Terms of Use
Chessby is licensed to you under Apple’s Standard Licensed Application End User License Agreement (EULA). By downloading or using the app you agree to that agreement. The points below summarise how Chessby Pro subscriptions work and do not replace it.
Chessby Pro subscriptions
- Chessby is free to download. Chessby Pro is an optional auto-renewable subscription, offered monthly and yearly. Prices are shown in the app before you buy and may vary by country.
- The yearly plan may include a free trial for new subscribers. If you do not cancel at least 24 hours before the trial ends, the subscription starts and you are charged.
- Payment is charged to your Apple Account when you confirm the purchase (or when the trial ends).
- The subscription renews automatically at the same price and period unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
- You can manage or cancel your subscription in iOS Settings › your name › Subscriptions, or from the Chessby Pro row in the app's Settings. Cancelling stops the next renewal; Pro stays on until the end of the period you paid for.
- Refunds are handled by Apple: reportaproblem.apple.com.
- Bought on another device or reinstalled? Use Restore on the Chessby Pro screen.
