How It Works

Simple. Transparent. Powerful.

Three steps from install to full privacy control - no accounts, no setup headaches.

📲

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.

📊

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.

🚫

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 hardware-level blocking - Privacy Prime has every angle covered.

🎤

Microphone Monitor & Block

See every app that opens your mic, with timestamps and duration. Soft-mute via AudioManager (Standard) or kill audioserver at hardware level (Pro).

Standard & Pro

📷

Camera Monitor & Block

Detect silent camera access. Block via Device Admin/Device Owner (Standard) or cameraserver kill via root shell (Pro) for bulletproof hardware-level protection.

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.

All Tiers

📋

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.

All Tiers

🔋

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.

All Tiers

🧬

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

Transparency

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.

Read Privacy Policy →

🔒

SQLCipher · AES-256

Activity logs, battery snapshots, app rules - all encrypted at rest.

🗝

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 - Root Users

Boot-Level Protection
with the Magisk Module

Privacy Prime Pro includes a companion Magisk module that re-applies hardware-level mic and camera blocking before the Android framework even starts - so you're protected from the very first second after reboot.

1 Enable mic/camera blocking in the app. The blocking state is written to a local config file.
2 Download the module .zip from within the app.
3 Flash via Magisk Manager and reboot.
4 On every boot, the module reads your config and kills audioserver & cameraserver before Android starts.

Common Questions

Everything you need to know before downloading.

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. The Lite and Standard tiers work on any Android device (Android 9+). Root is required only for Pro-tier hardware-level mic/camera blocking and the Magisk module. The app detects your root status automatically and hides features that aren't available.

On Android 9 and above, camera blocking via Device Admin requires Device Owner - a system-level elevation that requires a one-time ADB command. The app walks you through this with a step-by-step dialog. On rooted devices (Pro tier), camera blocking works without Device Owner by killing the cameraserver process at the hardware abstraction layer.

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. The Lite tier is free forever.

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+.
