Terms of Use
Hyoyomi / Established November 15, 2026 / Last updated November 15, 2026
These terms govern your use of the iPhone app “Hyoyomi” (the “App”) provided by Ryo Tsuzukihashi (independent developer / TsuzuKit, the “Developer”). By using the App, you agree to these terms.
Article 1 (Scope)
These terms apply to everyone who uses the App (“Users”). The App is distributed through the App Store, and Apple's Standard License Agreement (EULA) also applies. If these terms and the EULA conflict, these terms prevail.
Article 2 (About the App)
- The App is for practicing the numerical section (chart reading, reverse arithmetic, table blanks) of web aptitude tests used in Japanese job hunting
- The App is not affiliated with the test provider (SHL-Japan Limited) and is not official material
- Questions and explanations were generated by the Developer by calculation from chart data for this App. They are not actual test questions. All figures in the charts are fictional, for practice only. Questions are in Japanese
- There is no account sign-up or login. The App is for iPhone only
Article 3 (Price)
- The App is a paid app purchased once on the App Store. The price shown on the App Store is authoritative
- There are no in-app purchases, subscriptions, or ads. No additional payment is ever requested after purchase
- With the same Apple Account, you can download the App again on a new device or after reinstalling without paying again
- Refunds follow Apple's policy. Please request one through Apple Support (reportaproblem.apple.com). The Developer can't issue refunds directly
Article 4 (Accuracy and test targets)
- The Developer checks every answer and explanation by re-solving all questions with separate code and by having them re-solved by another reviewer. Mistakes may still remain
- If you find a mistake, please report it from “Report a Problem with This Question” in the App. It will be checked and fixed in an update
- The numbers of questions, time limits, and per-question targets shown in the App are commonly known guidelines. Actual tests can vary by company and test format
Article 5 (Prohibited conduct)
When using the App, you must not:
- Violate laws or public order and morals
- Copy, republish, distribute, or sell the App's questions or explanations without the Developer's permission
- Decompile, analyze, or modify the App
- Obtain or distribute the App by any means other than official channels
- Do anything else the Developer deems inappropriate
Article 6 (Intellectual property)
Rights to the App's questions, explanations, screens, artwork, and name belong to the Developer. “Tamatebako”, “GAB”, and “C-GAB” are names of tests provided by SHL-Japan Limited and are used in the App only to help you choose which test you're preparing for.
Article 7 (Data)
Study records are stored on your device and in your own iCloud; the Developer holds no copy. If they are lost through device failure or loss, deleting the App, iCloud settings, or similar, the Developer can't restore them.
Article 8 (Disclaimer)
- The App is provided as is. The Developer does not guarantee that it is free of errors, always available, or fit for any particular purpose
- The App does not promise any test result or hiring outcome. Targets are not numbers that guarantee passing
- Except in cases of the Developer's intent or gross negligence, the Developer is not liable for damages arising from using or being unable to use the App. Where liable, liability is limited to the amount you paid for the App
Article 9 (Changes and termination)
The Developer may change the App or end its provision. When these terms change, this page will be updated along with the date above.
Article 10 (Governing law and jurisdiction)
These terms are governed by the laws of Japan. The court with jurisdiction over the Developer's address has exclusive agreed jurisdiction in the first instance over disputes concerning the App.
