Haven: Hayatta Kal

Your phone doesn't have to turn into a brick when networks collapse and the internet goes down.

Haven is a next-generation survival and offline communication terminal that operates with zero internet and base station dependency in earthquake, natural disaster, storm, or wilderness conditions. It transforms your phone's hardware sensors and wireless chips into an independent security center.

📡 OFFLINE MESH CHAT & SOS (Device-to-Device Communication)
Stay connected even when cellular data and base stations are down during a disaster:

Device-to-Device Relay: Creates a chain network between phones via Bluetooth and Wi-Fi; your messages bounce off other devices and are transmitted miles away.

End-to-End Encrypted & Secure: Complete privacy in one-to-one or open channels with X25519 key exchange, Ed25519 digital signature, and ChaCha20 protocol.

Enhanced Data Transmission: Offline voicemail and photo sharing.

Smart SOS Broadcast: Transmit your GPS coordinates and battery level to the entire mesh network with a single touch. Incoming emergency calls alert you with a loud alarm notification, even in silent mode.

⏱️ SMART FIRST AID ENGINE & TCCC PROTOCOL
In moments of panic, time perception is lost, and there is no margin for error. Haven is by your side with its step-by-step decision-making mechanism:

Tourniquet Timer: Memorizes the applied time and gives a critical warning when 2 hours have passed to prevent tissue necrosis and limb loss.

CPR Metronome & Cycle Counter: Metronome and 10-minute compression timer to help you perform chest compressions with the correct rhythm.

11 Critical Medical Protocols: Adult CPR, stopping severe bleeding, Heimlich maneuver, steps for frostbite/hypothermia, burns, fractures, snake/scorpion bites, and stroke.

Visual & Auditory Guidance: Large decision diagrams (Yes/No) and offline Turkish voice guidance that does not require internet.

🗺️ OFFLINE TOPOGRAPHIC MAPS & NAVIGATION
Standard, terrain/relief, and topographic map layers.

Import your own GPX/KML files; route, distance measurement, and track logging.

Military and professional coordinate support: Latitude/Longitude, UTM, and MGRS.

Instantly locate incoming SOS signals on the map.

🌪️ BAROMETRIC STORM PREDICTION & SCENARIO MODES
Offline Pressure Analysis: Calculates the pressure drop over the last 3 hours by reading your phone's barometer sensor, providing advance warning of approaching sudden storms even without a network connection.

Scenario-Based Disaster Mode: "To Do Now" and "Next Steps" checklists for earthquakes, fires, floods, or emergencies.

Emergency Equipment Signals: Visual Morse Code SOS signal with flash, emergency siren, and direction-finding precision compass.
