Backend Design

The backend is designed with the following constraints:

• Uses flow control (if-else, for, while)
• Utilizes lists and dictionaries
• Implements the range() function
• Has multiple classes, including inheritance
• Reads and writes files
• Implements exception handling
• Uses three or more standard modules (datetime, json, logging)

Frontend Design

The frontend is built using vanilla JavaScript and interacts with the backend via RESTful API calls. It dynamically updates the UI based on user actions and data changes.

Recent Updates

• Fixed expense grouping issue to ensure expenses are correctly grouped into weeks (Monday to Sunday)
• Improved consistency between expense list, budget status, and weekly reminder date ranges

Future Improvements

• Implement user authentication
• Add data visualization for expense trends over time
• Create a mobile app version
• Integrate with financial institutions for automatic expense tracking
