Xirong Travel Tools

Xirong Travel Tools is a client-side utility application designed to assist with travel planning and expense management. Operating on the client-side, the application stores data locally and does not require sensitive device permissions.

Key Features:
1. Packing Checklist: Generate packing checklists based on 3 destination types (Beach, Mountain, City) and 3 weather scenarios (Hot, Cold, Rainy). Includes custom item entry and a progress indicator.
2. Budget Tracker: Input a total budget limit and log expenses. Supports entry in USD, EUR, GBP, JPY, CAD, and AUD with conversion to USD and remaining budget calculation. Includes visual alerts when the budget is exceeded.
3. Bill Splitter: Input group members and shared bills. The built-in algorithm calculates balances and outputs a settlement plan showing who owes whom.
4. Itinerary Planner: Create a chronological travel itinerary by inputting day, time, activity, and notes to build a vertical timeline.
5. FX Converter: Convert values between 10 currencies (USD, EUR, GBP, JPY, CAD, AUD, CHF, SGD, HKD, KRW) using pre-cached local reference rates.

Privacy & Data Handling:
- Local Storage: All checklists, budgets, and itineraries are stored on your device using browser local storage (localStorage). No data is uploaded, synchronized, or backed up to external servers.
- Permissions: The application does not request or access device location (GPS), camera, contacts, microphone, or external storage.
- Offline Use: The application runs offline once the initial page is loaded.

Disclaimer:
The currency conversion rates provided are static reference rates pre-cached within the application and do not reflect real-time market rates. Users must verify exact rates with financial institutions before conducting financial transactions.
