ECMS Parent Engagement
Progress, early warnings and tuition notices delivered to parents by app and Zalo ZNS, with GDPR-grade controls over what is shared

Overview
Most centres communicate with parents through a group chat nobody can search, where an important message about one child scrolls past forty others. This cluster replaces that: a parent is a first-class user with a defined relationship to specific students, and they receive their child's progress, attendance, early-warning signals and tuition notices through the app and Zalo ZNS.
The privacy side is not an afterthought, because this is a system holding minors' academic records: there is consent tracking, data export, deletion, and retention policy, plus a four-layer permission model that decides exactly which fields a parent sees. Gamification - points, badges, a leaderboard - sits alongside, deliberately scoped to the student's own progress rather than public ranking.
