Terms of Use

Last updated: July 4, 2026 / Effective: July 4, 2026

These Terms of Use ("Terms") govern your use of the Inbasket iOS application (the "App"), which is provided by its developer ("Developer", "we", or "us"). By downloading, installing, or using the App, you (the "User") agree to be bound by these Terms.

These Terms are the English translation of the original Japanese version. In the event of any inconsistency between the Japanese and English versions, the Japanese version shall prevail.

1. Scope

These Terms set out the conditions for the provision of the App and the rights and obligations between you and the Developer concerning your use of the App.
Any guidelines, notices, or supplementary terms posted by the Developer within the App or on related websites form part of these Terms.
If there is any conflict between these Terms and such guidelines, these Terms will prevail unless expressly stated otherwise.
The App is distributed via Apple Inc.'s ("Apple") App Store, and your use of the App is also subject to Apple's "Apple Media Services Terms and Conditions" ("Apple Terms"). In the event of any conflict between these Terms and the Apple Terms, the Apple Terms will prevail with respect to the matters covered therein.

2. The App

The App is a training tool that helps you practice "in-basket" exercises used in promotion examinations and other assessments. The specific functionality, specifications, and form of the App may be determined and modified by the Developer from time to time.
Some or all features of the App may vary depending on the App version, operating system version, region, and other factors.
The App does not guarantee that you will pass any examination, assessment, or other evaluation, reach any passing threshold, or achieve any particular rating, promotion, or other outcome. The effect of using the App varies between individuals, and actual results depend on your knowledge, experience, and preparation, the grading criteria of the administering organization, and other factors outside our control.

3. Use of Content

The exercises, cases, organizational charts, model answers, explanations, and all other materials provided in the App ("Content") are works owned by the Developer or its rights holders and may be used only for your personal study.
All persons, organizations, entities, place names, and other elements appearing in the Content are entirely fictional and bear no relation to any real person, organization, or entity.
You must not do any of the following with respect to the Content:
1. take screenshots, screen recordings, or photographs, or otherwise reproduce, copy, or print it;
2. redistribute, transmit, lend, or transfer it to any third party;
3. post, upload, or otherwise share it on social media or any other internet service;
4. use it beyond your personal study, or for any commercial purpose.
If the Developer becomes aware of conduct that violates the preceding paragraph, the Developer may suspend your use of the App and take other measures, including legal action.
To protect the Content for the purposes described above, the App may detect when you take a screenshot or start a screen recording on your device, display a warning, or record the fact that such an event occurred. See the Privacy Policy for details.

4. Registration

The App can be used without account registration or sign-in. Answers, notes, study history, and other data you enter into the App are stored only on your device and are not transmitted to any server operated by us. You acknowledge that such data may be lost if your device is lost, reset, replaced, or if you delete the App.

5. Fees (Subscription)

The core features of the App are available free of charge. You are responsible for any data, device, and other costs associated with your use of the App.
The App offers an auto-renewable monthly subscription, "Inbasket Premium" (the "Paid Plan"). The price shown on the purchase screen applies and is charged through your Apple ID. Any purchase you make is subject to the Apple Terms and the App Store's purchase processes.
The Paid Plan renews automatically and the fee is charged at renewal unless you cancel at least 24 hours before the end of the current period.
You can cancel at any time from Settings → Apple ID → Subscriptions on your device. After cancellation, you keep access to the Paid Plan features until the end of the period you have already paid for. No prorated refunds are provided. We cannot directly stop auto-renewal or issue refunds; refunds are subject to Apple's discretion and procedures.

6. License

Subject to these Terms, the Developer grants you a non-exclusive, non-transferable, revocable license to use the App on iOS devices for your personal, non-commercial purposes.
All intellectual property rights in and to the App, including the Content, belong to the Developer or its respective rights holders. Except as expressly set forth in these Terms, no rights to the App or the Content are transferred to you.
You shall not reverse engineer, decompile, disassemble, modify, create derivative works of, redistribute, rent, lease, sublicense, or transfer the App or any part of it, except to the extent such restrictions are prohibited by applicable law.

7. User Content

All rights, including copyright, in the answers, notes, and other content you create in the App ("User Content") remain with you.
User Content is stored only on your device, and the Developer does not review its substance. The Developer is not responsible for User Content.

8. Prohibited Conduct

You agree not to:

violate any applicable law, regulation, or public order and morals;
engage in conduct related to criminal activity;
violate the terms of use of the Content set out in Section 3;
infringe the intellectual property rights, portrait rights, privacy, honor, or other rights or interests of the Developer, other users, or third parties;
interfere with the operation of the App, impose excessive load, or probe or exploit security vulnerabilities;
unlawfully obtain, analyze, or use the App's source code, APIs, or communications;
damage or interfere with any server or network related to the App, attempt unauthorized access, or execute malicious scripts or programs;
manipulate the App's contents, reviews, ratings, or rankings by unfair means;
use the App for any commercial purpose without our prior written consent;
engage in any other conduct that the Developer reasonably deems inappropriate.

