TrustGuard
Advanced privacy & security for Android — entirely on your device.
TrustGuard is a comprehensive Android security and privacy companion. Every operation runs locally on the phone — no data leaves the device, no remote analytics, no telemetry. Distributed outside Google Play because the features it offers don't fit Play Store policy. Partially open-source.
Why TrustGuard
100% on-device.
- Runs entirely on your phone — your data is never sent to a remote server, ever.
- No ads, no tracking, no data sales.
- Every feature is free and unmetered.
- Designed by an independent developer with privacy as a non-negotiable.
- Continuous updates and new feature support.
Privacy & network protection.
The core of TrustGuard — block what you don't want before it leaves the device.
DNS-level ad & tracker blocking
Local-VPN technology blocks ad networks, tracking SDKs, and known malicious domains at the device level — across every app. Multi-fallback DNS via Cloudflare, Google, and Quad9. Per-app filtering: choose what gets protected.
App firewall
Control Wi-Fi and mobile data access for every installed app, separately. Catch apps quietly phoning home in the background. VPN-integrated packet-level traffic inspection.
AES-256 encrypted vault
Military-grade AES-256-GCM file encryption with PBKDF2 key derivation (100,000 iterations) and password protection. Photos, documents, video — anything you don't want on the public file system.
Decoy identity engine
Randomized device-fingerprint generator: IMEI, MAC, Android ID, serial, build fingerprint. Pairs with Xposed/Magisk modules. One-tap new identity, copy-to-clipboard.
Packet monitor
Real-time view of how much data each app sends and receives. Upload/download breakdown, packet counts, traffic summaries. Catch the silent uploaders.
Bloatware cleaner
Detects carrier-, OEM-, and pre-installed bloatware. Categorized (Carrier, OEM, Google, Social). One-tap to uninstall or disable.
Family & oversight.
Parental controls and granular privacy tooling that doesn't ship your kids' usage data to the cloud.
Family Shield — parental controls
PIN-protected parent dashboard, multi-child profiles. App blocking, screen-time limits, age-aware automatic filtering. Live notifications when a new app is installed; auto-block of adware. Category filters (social, gambling, dating). Weekly usage reports and safe-search.
Privacy tools
Clipboard guard — see which apps read your clipboard. Camera/microphone access tracker. Per-app tracker map showing which ad/analytics SDKs are inside your apps. Location, camera, mic permission stats.
Advanced security.
Risk analysis, malware detection, Wi-Fi audits, and device hardening — all working offline.
APK risk analysis
Security risk score for every installed app — debug mode, cleartext traffic, backup permission, sideload vs Play. Developer-options security warnings. USB/ADB protection state. Military-grade DoD 3-pass file shredder.
Offline malware scanner
Malware, spyware, and trojan detection — fully offline. Signatures shipped with the app, no upload of your files anywhere.
Wi-Fi security audit
Encryption type, signal strength, network risk evaluation. Spot the open and WEP networks before joining them.
App integrity check
Sideload detection, signature verification — catch tampered installs before they run.
And then some.
A handful of smaller tools that didn't deserve their own headline but earn their place on a privacy-conscious phone.
Battery health
Top-consumer apps and battery health stats.
Storage analyzer
Visual storage breakdown — find the duplicates and large files.
Network monitor
Live traffic analysis.
File recovery
Recover deleted photos, video, and documents.
Device optimizer
Clear temp files, duplicate photos, and oversized leftovers.
Distribution
Why TrustGuard isn't on Google Play.
TrustGuard ships outside Google Play because some of its features — local-VPN tracker blocking, per-app firewall, fingerprint randomization — are not compatible with Play Store distribution policy. It is designed for users who understand what they are installing. To install, enable installs from unknown sources for your browser, download the APK from the official source, and verify the signature.
