Payment rails

Choice: The website sells unlocks through Razorpay. The Android and iOS apps sell unlocks through RevenueCat (Play Billing, App Store). CA marketplace payments stay on Razorpay everywhere. Android ships to Play as com.chitragupt.app.

Why: Google and Apple require their own billing for unlocks inside an app. The marketplace pays a third party (the CA), which store billing does not cover.

Rejected: Razorpay inside the apps (store policy) · leaving iOS out of RevenueCat.
