A recent investigation revealed a massive geolocation data leak from Gravy Analytics, involving over 2000 apps secretly collecting user location data. The author discovered their precise location data was sent through requests, even with location services disabled. They explored real-time bidding (RTB) and OpenRTB protocols, shocked by the amount of data shared. Unity Ads and Facebook were among those receiving data without adequate consent. Despite attempts, the author couldn't buy their data from brokers due to high costs. The investigation highlights major privacy concerns in the digital advertising ecosystem.
