SafePhone: Advanced Anti-Theft Protection
SafePhone is a specialized security and emergency assistance program designed to protect your device and private data. By detecting unauthorized access and SIM card swaps in real time, SafePhone ensures you are always aware of your device's status.
Key Security Features
Intrusion Detection: Automatically captures high-quality security photos and ambient audio upon failed unlock attempts to identify unauthorized users.
SIM Protection: Immediate security alerts and automatic device monitoring if an unauthorized SIM card is inserted. Detailed information is sent directly to your designated emergency contact.
Emergency Status Reports: Receive comprehensive security reports, including the device's last known GPS coordinates, directly in your private email when a security breach is detected.
Trusted Zones (Geofencing): Define safe locations where security monitoring automatically adjusts to strike a balance between protection and battery preservation.
Important: Permissions and Privacy Transparency
To ensure reliable protection, even when the device is locked or running in the background, SafePhone requires the following sensitive permissions:
Background Location: Required to include precise coordinates in security alerts, allowing you to locate your hardware even when the app is not actively running in the foreground.
Device Administrator: This permission is used to monitor lock screen attempts and protect the app against unauthorized uninstallation by an intruder.
Foreground Services: Essential for camera, audio, and location monitoring to generate reliable alerts when the screen is turned off.
Microphone and Camera: Used exclusively to capture evidence of unauthorized access during security breaches.
Privacy First
SafePhone operates on a "local-first" principle. Your sensitive data is never stored on third-party servers. All security alerts are sent directly via your own private SMTP configuration. A persistent notification is mandatory to ensure the user is always aware of the active security monitor.
Use SafePhone responsibly and in compliance with local privacy laws.

Sentinella — Secure Communication
Sentinella is a secure communication app designed for users who take privacy and device integrity seriously.
Calls utilize a secure session setup with encrypted signaling, device verification, and encrypted audio transport. Sensitive session data is processed temporarily and automatically deleted upon completion.
🔒 KEY FEATURES
Secure Voice Calls: Real-time audio via WebRTC with encrypted transport between devices.
Protected Session Setup: Signaling is secured using modern cryptography and session verification.
Device Integrity Control: Only supported and verified devices gain access to secure features.
Background Calls: Receive incoming calls even when the app is not actively running in the foreground.
Automatic Session Cleanup: Temporary session data is automatically deleted after a call ends.
Extra Security Layers: Support for anti-tamper hardening, secure storage, and network security.
🛡️ PRIVACY FIRST
Sentinella is designed with data minimization as its core principle. Wherever possible, sensitive data is not stored long-term. Temporary server data is used exclusively for call setup, routing, and verification of secure sessions.
Cryptographic session keys are generated on the devices to establish the secure connection. As a result, Sentinella is engineered to maximize the confidentiality of your conversations.
⚙️ TECHNICAL SECURITY
Encrypted signaling and session verification
WebRTC for direct audio connections with encrypted transport
Google Play Integrity API for device verification
Secure storage of app secrets on the device
Temporary backend processing for session coordination
Automatic purge of handshake and session data
Sentinella is built for users who view privacy not as an option, but as a requirement.
Decentralized, peer-to-peer (P2P) communication tool
Stay Connected When the Grid Fails.
Lumen Mesh is a decentralized, peer-to-peer (P2P) communication tool. Whether you are in the wilderness, attending a crowded event, or preparing for network blackouts, Lumen Mesh keeps you communicating when traditional networks are unavailable.
No internet, no cell towers, and no SIM card required.
By utilizing your device's built-in Bluetooth and Wi-Fi Direct capabilities, Lumen Mesh links smartphones together to form a resilient, self-healing mesh network. Messages hop from device to device until they reach their destination.
🛡️ ZERO TRUST, MAX SECURITY
Privacy is the baseline. Lumen Mesh does not use cloud servers, requires no phone number, and asks for no email registration. All communications are secured using AES-256-GCM encryption and Elliptic Curve Diffie-Hellman (ECDH) key exchanges. Your data never leaves the mesh and remains stored only on your device inside an encrypted local database.
⚡ CORE FEATURES
Offline Messaging: Send secure text messages to nearby nodes in the mesh network.
Image Transmission: Share critical photos locally without a data plan.
Decentralized Architecture: No central servers or single points of failure.
Auto-Routing: Messages automatically hop across intermediate devices to extend range.
No Accounts Required: Select an Operator Alias and start communicating immediately.
🎯 INTENDED USE:
Outdoor Exploration: Hiking, skiing, and off-roading in zero-coverage areas.
Large Events: Communicate with your group when crowds overload local cell towers.
Tactical Coordination: Coordinate securely in the field without relying on public radio frequencies.
Emergency Preparedness: Stay connected with neighbors during severe weather or power outages.
💎 ADVANCED TACTICAL FEATURES
Advanced capabilities are available for specialized operations:
Background Service: Maintain the mesh network while the app is minimized. Receive incoming messages and relay data for others even when the screen is locked.
Stealth Mode: Obfuscate your Node ID from public broadcasts and rotate cryptographic footprints to maximize Operational Security (OPSEC).
Custom Network Keys: Create a private, isolated subnet. Only devices utilizing your exact Pre-Shared Network Key can join or decrypt traffic, protecting from unauthorized bridging.
⚠️ IMPORTANT NOTE ON PERMISSIONS:
To utilize Bluetooth and Wi-Fi Direct for P2P connections, the Android operating system requires the "Location" and "Nearby Devices" permissions to be granted. Lumen Mesh does NOT track, store, or share your GPS location. The permission is used by the OS solely to discover other devices in your physical proximity.
