Privacy Prime monitors every app that touches your microphone, camera, and location -
and lets you block them instantly. No accounts, no analytics, no compromise.
Three steps from install to full privacy control - no accounts, no setup headaches.
01
📲
Install & Grant Permissions
Download from Google Play. Grant PACKAGE_USAGE_STATS once in system settings - that's all Privacy Prime needs to see which apps are spying.
02
📊
Monitor in Real Time
The background service tracks every app that accesses your mic, camera, GPS, or clipboard. A colour-coded live feed shows you exactly what's happening - right now.
03
🚫
Block & Schedule
Tap once to block an app permanently, set a timed schedule, or create a Privacy Profile that you switch in and out throughout the day.
Features
Everything You Need to Stay Private
From real-time monitoring to a live Privacy Score, Permission Inspector, scheduled blocks and Device Owner camera blocking - Privacy Prime has every angle covered. No root required.
🎤
Microphone Monitor & Block
See every app that opens your mic, with timestamps and duration. System-wide soft-mute via AudioManager plus an exclusive VOICE_COMMUNICATION AudioRecord session that silences background spy apps. Works on every device without root.
Standard & Pro
📷
Camera Monitor & Block
Detect silent camera access. Standard holds an exclusive Camera2 session that any covert opener fails against. Pro adds Device Owner enforcement (one-time ADB command) for a true OS-level camera block on Android 9+ — no root, no Magisk.
Standard & Pro
📍
GPS Location Log
Full timeline of which apps requested your location, when, and how often. Colour-coded severity indicators make it easy to spot suspicious patterns.

📋
Clipboard Monitor
Know whenever an app reads your clipboard - a common vector for data exfiltration. Clipboard contents are never stored; only the access event is logged.
Standard & Pro
🔋
Battery Drain Analyser
Hourly snapshots reveal which apps are silently consuming battery in the background - a key signal that something is running when it shouldn't be.
All Tiers
📅
Scheduled Blocking
Set precise time-based rules - block all mic access overnight, allow camera only during work hours, auto-restore on a schedule. Fires with exact alarms.
Standard & Pro
🎨
Privacy Profiles
Save named configurations (e.g. "Travel", "Work", "Sleep") and switch your entire blocking setup in one tap. Stored locally in your encrypted database.
Standard & Pro
🔍
Security Scanner
Scans your installed apps for known high-risk packages, excessive permissions, and unusual permission combinations. Highlights risks at a glance.
Standard & Pro
🧬
Biometric App Lock
Lock the entire app and all blocking controls behind your fingerprint or face ID. Keys never leave the device's secure enclave.
Standard & Pro
📊
Privacy Score
A live 0–100 gauge on the Home screen that summarises your privacy posture in one number. Tap to open the detail screen with What's helping / hurting, Quick Wins suggestions, and a built-in user guide (band meanings, tips, FAQ).
Standard & Pro
🔎
Permission Inspector
"Who has access to what?" — every installed app grouped by the dangerous permissions it holds (Camera, Mic, Location, Contacts, SMS, Storage…). Tap a permission to see the granting apps, tap an app to revoke in system settings.
Standard & Pro
🔔
Recent Alerts Feed
Settings → Security & Access → Recent Alerts. A 7-day chronological feed of background access events and blocked-rule hits, colour-coded so unusual activity stands out at a glance.

Every Permission, Explained
We believe you deserve to know exactly why each permission is requested - and what it's used for.
📊
PACKAGE_USAGE_STATS
Detects which apps access your mic, camera, and GPS. The core of all monitoring. Granted manually by you in system settings.
🎤
RECORD_AUDIO
Holds an exclusive audio session to physically prevent spy apps from recording. Audio is never captured, stored, or transmitted.
📷
CAMERA
Holds an exclusive Camera2 session to block silent access. No photos or video are ever captured.
🔔
POST_NOTIFICATIONS
Sends an alert when a blocked app attempts to access your mic, camera, or GPS. Android 13+ only, optional.
📦
QUERY_ALL_PACKAGES
Lists installed apps for the security scanner and app blocking rules. No data leaves the device.
⏰
SCHEDULE_EXACT_ALARM
Fires scheduled blocking rules at the precise times you configure. Required for time-based privacy profiles.
🌐
INTERNET
Used only to fetch app descriptions from the Play Store for the detail sheet, and to process in-app purchases via Google Play Billing. No personal data sent.
🔄
RECEIVE_BOOT_COMPLETED
Restarts protection services after a reboot so you're always covered - even after your device restarts overnight.
Security Architecture
Zero Data Leaves Your Device
Privacy Prime was built from the ground up on one principle: your data is yours. Every byte stays on your hardware.
🔐
Activity logs stored in an AES-256 encrypted SQLite database via SQLCipher - unreadable without your device credentials.
🗝
All encryption keys live in the Android Keystore hardware enclave. They cannot be extracted, exported, or read by any app - including ours.
