Parental controls or consent flow for mixed-audience apps

Mixed-audience apps — educational apps, family apps, messaging platforms rated E for Everyone — carry COPPA and GDPR Art.8 obligations for their minor users even when the app is not in the Kids category. Without parental controls, a child's account is functionally identical to an adult's: they can access the same data collection, make the same purchases, and interact with the same social features. Parental control mechanisms are also a market differentiator: parents choose apps that give them oversight, and their absence is a reason to avoid an app for family use.

For family or educational apps, add a parental PIN to gate settings, purchases, and content category changes. Integrate Screen Time API (iOS) or Digital Wellbeing API (Android) for usage limits:

import FamilyControls
import DeviceActivity
// Request Family Controls authorisation
AuthorizationCenter.shared.requestAuthorization(for: .individual) { result in
  // Handle result
}

Consider implementing a distinct 'child profile' vs. 'parent account' model — store isChildProfile: boolean server-side and use it to gate data collection, social features, and purchasing flows. Apple's 'Sign in with Apple' family sharing features can bootstrap this for iOS-first apps.
