Permission Manager Overview
Navigate to Settings → Privacy → Permission Manager to audit which apps access your camera, microphone, location, and contacts. Revoke anything unnecessary.

Set location access to "While using the app" or "Ask every time" — never "Allow all the time" for social media, shopping, or entertainment apps.
PCAPdroid Network Monitor
Install PCAPdroid from the Google Play Store to capture and analyze network traffic. No root required — see exactly which apps are connecting and where your data goes.