🛑
No analytics SDK, no crash reporter, no telemetry of any kind. We literally have no way to see your data.
📵
The app works completely offline. Internet is only used for Google Play Billing and optional app-name lookups - both are network calls you can inspect.
Activity logs, battery snapshots, app rules - all encrypted at rest. The database key is wrapped by a hardware-backed Keystore key; the plaintext key never enters Java String heap.
🗝
Android Keystore
Encryption keys stored in hardware-backed secure enclave. Never exportable.
🧬
Biometric Lock
Fingerprint / Face ID required to open the app. Backed by BIOMETRIC_STRONG.
🛡
EncryptedSharedPreferences
All settings and blocking state encrypted via Google Jetpack Security (AES-256-GCM).
⚙️ Pro - One-time ADB setup
OS-Level Camera Block via Device Owner
Privacy Prime Pro provisions itself as Android Device Owner — the same OS policy MDM apps use in enterprise — to enable DevicePolicyManager.setCameraDisabled(true). The camera block lives at the OS layer, survives reboot, and no app can bypass it. No root, no Magisk, no warranty impact.
1 Enable USB debugging in your phone's Developer Options.
2 Install Android platform-tools on a computer (one-time download).
3 Connect the phone over USB and run a single adb command.
4 Open the app — Pro's Device Owner camera block is now active.
No. Privacy Prime does not run any servers, collect any telemetry, or have any way to access your data. Everything the app generates - activity logs, blocking state, battery data - is stored exclusively on your device in an AES-256 encrypted database.
No — and Pro no longer uses root. Free, Standard, and Pro all run on stock Android 9+. Standard's mic/camera blocking (system-wide soft-mute, exclusive AudioRecord, Camera2 exclusive session) works on every device with no setup. Pro adds an OS-level Device Owner camera block that's provisioned by a single one-time adb command — the same policy enterprise MDM apps use. No root, no Magisk, no warranty impact.
Standard holds an exclusive Camera2 session — any background app that tries to open the camera receives ERROR_CAMERA_IN_USE and fails. Pro adds DevicePolicyManager.setCameraDisabled(true) via Device Owner, which is a true OS-level block enforced by Android itself and persists across reboot. Pro's setup runs once from a computer (adb shell dpm set-device-owner …) and the in-app guide walks you through it step by step.
Yes — as a launch promotion. After you finish the intro and grant the Lite-tier permissions, the app offers you a user-activated 7-day Standard trial from a prompt on the Home screen. No card, no Google account dance. Tap Start trial and the timer begins; tap Not now and the prompt reappears next time you open the app. When the 7 days end you drop to Free (Lite) and can purchase Standard or Pro at any point. Anti-tamper: the trial state lives in a small Auto-Backup-eligible preferences file, so a Clear Data / reinstall on the same Google account doesn't reset it, and a cross-reboot accumulator means clock rollback can't extend it either. This launch-promo trial may be removed in a future release.
Apps that genuinely need the mic or camera will fail to open them while blocking is active - which is the intended behaviour. You can whitelist specific apps, set a schedule so blocking is only active at certain times, or use Privacy Profiles to switch between configurations instantly.
All data is stored in the app's private storage directory. Uninstalling the app removes all locally stored data - there is nothing on any server to delete, because nothing was ever sent there.
No. Standard ($4.99) and Pro ($9.99) are one-time in-app purchases via Google Play. You pay once and own that tier permanently — no recurring billing, no feature expiry, no surprises. Every new install also gets a 7-day Standard trial automatically, with no card. Free (Lite) is permanent for anyone who never upgrades.
A live 0–100 gauge at the top of the Home screen that summarises your privacy posture in one number. It combines biometric lock state, mic/camera lock state, active block rules, scheduled blocks, the active privacy profile, dangerous-tracker count from Cookie Scan, and recent background-access volume. Tap the gauge to open a dedicated detail screen with What's helping / hurting factor lists, Quick Wins suggestions, band-meaning legend, Privacy Tips, and an expandable FAQ. The score is computed entirely on-device. Privacy Score, Security Scanner, and the Clipboard Monitor are Standard and Pro features — Free (Lite) shows a simplified Home dashboard without the gauge.
Yes - to provide real-time monitoring, Privacy Prime runs a foreground service that Android shows as an ongoing notification. This ensures it isn't killed by battery optimisation. You can configure the app to start automatically on boot. The battery impact is minimal as the service is event-driven, not polling.
Privacy Prime requires Android 9 (API 28) or higher. It is tested and fully supported up to Android 14 / 15 (API 35/36). Certain features (like the Quick Settings tile and exact alarms) require Android 12+.
Take Back Your Privacy Today
Install free, finish the intro, grant the Lite permissions, and you'll be offered a 7-day Standard trial right on the Home screen — no card, no account, no risk. Drop to Free (Lite) when the trial ends, or upgrade once for life.
