Part 6 — Data Privacy

Summary of Changes

• Firebase Service (lib/services/firebase_service.dart):
  • Added TODO comments to various methods to indicate where backend implementation for data privacy and access control is required. These comments serve as a guide for future Firebase integration to ensure:
    • Global uniqueness checking for usernames (signUpWithEmail).
    • Secure storage of parent-child relationships and proper access control for user profiles (createUserProfile, getUserProfile).
    • Correct association of kidID and parentID for tasks and enforcement of access control for task creation, updates, and deletions (createTask, updateTask, deleteTask).
    • Filtering of tasks by kidID and parentID for respective streams (getTasksStream, getParentTasksStream).
    • Verification of taskId ownership and parent-child linkage for proof uploads, task approvals, and rejections (uploadTaskProof, approveTask, rejectTask).
    • Secure establishment and breaking of parent-child links (linkChildToParent, unlinkChildFromParent).
    • Controlled access to child usernames and parent's children lists (getChildIdByUsername, getParentChildrenStream).

Next Steps

• Implement the stubbed methods in lib/services/firebase_service.dart with actual Firebase functionality, paying close attention to the TODO comments regarding data privacy and access control. This will involve setting up Firestore security rules and implementing server-side logic to enforce these privacy requirements.
