6. Data Flow and Integration Points

6.1. User Registration and Authentication

	•	Flow:
	1.	User registers or logs in via the AuthenticationModule.
	2.	Upon successful authentication, the UserDataStorageModule retrieves the user’s profile and preferences.

6.2. Chat Functionality

	•	Flow:
	1.	User inputs a message via the ChatInterfaceModule.
	2.	Message is saved using the UserDataStorageModule.
	3.	AIIntegrationModule sends the message and relevant context to the GPT-4o API.
	4.	The response is received and displayed using the ChatInterfaceModule.
	5.	ConversationHistory is updated accordingly.
	•	Note: If data categorization is required, refer to the Data Categorization Document.

6.3. Proactive Messaging and Notifications

	•	Flow:
	1.	Based on user data and scheduled events, the NotificationModule schedules notifications.
	2.	Notifications trigger the app to send proactive messages via the ChatInterfaceModule.
	•	Note: For data-driven notifications, see the Data Categorization Document.

6.4. Module Marketplace

	•	Flow:
	1.	User browses modules using the ModuleMarketplaceModule.
	2.	Purchases are processed, and the UserDataStorageModule updates the user’s purchased modules.
	3.	Purchased modules influence AI responses via the AIIntegrationModule.

7. Additional Considerations

7.1. API Key Management

	•	Security: API keys for services like OpenAI should be stored securely and not hard-coded into the app.
	•	Best Practice: Use a secure backend server to manage API requests if possible.

7.2. Error Handling

	•	Implement comprehensive error handling and user feedback mechanisms across all modules.

7.3. Accessibility

	•	Ensure that the app complies with accessibility standards for all users.

7.4. Internationalization

	•	Plan for supporting multiple languages if targeting a global audience.

8. How to Use This Document

	•	For Modules Not Requiring Data Categorization:
	•	Use this document as is for development.
	•	For Modules Requiring Data Categorization:
	•	Refer to the separate Data Categorization Document for detailed data structures, APIs, and implementation guidelines.
