Abstract - The growing number of Android applications has made permission management a major privacy concern. Most apps request access to sensitive resources such as camera, location, microphone, contacts, and storage, often more than they actually need. AlthoughAndroid provides runtime permissions since version 6.0, users frequently grant them without fully understanding the risks. This leads to over-privileged apps and potential data misuse. In this final-year project, we developed an Android-based smart permission system thatautomatically scans installed applications, identifies dangerous permissions, calculates a simple risk score, and gives clear, actionable recommendations to the user. The system was built using Kotlin in Android Studio and runs entirely on the device using the PackageManager API. No internet connection or external servers are required. We tested the system on 50 real applications collected fromdifferent categories (social media, utilities, productivity). The results show that 22 % of the apps were high-risk, 38 % medium-risk, and 40 % low-risk. The analysis completes in under 400 ms even for 50 apps, making it fast enough for daily use. Users receive simple suggestions such as “Revoke storage permission” or“Review this app before use.” Our work demonstrates a  practical, lightweight solution that helps normal users manage permissions without needing technical expertise. It improves privacy awareness and reduces the chance ofdata leakage on Android devices.
