# P2P Poll App

A peer-to-peer polling application where users can create polls, add options, and vote in real-time without a central server.

## Features

- **Real-time P2P voting** using WebRTC via PeerJS
- **Dynamic option management** - add/remove options during polling
- **Duplicate vote prevention** - one vote per user
- **Automatic data synchronization** across all connected peers
- **Local storage persistence** for poll recovery
- **Responsive design** works on desktop and mobile
- **No server required** - uses PeerJS free signaling service

## How to Use

1. **Open the app** in your browser (open `index.html`)
2. **First user (Host)**: Leave the Peer ID field empty and click "Connect to Host"
3. **Copy your Peer ID** using the "Copy Your Peer ID" button
4. **Share your Peer ID** with other users (via chat, email, etc.)
5. **Other users**: Paste the host's Peer ID and click "Connect to Host"
6. **Create a poll** with question and options
7. **Vote** by clicking on options (one vote per person)
8. **Watch results** update in real-time across all devices

## Technical Details

- **P2P Library**: PeerJS (WebRTC-based)
- **Frontend**: Vanilla JavaScript with modern CSS
