## 💡 What Is It?

## ⚙️ Configuration

**Set max session time:**

**Edit** `src/config.jsonc`:
```jsonc
{
  "buyMode": {
    "maxMinutes": 45  // Session duration (minimum: 10, default: 45)
  }
}
```

**Session behavior:**
- Monitor tab refreshes every ~10 seconds
- Session automatically ends after `maxMinutes`
- You can close the browser anytime
- Cookies are saved at the end

---

## 🔔 Notifications

Buy mode sends real-time alerts when:
- 💳 **Points spent** — Shows amount and new balance
- 📉 **Balance changes** — Tracks cumulative spending

**Example alert:**
```
💳 Spend Detected (Buy Mode)
Account: user@email.com
Spent: -500 points
Current: 12,500 points
Session spent: 1,200 points
```

**Alert channels:** Uses your configured webhooks (Discord, NTFY, etc.)

---

## 🛠️ Troubleshooting

| Problem | Solution |
|---------|----------|
| **"No enabled accounts found"** | Enable at least one account in `accounts.jsonc` |
| **"Invalid account index"** | Check your account number (must be 1-N) |
| **"Account not found"** | Verify email spelling and that account is enabled |
| **Monitor tab closes** | Script auto-reopens it in background |
| **No spending alerts** | Check webhook/NTFY config in `config.jsonc` |
| **Session too short** | Increase `maxMinutes` in config |
| **Interactive prompt not showing** | Run: `npm run buy` (no arguments) |

---

## ⚠️ Important Notes

- ✅ **Browser visible** — Always runs in visible mode (not headless)
- ✅ **No automation** — Script only monitors, never clicks or redeems
- ✅ **Safe** — Use your browsing tab normally
- ✅ **Real-time tracking** — Immediate notifications on point changes
- ✅ **Multiple selection methods** — Interactive, email, or index
- ✅ **Privacy-friendly** — Emails are masked in interactive mode
- ⚠️ **Only enabled accounts** — Disabled accounts don't appear

---

## 📊 Session Summary

At the end of each buy mode session, you'll receive a summary:

```
Account: myaccount@outlook.com
Duration: 45m 12s
Initial points: 15,000
Current points: 13,500
Total spent: 1,500
```

This summary is sent via your configured notification channels.
