## What is SignalFlare?

When the world disconnects, SignalFlare lights the way.

Whether you're skiing in the backcountry, hiking off the grid, caught in a natural disaster with collapsed cell towers, or lost in a crowded festival—SignalFlare keeps you connected when traditional cellular networks and Wi-Fi completely fail.

SignalFlare requires no servers, no SIM cards, and zero internet connection. It harnesses your device's built-in proximity technologies (Bluetooth & Wi-Fi Direct) to instantly weave you and nearby users into a resilient, decentralized offline mesh network.

Key Features:
·  Offline Radar & Discovery: Scan your physical surroundings to find nearby users without needing to add them as friends. Our signal strength algorithm helps you estimate the distance to your lost teammates in the snow or a crowd.
·  Mesh Chat & Local Shoutbox: * Public Shoutbox: Broadcast an SOS or meeting point to everyone within a 100-meter radius.
Secure Direct Messages: Establish End-to-End Encrypted (E2EE) chats. Even if you separate, messages can "hop" through other users' devices to reach your friend.
· Offline Maps & SOS Beacons: Download high-res vector maps before you go off-grid. Share your relative coordinates with your team via offline beacons, even when GPS is unreliable.
· High-Speed File Drop: Share more than just text. Use our high-bandwidth peer-to-peer connection to drop massive GoPro videos or RAW photos in seconds, entirely off the grid.
· Absolute Privacy & Security:
Your data never leaves the local network. There are no cloud servers. All private chats are secured with state-of-the-art End-to-End Encryption, ensuring your offline communications remain strictly yours.
