Forensic analysis for HRW found that Ruangguru collects students’ precise location, Android advertising ID, device information and in-app navigation, and transmits them to AppsFlyer and Facebook. The app also has the ability to access call logs, camera and microphone. Its privacy policy says it combines data it holds on students with information from other sources for advertising and other purposes. AppsFlyer told HRW it does not sell or serve ads, build targeting profiles or sell data, and did not address the questions about Ruangguru specifically.
