💳 EMI & Expense Tracker🔒 SEALED

⏱️ What Happens When You Seal:

1. 3-second countdown - Last chance to press STOP
2. 5-second undo period - Final window to press UNDO
3. Total: 8 seconds of deliberation

🔒 During These 8 Seconds:

• ❌ Cannot edit items
• ❌ Cannot check/uncheck payments
• ❌ Cannot delete items
• ❌ Cannot add new items

✅ After Sealing:

• 🔒 All payments locked until next month
• 🛡️ Protected from accidental touches
• 🧘 Financial peace of mind achieved
• 📅 Auto-unlocks on the 1st of next month

🚨 Critical Rules:

• ❌ Never open in text editor - Don't modify the JSON file
• ❌ Never change file extension - Keep it as .json
• ❌ Never rename incorrectly - Original name is best
• ❌ Edited/corrupted files WILL FAIL import - You'll lose data!

✅ What You SHOULD Do:

• Download and store safely - Don't touch the file contents
• Email to yourself - Multiple copies = safer
• Upload to cloud storage - Google Drive, Dropbox, etc.
• Keep multiple backups - Export monthly for safety

🚨 Risk of Data Loss:

• ❌ Clearing browser cache/data will delete everything
• ❌ Browser updates may reset local storage
• ❌ Using incognito/private mode won't save data
• ❌ Switching devices means starting fresh
• ❌ Uninstalling the app removes all records

✅ How to Protect Your Data:

• 💾 Export regularly - Click "📤 Export" to save a backup
• 📧 Email the backup file to yourself
• ☁️ Store it in cloud storage (Google Drive, Dropbox, etc.)
• 📱 Keep backups on multiple devices
• 🔄 Make it a monthly habit after sealing payments

🚫 Critical: DO NOT Edit the Backup File!

⚠️ Never modify the exported JSON file at any cost! Even a single character change will corrupt it and make import fail. The file works perfectly as-is - store it safely without opening or editing it.

🔒 Privacy by Design:

• ✅ No servers - your data never leaves your device
• ✅ No cloud sync - complete privacy control
• ✅ No accounts - no sign-up required
• ✅ 100% offline - works without internet FOREVER

⚠️ Important Implications:

• ❌ No automatic sync across devices - Use Export/Import
• ❌ No server-side validation - You're responsible for accuracy
• ❌ No automatic backups - Export regularly yourself
• ❌ No data recovery - If deleted, it's gone forever

✅ Your Responsibility:

• Verify your entries - Double-check amounts and dates every month
• Export regularly - Keep backups safe
• Reconcile manually - Cross-check with bank statements
• Accept the trade-off - Privacy means self-management

📦 Import Summary:

ℹ️ What Will Happen:

• Data will be added - Merges with your existing data
• No data loss - Your current items remain untouched
• Duplicates possible - Check for duplicate entries after import

📋 Common Causes:

• ❌ File was downloaded incompletely
• ❌ Manually edited in text editor
• ❌ Wrong file selected (not from this app)
• ❌ File corrupted during transfer

✅ What to Do:

• Try a different backup file - Use an older backup
• Export fresh backup - From a working device
• Check file size - Should be at least 100 bytes
• Don't manually edit - JSON files are fragile
