Terms of Use

These Terms of Use ("Terms") govern your use of the mobile application "English Writing Routine" (英作文リマインダー) (the "App"), provided by Valley Innovation Inc. ("we", "us", or "our"). By using the App, you agree to these Terms.

This English text is provided for convenience. If there is any discrepancy between this text and the Japanese version, the Japanese version prevails.

1. Scope

1. These Terms apply to all matters between you and us relating to your use of the App.
2. The terms of the platform that distributes the App also apply, including the Apple Media Services Terms and Conditions (Apple Inc.) and the Google Play Terms of Service (Google LLC).

2. Identifying users

1. No name, email address, or password is required to use the App. On first launch, the App creates an anonymous user identifier, which is used to enforce the daily scoring limit and to determine whether a Premium subscription is active.
2. That identifier is stored on your device. If you delete the App or change devices, the learning history stored on the device is not carried over. The identifier itself may, depending on the behaviour of the storage provided by the operating system, survive deletion of the App and be carried over if you reinstall on the same device (see Section 7 of the Privacy Policy).
3. Premium purchases are tied to your App Store or Google Play account, so you can restore them on another device using "Restore purchases" with the same store account.

3. Minors

1. If you are a minor, please use the App with the consent of your parent or legal guardian.
2. Obtain that consent before purchasing Premium or making any other payment. A contract entered into by a minor without the consent of their legal guardian may be rescinded under the Civil Code of Japan or other applicable law. The practical procedure for rescission or refund follows applicable law and the rules of the App Store or Google Play.
3. The App is not directed at children under 13. If a child under 13 uses the App, they should do so with the consent and supervision of a parent or legal guardian.

4. AI-generated scoring

1. The score, strengths, suggested improvements, and model answers returned by the App (together, the "Results") are generated automatically by a generative AI system (a large language model).
2. The Results are provided as a learning aid. We do not warrant their accuracy, appropriateness, or usefulness, nor that they match the marking criteria of any particular examination or qualification.
3. If you rely on the Results for exam preparation, professional writing, or any other purpose, you are responsible for verifying the content yourself.
4. The App scores answers written in response to a prompt. If you submit content unrelated to the prompt, the App may return no Results. This still consumes one of your daily scoring attempts under Section 5.5.

5. Fees and Premium

The App is free to use. We also offer a paid plan ("Premium") that increases the number of scoring attempts available each day.

1. Premium is an auto-renewing subscription. Unless it is cancelled at least 24 hours before the end of the current period, it renews automatically, and your store account is charged for the renewal within the 24 hours before the period ends.
2. To cancel, use the subscription management screen of the App Store or Google Play. You can open that screen from the App's settings. Deleting the App from your device does not cancel the subscription.
3. If you cancel, Premium remains available until the end of the period you have already paid for. We do not refund the unused portion of a period that has been cancelled part-way through.
4. Payment, billing, and refunds are handled by Apple or Google. To request a refund, follow the procedure of the relevant store. We cannot issue refunds directly.
5. The daily limit is 3 scoring attempts on the free plan and 20 on Premium. The count resets every day at 00:00 Coordinated Universal Time (UTC), which is 09:00 Japan Standard Time.
6. Prices and the contents of Premium may change. If we make a change that is disadvantageous to you, such as a price increase, we will announce it in advance in the App or on this website.

6. Prohibited conduct

You must not:

• violate any law or public order and morals;
• infringe the intellectual property, privacy, reputation, or other rights of us or any third party;
• damage or interfere with the servers or network used by the App;
• attempt unauthorised access, reverse engineering, or sending large volumes of automated requests;
• circumvent the daily limit on scoring attempts;
• enter or transmit the personal information or confidential information of any third party;
• enter content that is unlawful, harmful, or otherwise inappropriate to send to a generative AI system; or
• engage in any other conduct that we reasonably consider inappropriate.

7. Intellectual property

1. Copyright and other intellectual property rights in the App and its content, including the writing prompts, belong to us or to the rightful owners.
2. You retain copyright in the compositions you write. We use them only to the extent necessary to provide the scoring service (see the Privacy Policy for details).
3. You may freely use the Results for your own learning.

8. Restriction and suspension of use

We may restrict or suspend your use of the App without prior notice if you breach these Terms or if we consider it necessary for the operation of the App.

9. Changes, interruption, and discontinuation

1. We may change the App or temporarily interrupt it without prior notice.
2. If we discontinue the App, we will give advance notice where reasonably possible. If we discontinue Premium, any remaining paid period will be handled in accordance with the rules of the relevant store.

10. Disclaimers

1. We do not warrant that the App is fit for your particular purpose, that it will produce any expected learning outcome, or that it will be available without interruption.
2. We are not liable where the App cannot be used because of your network conditions, your device, or a failure of an external service (the distribution platform, the AI provider, the cloud provider, and the like).
3. We are not liable for the loss of learning history stored on your device. Please make your own backups if you need them.

11. Limitation of liability

1. Where we are liable for damage caused to you by our fault, our liability is limited to the total amount you paid us in relation to the App during the 12 months preceding the occurrence of the damage.
2. We are not liable for lost profits or for any indirect or special damage.
3. Sections 11.1 and 11.2 do not apply where we have acted with intent or gross negligence, or to the extent that a limitation of liability is not permitted under the Consumer Contract Act of Japan or other applicable law.

12. Indemnity

If a dispute arises with a third party because you breached these Terms or used the App inappropriately, you are responsible for resolving it at your own cost. If we suffer loss in connection with such a dispute (including reasonable legal fees), you shall compensate us for it. This does not apply where the loss is attributable to our fault.

13. Assignment

1. You may not assign or pledge your position under these Terms, or any right or obligation arising from them, without our prior written consent.
2. If we transfer the business relating to the App to a third party (including by merger or other general succession), we may transfer to the transferee our position under these Terms, the rights and obligations arising from them, and users' information.

14. Changes to these Terms

We may amend these Terms where we consider it necessary. Amended Terms take effect when published on this website. We will announce changes that materially affect you in the App.

15. Governing law and jurisdiction

1. These Terms are governed by and construed in accordance with the laws of Japan.
2. Any dispute between you and us relating to the App is subject to the exclusive jurisdiction of the district court having jurisdiction over our location, as the court of first instance.

16. Severability and entire agreement

1. If any provision of these Terms, or part of one, is held invalid or unenforceable under applicable law, the remainder of these Terms continues in full force and effect.
2. These Terms constitute the entire agreement between you and us regarding your use of the App, and supersede any prior agreement or representation.
3. Our failure to exercise a right under these Terms is not a waiver of that right.
