How do I subscribe, cancel, or restore a purchase?

Subscriptions are handled through App Store in-app purchase — plans and prices are shown in the app. Payment is processed by Apple; we never see your payment details.

• Cancel: manage it in your device's Settings → Apple Account → Subscriptions. Cancel at least 24 hours before the current period ends to avoid renewal.
• Restore: after switching devices or reinstalling, tap "Restore Purchase" on DingPOS's subscription page.
• Change plans: pick the new plan on DingPOS's subscription page. Upgrades (Standard to Pro, monthly to annual) take effect immediately, with Apple prorating the difference; downgrades take effect at renewal.
