📦 What's Stored in localStorage

Each session contains:

{
  id: string,
  name: string,                    // User-provided name
  problem: string,                 // Problem description
  code: string,                    // User's code
  language: string,                // Programming language
  testCases: [],                   // Generated test cases
  chatHistory: [],                 // AI chat messages
  lastEvaluation: {},              // Last test results
  timerMinutes: number,            // Timer state
  timerStartedAt: number,          // Timer start time
  stopwatchStartedAt: number,      // Stopwatch start time
  stopwatchElapsed: number,        // Stopwatch elapsed
  createdAt: number,               // Timestamp
  updatedAt: number                // Timestamp
}

🚀 How to Use

First Time

Clone repo
npm install

Add API keys to .env.local:

GEMINI_API_KEY=your_key
JUDGE0_API_KEY=your_key
JUDGE0_API_HOST=judge0-ce.p.rapidapi.com

npm run dev
Open http://localhost:3000

Daily Workflow

Open browser → Last session auto-loads
Click ☰ to switch sessions or create new
Paste problem → Name it → Generate test cases
Write code → Toggle ☁️/🖥️ mode → Evaluate
Chat with AI in Help tab if stuck
Everything auto-saves!

🔒 Data Privacy

✅ All data stored in browser localStorage
✅ Nothing uploaded to servers except API calls
✅ .env.local gitignored (API keys safe)
✅ Works offline once loaded
✅ Each browser/device has separate data
✅ Clear browser data = lose sessions

🌐 Deployment to Vercel

Push code to GitHub (already done!)
Go to vercel.com → Import project
Add environment variables:
- GEMINI_API_KEY
- JUDGE0_API_KEY
- JUDGE0_API_HOST
Deploy!

Note: Local execution won't work on Vercel (serverless), but Cloud mode (Judge0) will work perfectly.

📝 What's NOT Uploaded to GitHub

✅ .env.local (your API keys)
✅ node_modules/ (dependencies)
✅ .next/ (build files)
✅ localStorage data (browser-only, not a file)

Your browser data is safe and private! It's stored in the browser's localStorage API, not as files.