9. Suspension, Modification, and Discontinuation

The Developer may suspend or interrupt the provision of all or part of the App, without prior notice to you, in any of the following situations:
1. maintenance, updates, inspection, or repair of the App;
2. earthquakes, lightning, fire, power outages, natural disasters, war, terrorism, epidemics, or other events of force majeure;
3. failure of computers or communication lines due to accidents;
4. other circumstances under which the Developer reasonably determines that providing the App is impracticable.
The Developer is not liable for any disadvantage or damage incurred by you or any third party as a result of such suspension or interruption, except in cases of willful misconduct or gross negligence by the Developer.
The Developer may modify the contents of the App without prior notice to you.
The Developer may discontinue the App with reasonable prior notice (typically 30 days). Where unavoidable circumstances exist, this notice period may be shortened.

10. Use Restrictions

The Developer may, without prior notice, restrict your use of all or part of the App or block your access to any server related to the App if:

you violate any provision of these Terms;
the Developer reasonably determines that your conduct is likely to cause harm to the Developer, other users, or third parties;
the Developer otherwise reasonably determines that your use of the App is inappropriate.

11. Disclaimers and Limitation of Liability

The App is provided on an "as is" and "as available" basis. To the maximum extent permitted by applicable law, the Developer disclaims all warranties of any kind, whether express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, accuracy, completeness, reliability, security, non-infringement, and absence of errors or bugs.
The Developer does not warrant, expressly or implicitly, that use of the App will result in you passing any examination or other assessment, or achieving any particular rating, promotion, or other outcome. Examination results depend on the grading criteria of the administering organization and other factors, and the Content is provided solely as study and practice material.
All persons, organizations, and entities appearing in the App's Content are fictional, and the Developer does not intend to evaluate, imply, or satirize any real person, organization, or entity.
To the maximum extent permitted by applicable law, the Developer will not be liable to you for any damages arising out of or in connection with your use of or inability to use the App, except in the following cases:
1. damages arising from the Developer's willful misconduct or gross negligence;
2. cases in which liability cannot be excluded under applicable mandatory law.
Even in cases where the Developer is liable under the preceding paragraph, the Developer's liability is limited to direct and actual damages ordinarily arising, and the aggregate amount of liability shall not exceed the total amount you paid directly to the Developer for the App in the 12 months preceding the event giving rise to the liability (or zero, if no such amount was paid). Nothing in this paragraph limits liability for willful misconduct, gross negligence, or any other liability that cannot be limited under applicable law (including, where applicable, the Japanese Consumer Contract Act).
The Developer is not liable for any transactions, communications, or disputes between you and any other user or third party in connection with the App.

12. Third-Party Services

The App uses third-party services such as Firebase, provided by Google LLC, for analytics, RevenueCat for subscription management, and Apple's SKAdNetwork framework for advertising measurement (see the Privacy Policy for details). Your use of such services is subject to the respective providers' terms and privacy policies.
The App may contain links to third-party websites or services (including our support form). The Developer is not responsible for the content of such third-party sites or services.

13. Privacy

Information collected in connection with your use of the App is handled in accordance with our separate Privacy Policy. By agreeing to these Terms, you also agree to the Privacy Policy.

14. Changes to These Terms

On the premise that these Terms constitute a standard-form contract (teikei yakkan) under the Japanese Civil Code, the Developer may amend these Terms without obtaining your individual consent, in accordance with Article 548-4 of the Civil Code, where:
1. the amendment conforms to the general interests of users; or
2. the amendment does not contradict the purpose for which the App is provided and is reasonable in light of the necessity for the amendment, the appropriateness of its content, and other relevant circumstances.
For any amendment other than one that conforms to the general interests of users, the Developer will set an effective date and, before that date arrives, will notify users of the fact of the amendment, its content, and its effective date through in-app notices, postings on the website, or other appropriate means. An amendment that conforms to the general interests of users takes effect when posted on this page.
If you continue to use the App after the amended Terms take effect, you are deemed to have agreed to the amended Terms.

15. Contact

All inquiries and communications regarding the App should be sent to:

Email: sk.createapp@gmail.com
Support Form: Google Form

16. Governing Law and Jurisdiction

These Terms are governed by the laws of Japan, without regard to its conflict of laws principles.
Any dispute arising out of or in connection with the App or these Terms shall be subject to the exclusive jurisdiction of the Tokyo Summary Court or the Tokyo District Court as the court of first instance, depending on the amount in controversy. The foregoing does not affect any non-waivable rights of consumers under applicable law to bring an action in their place of residence.

17. Apple End User License Provisions

Because the App is distributed via Apple's App Store, the following additional terms apply:

These Terms are concluded between you and the Developer only, and not with Apple. The Developer, not Apple, is solely responsible for the App and its contents.
These Terms apply to the extent they are not inconsistent with Apple's applicable terms for the App Store. To the extent of any conflict, Apple's applicable terms will prevail.
Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the App.
Apple is not responsible for addressing any claims by you or any third party relating to the App or your possession or use of the App, including but not limited to (i) product liability claims, (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement, and (iii) claims arising under consumer protection, privacy, or similar legislation.
In the event of any third-party claim that the App or your possession or use of the App infringes that third party's intellectual property rights, the Developer, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such intellectual property infringement claim.
Apple and its subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple has the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

18. Severability

If any provision of these Terms or any part of any provision is held to be invalid or unenforceable under applicable law (including the Japanese Consumer Contract Act), the remaining provisions and remaining parts of the affected provision shall continue in full force and effect.

These Terms are provided by the Developer for general informational purposes and are not a substitute for individualized legal advice.
