Wi-Fi permissions to track users indoors, even without GPS. Their findings, to be presented at the Pets privacy conference, reveal that 86% of 9,976 analyzed Android apps collect sensitive data, including location coordinates. The study highlights ethical concerns regarding data sharing and potential misuse, as information can track individuals' movements and identify sensitive activities. Many apps use software development kits (SDKs) that include hidden location tracking features, with 52 SDKs identified in nearly 10,000 apps installed on around 55 billion devices. The Android Advertising ID allows companies to track users and create detailed profiles based on location data, raising ethical dilemmas about privacy and the commodification of personal information.
