Permissions Summary vs PilferShush Jammer
Side-by-side comparison of two open source alternatives
Permissions Summary
Permission Summary is a lightweight, open source Android app that helps you quickly check which apps have access to sensitive permissions on your device — in just a few seconds.The app only lists user-installed apps and only those with dangerous permissions. These are permissions Android classifies as potentially privacy-invasive and require explicit runtime approval.Permissions Checked:Camera — Access to your device's cameraMicrophone — Record audioLocation — Fine & coarse location (GPS, Wi-Fi, etc.)Storage — Access to files, media, photos, or musicContacts — Read, write, or access contact data and accountsCalendar — Read or write calendar eventsPhone / Call Log — Read phone state, call logs, answer calls, etc.SMS — Send or receive SMS, MMS, and WAP push messagesBody Sensors — Access data from heart rate, step counter, etc.Non-dangerous permissions like INTERNET, POST_NOTIFICATIONS, and BLUETOOTH are intentionally excluded to reduce noise.Features:🔐 Grouped by Permission — Instantly see which apps request access to camera, mic, contacts, etc.🧼 User Apps Only — Filters out system apps and background clutter.🚫 Focus on Privacy — Shows only dangerous permissions and skips non-sensitive ones.📱 Modern UI — Built entirely with Jetpack Compose and Material 3.⚡ Fast & Lightweight — Optimized for quick, offline use. No trackers, no nonsense.Privacy: Everything runs locally on-device and offline. No personal data is collected or shared.
PilferShush Jammer
Features a passive jammer technique that engages the microphone thereby blocking other apps from using it. But does NOT listen to or record any of the audio from the microphone. It uses 0% CPU and no noticeable battery use. However is not intended to be left on permanently due to the variety of triggers that can cause audio_focus_state changes (VOIP etc). Also features an active jammer that emits tones constrained to the NUHF range of 18 kHz to 24 kHz range. User determined carrier frequency and drift limits with rate for random tone emissions depending on the device capabilities. For instance 20000 Hz carrier, drift limit 1000 Hz and rate slow - will output random frequency between 19 kHz and 21 kHz approximately every second. Audible artifacts are present during the NUHF tones but this may be changed in a future release. Experimental white noise output may not be very effective at blocking and is a somewhat annoying sound. The device speaker output may not have enough amplitude to block unwanted NUHF signals - testing will determine. * Manual start * Notification post when running * Auto stop and restart when telephony interrupts * Currently relies on audio_focus_state changes for auto-switching * Active jammer
