5. WhatsApp Integration: Recipient phone numbers are used only to launch the WhatsApp application with pre-filled celebratory messages at your request. 

6. Cloud Storage: Friend records, authentication tokens, and uploaded profile photos are securely hosted on Google Firebase (Authentication, Firestore, and Cloud Storage) for cross-device synchronization. 

7. On-Device Storage: Your registration details, Google authentication state, and group preferences are stored locally on your device to ensure a seamless and responsive experience. 

8. Data Control: Administrators have full authority to add, modify, or delete records, while users can update their registered number to refresh group access.
