The Lumen Privacy Monitor
Lumen analyzes your app's traffic and allows you to stay on control over your app's communication patterns.
Lumen reveals how your mobile apps communicate with tracking services and how they collect sensitive personal information about you. Lumen does not require root permissions and works even on encrypted traffic for most Android versions. In the new version, you can also have a direct access to block undesired flows for a given app and also to configure app permissions to better stay in control over who has access to your personal data.
Lumen is an academic research project led by the International Computer Science Institute (ICSI), UC Berkeley and IMDEA Networks to illuminate the mobile ecosystem with real user input. It is sponsored by the NSF (National Science Foundation) and the Data Transparency Lab.
Lumen is available on Google Play.
