LocalShare: Fast File Transfer

LocalShare is a high-performance, local-first peer-to-peer (P2P) file sharing utility designed for speed, privacy, and simplicity. Transfer photos, 4K videos, heavy documents, and entire nested folder trees directly between your devices at gigabit Wi-Fi speeds — with zero internet, zero cloud servers, and zero file size limits.

Whether you are sharing between Android phones or transferring files from Android to your Mac, Windows, Linux PC, or iPhone (via Web Portal), LocalShare bypasses slow cloud uploads and messaging compression to deliver direct local transfers protected by military-grade end-to-end encryption.

⚡ WHY CHOOSE LOCALSHARE?
━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Lightning Fast Speeds: Streams files directly over your local Wi-Fi or Wi-Fi Direct at up to 100+ MB/s (limited only by device hardware).
• 100% Private & Offline: Your files NEVER touch external servers, third-party databases, or cloud providers. Zero tracking. Zero telemetry.
• Military-Grade Encryption (E2EE): Every transfer session is authenticated and encrypted on-the-fly using X25519 key exchange and AES-256-GCM cipher.
• No File Size Restrictions: Share 50 GB movies, raw camera folders, or multi-gigabyte zip archives effortlessly.
• Resumable Streaming: Interrupted by a connection drop? LocalShare automatically resumes right from the last saved byte chunk.

🚀 POWERFUL SHARING MODES
━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Living Sonar Radar
Watch nearby devices appear on an interactive animated radar canvas. Tap any peer to start transferring instantly with ambient 6-digit PIN verification for trusted device pairing.

2. Offline Direct Hotspot (No Router Needed)
Travelling or outdoors without Wi-Fi? Create an instant private local hotspot directly inside LocalShare. Nearby peers scan the QR code to connect and transfer files at full speed with zero mobile data usage.

3. Zero-Install Web Share Portal
Need to send files to an iPhone, iPad, or PC without installing an app? Launch the Web Portal and display the generated QR code. The recipient scans it with their camera to download files directly through any web browser (Safari, Chrome, Edge).

4. Entire Folder & Directory Tree Sharing
Select entire directories and nested folder structures. LocalShare preserves folder hierarchies, sub-directories, and file paths seamlessly with built-in path-traversal sanitisation.

5. Speed Limiter & Bandwidth Throttling
Customise your bandwidth allocation with built-in speed presets (1 MB/s to 50 MB/s, or unlimited) to share smoothly without hogging your home network.
