# Copynsync

> Local network clipboard sync and file transfer application for Android, macOS, and Windows.

Copynsync is a background-first utility that allows you to sync your clipboard, files, and folders between devices on your local network. It avoids cloud relays by using direct device-to-device TLS-secured connections.

## Key Features

- **Clipboard Sync**: Copy on one device, paste on the other. Runs quietly in the background once paired.
- **File & Folder Transfer**: Send files or full folders directly between trusted devices at speeds up to 50 Mbps.
- **Local Network Only**: Data stays on your own network. No cloud storage or third-party servers.
- **Secured Connections**: Direct transfers are encrypted using TLS.
- **Trusted Device Pairing**: Simple discovery and pairing with matching approval codes and QR linking.
- **Transfer History**: Keep track of what was sent and received across all your devices.

## Technical Details

- **Platforms**: Android, macOS, Windows (iOS and Linux coming soon).
- **Communication**: Local network (WiFi/LAN) using device-to-device discovery.
- **Security**: TLS-secured communication between paired trusted devices.
- **Cloud-Free**: Zero cloud relay; your data never leaves your network.
