Terms of Use

Last updated: 2026-11-14

These Terms of Use (the “Terms”) apply when you use the app Tenth Frame for iPhone, iPad, Apple Watch and Android phones (the “App”), provided by KYWorks (“we”). By downloading and using the App, you agree to these Terms.

1. What the App does

• You record your own bowling scores by tapping the number of pins for each roll. Strikes, spares and the score are calculated for you
• You can see statistics such as your average, high score and trends
• Records on iPhone and iPad are kept in sync through iCloud. The Apple Watch app syncs through your iPhone. The Android app does not sync records between devices

2. What the App does not do

• The statistics and figures in the App are for organizing your own records. We do not promise that you will improve or any result in a tournament
• The App has no accounts, does not store your records on a server of ours, and does not share them with other users

3. Free usage and the one-time unlock

• You can enter up to 50 games for free. Once you reach the limit, you cannot enter new games. You can still view, edit and delete the games you entered and check your statistics
• Buying the one-time unlock removes the limit. It is a single payment, not a subscription, and it does not renew automatically
• The price is the amount shown in the App Store or Google Play and differs by country and region. In Japan it is ¥480 including tax
• Payment is made through the App Store (iPhone, iPad) or Google Play (Android), and the terms of Apple or Google apply to the payment
• With the same Apple account or Google account you can restore your unlock after reinstalling or changing devices, under Settings > Restore Purchases. Family Sharing is supported
• We do not give refunds. To request a refund, follow the process of Apple (for example “Report a Problem”) or Google Play. This does not apply where the law requires a refund. If a purchase is refunded, the unlock from that purchase is removed. The games you created stay in the App

4. How your records are handled

• Your records are stored on your device and, if you have turned it on, in your own iCloud (iPhone, iPad) or in your own Google account backup (Android). We cannot see or restore your records
• Records can be lost if a device is lost or broken, if the App is deleted, or because of your iCloud or backup settings. Keep your own copy of anything important
• The information we collect is described in the Privacy Policy

5. Prohibited actions

• Anything that violates the law or public order
• Analyzing the App, such as reverse engineering or decompiling it (except as permitted by law)
• Interfering with the operation of the App or of services we provide

6. Changes, suspension and end of the App

• We may change the content of the App
• We may end the App. We will announce it in the App or on the support page at least 30 days before. Copies of the App and records already on your device keep working for as long as your operating system supports them

7. No warranty

• We do not guarantee that the App is free of defects, always available, or fit for a particular purpose
• We do not guarantee that the scores and statistics calculated by the App match official records. For official tournaments and leagues, please check the record kept by the venue

8. Limit of liability

• For damage caused by our slight negligence, our liability is limited, within the range of damage that normally arises, to ¥480 or the amount you paid for the App in the 12 months up to the month the damage occurred, whichever is higher. This limit does not apply to intent or gross negligence
• Where the law (for example the Consumer Contract Act of Japan) does not allow an exclusion of liability, that exclusion in these Terms does not apply

9. Changes to these Terms

• We may change these Terms in accordance with the law
• Before a change takes effect, we will announce what changes and the date it takes effect, in the App or on the support page

10. Governing law and courts

• These Terms are governed by the laws of Japan
• Disputes about the App will be resolved in the courts that the law provides for
