Expenseek gives you the best of both worlds: powerful cloud-based collaboration when you need it, and private offline tracking when you don't. Choose the mode that fits your situation perfectly.

Two Modes, Complete Flexibility

Online Groups (Cloud-Synced)

How It Works Online groups leverage cloud technology (Firebase) to sync data across all members' devices in real-time. When anyone adds an expense, everyone sees it instantly.

Perfect For:

  • 👨‍👩‍👧‍👦 Family Expenses - Everyone stays updated
  • 🏠 Roommate Bills - Real-time transparency
  • ✈️ Group Travel - Collaborative trip tracking
  • 💼 Team Projects - Shared work expenses
  • 🎉 Event Planning - Multiple organizers adding costs

Key Benefits:

  • ⚡ Real-time synchronization
  • 📱 Access from any device
  • 🔄 Automatic backups
  • 👥 Unlimited members
  • 🌍 Access anywhere with internet

Technical Features:

  • Encrypted data transmission
  • Secure authentication
  • Cross-platform compatibility (iOS, Android, Web)
  • Automatic conflict resolution
  • Version history tracking

Offline Groups (Local Storage)

How It Works Offline groups store data exclusively on your device. No cloud sync, no internet required, no one else can access it.

Perfect For:

  • 📝 Personal Tracking - Your eyes only
  • 🎁 Gift Planning - Surprise expense tracking
  • 💰 Loan Tracking - Private debt records
  • 🏦 Budget Planning - Solo expense analysis
  • 🔒 Sensitive Finances - Maximum privacy

Key Benefits:

  • 🔐 Complete privacy
  • 📶 Works without internet
  • ⚡ Lightning fast
  • 💾 Device-only storage
  • 🎯 Distraction-free

Technical Features:

  • Encrypted local storage
  • Export/backup capabilities
  • Device-specific data
  • No account required
  • Zero server communication

Choosing the Right Mode

Use Online Groups When:

✅ Multiple people need access simultaneously
✅ You want automatic backups in the cloud
✅ Members are in different locations
✅ Real-time updates are important
✅ You need multi-device access

Example Scenarios:

  • "Our household of 4 roommates needs to track utilities, groceries, and rent. We all need to see expenses as they're added."
  • "I'm planning a destination wedding with 3 co-organizers in different cities. We need to collaborate on venue costs, catering, and decorations."

Use Offline Groups When:

✅ Only you need access to the data
✅ Privacy is paramount
✅ Internet connectivity is unreliable
✅ You're tracking something temporary
✅ You don't want cloud storage

Example Scenarios:

  • "I'm planning a surprise birthday party and don't want my partner to see the expenses."
  • "I'm tracking money I lent to friends, but I don't want to share the full list with everyone."

Can You Switch Modes?

Current Limitations:

  • Groups cannot be converted between modes
  • Each mode uses different storage mechanisms
  • Data doesn't automatically transfer

Workaround: You can manually recreate a group in the other mode, or export data from offline and import to online (future feature planned).

Best Practice: Choose the right mode when creating the group. Ask yourself: "Do others need access to this data?"

Security & Privacy

Online Groups:

  • End-to-end encrypted data transmission

  • 🔄 Import to new device manually

Performance Optimization

Online Groups:

  • Smart caching reduces data usage
  • Background sync when app is closed
  • Conflict resolution for simultaneous edits
  • Pagination for large histories
  • Lazy loading for better performance

Best Practices

For Online Groups:

  1. Regular Settlements - Keep balances manageable
  2. Clear Naming - "Smith Family 2026" not just "Family"
  3. Remove Inactive Members - Keep groups lean
  4. Set Group Currency - Reduces confusion
  5. Use Categories - Makes analytics more useful

For Offline Groups:

  1. Regular Exports - Backup your data manually
  2. Descriptive Notes - You're the only one who'll read them
  3. Clean Up Old Data - Delete settled/irrelevant groups
  4. Use Device Backup - Include Expenseek in phone backups
  5. Multi-Device? - Consider using online mode instead

Use Both Modes!

You can create both online and offline groups simultaneously:

Example Multi-Mode Strategy:

  • Online: "Apartment 4B" (roommates)
  • Online: "Europe Trip 2026" (travel group)
  • Offline: "Gift Shopping Tracker" (surprise party)
  • Offline: "Personal Loans" (private records)

Switch between modes seamlessly in the app. The home screen shows all groups organized by type.

Coming Soon

We're constantly improving! Planned features:

  • 📤 Batch import/export
  • 🔗 Selective sharing (offline → temporary link)

Getting Started

Create Your First Groups:

  1. Download Expenseek (free on iOS & Android)
  2. Choose "Create Online Group" or "Create Offline Group"
  3. Follow the simple setup wizard
  4. Start tracking expenses immediately!

Not sure which mode to choose? Start with online - it's more versatile and you can always create offline groups later for private tracking.

Questions?

Q: Can I have members in an offline group? A: No, offline groups are solo-only. Use online groups for collaboration.

Q: What if I lose internet in an online group? A: Cached data remains accessible offline. Changes sync when you reconnect.

Q: Which mode is more secure? A: Both are secure! Offline is more private (device-only), online is more resistant to device loss (cloud backup).

Q: Can I export data from online groups? A: Yes! All groups support PDF and CSV exports regardless of mode.
