Preschool management system with parent app

We run a private daycare with an infant group, and everything related to the children is currently on paper: attendance log on a clipboard at the door, folder with enrollment forms, handwritten notes about sleep and meals and a board where caregivers mark who picked up whom. While there are few children this works somehow, but when a parent asks how their child slept and what they ate, we start flipping through pages. And when an inspector asks who was in the building at 10:40 AM, we can't answer confidently. We need a proper program that keeps child profiles, attendance, staff allocation, daily activities and parent billing in one place, so nothing depends on whether a busy caregiver remembers to write something down.

The foundation is a child card with contacts, list of authorized pickup people, allergies, medications, vaccination records and emergency contacts, plus quick arrival and departure marks that record exact time and the adult who brought or picked up the child. Based on these marks the program should calculate staff-to-child ratio for each group in real time and alert us as soon as a group is understaffed — this is both a safety issue and a licensing requirement. Caregivers mark sleep, meals, diaper changes, incidents and activities throughout the day, attach photos, and all this automatically builds into a daily report for each family. We also need group schedules and staff shift schedules plus monthly billing with parents: stay fees, late pickup fees and simple receipts.

The second half of the project is a mobile app for parents. Parents should see their child's daily report and photos, get notified when their child arrives and leaves, message the group, update contacts and pickup list, view schedules and pay bills from their phone. We'd like the parent app and caregiver workspace to share one backend so a caregiver note appears to the parent in seconds. We ask you to propose your tech stack, describe roles and permissions for owner, caregivers and parents and explain how you will protect children's personal data.

What must be ready:
— Child profiles with allergies, medications, emergency contacts and approved pickup list
— Arrival and departure marks with exact time and automatic staff-to-child ratio alerts
— Daily reports with sleep, meals, incidents, activities and photos for parents
— Group schedules and staff shifts plus monthly billing and receipts for parents
— Parent mobile app with notifications, messaging and online payment
