• Ads: IAA placement, rewarded ads, frequency, mediation, ad fatigue.
• Retention: daily check-in, streaks, missions, rewards, lifecycle messaging.
• Notifications: push permission, transactional, lifecycle, promotional, quiet hours.
• Trust: receipts, support, cancel flow, refund clarity, parental/age-sensitive UX.
