Kaomi works primarily offline. The App only connects to the internet for:
1. In-App Purchases — when you buy Kaomi Pro, the request is processed through Apple's StoreKit. The developer does not see or store your payment details.
2. Restore Purchases — when you tap "Restore Purchase", the App contacts the App Store to verify your previous purchase.
All payment processing is handled by Apple. The developer never receives your credit card information, Apple ID password, or any personal payment details.
