Questions & Answers

As answered by people managing CheckIO and RefundShield.

What's the story behind your product?

RefundShield's answer:

We built RefundShield to help app developers protect their revenue from refund abuse and friendly fraud on the App Store.

If you run an iOS or macOS app with in-app purchases or subscriptions, refunds can quietly eat into your revenue and, in many cases, teams don’t have enough visibility into what’s happening, which users are repeatedly refunding, or how much money is being lost.

RefundShield connects with Apple’s refund data and helps you:

  • Detect suspicious refund behavior
  • Track refund patterns across users and transactions
  • Protect subscription and in-app purchase revenue
  • Get clearer insights into refund-related losses
  • Take action before refund abuse becomes a bigger problem

Are you a mobile app developer for Apple App Store? We’d love your feedback!

What makes your product unique?

RefundShield's answer:

RefundShield automatically blocks unjustified refunds and protects App Store developers revenue. No SDKs require, setup in minutes.

How would you describe the primary audience of your product?

RefundShield's answer:
