Terms of Use

The App is a brain training application designed for users to enjoy tasks involving memory, calculation, language, attention, parallel processing, and other activities in game form.

Users shall use the App in accordance with these Terms and applicable law.

The "brain age", scores, rankings, performance records, and other results displayed by the App are reference information calculated using the App's own rules and calculation methods.

These results do not measure or diagnose actual biological age, medical brain function, cognitive function, or other health conditions.

The App is not provided for the purpose of medical diagnosis, testing, treatment, disease prevention, or other medical procedures.

Please do not make health or medical decisions based solely on results from using the App. If you have concerns about your health, please consult a doctor or another appropriate professional.

We also do not guarantee that using the App will improve cognitive abilities, memory, or other abilities.

The App may offer ad removal and other paid features.

In-app purchases are processed through the App Store payment system provided by Apple.

Purchase prices and other conditions are as displayed in the App Store or the App at the time of purchase.

Apple's terms and procedures apply to purchase cancellations, refunds, and other payment-related matters.

We do not directly collect users' credit card numbers or similar information.

It may be possible to restore the purchase status of purchased features within the mechanisms provided by Apple and the App.

The App may display advertisements provided by third parties.

Advertisers or other third parties are responsible for the content of advertisements and the products or services they advertise.

If users access third-party products or services through advertisements, the resulting transaction is between the user and that third party.

Users must not engage in the following conduct when using the App.

Copyrights, trademark rights, and other intellectual property rights in the programs, designs, images, characters, text, audio, game expressions, and other content included in the App belong to us or to third parties holding legitimate rights.

These Terms do not transfer any of these intellectual property rights to users.

Users must not reproduce, modify, distribute, sell, or otherwise use the App's content beyond the scope permitted by law or separately and expressly authorized.

The App may use services provided by third parties to provide analytics, in-app purchases, advertising, contact functions, and other features.

Use of third-party services may be subject to the terms of use, privacy policies, and other conditions established by their respective providers.

We may change the App's content, specifications, games, score calculation methods, and other features to improve quality or functionality, address security issues, or for other reasons.

As a result, past scores or results may no longer be directly comparable with future scores or results.

We may temporarily suspend or discontinue all or part of the App in the following circumstances.

We do not guarantee the App's safety, accuracy, completeness, usefulness, fitness for a particular purpose, continuous availability, freedom from errors or bugs, or similar qualities.

All or part of the App may be unavailable depending on the usage environment, device, operating system, communication conditions, or other circumstances.

However, this section does not exempt us from liability under applicable law.

We endeavor to provide the App appropriately and safely.

Our liability for damages suffered by users as a result of using or being unable to use the App shall be governed by applicable law.

No provision of these Terms exempts or limits liability arising from our intentional misconduct or gross negligence, or any other liability that cannot legally be excluded or limited.

If minors use the App, purchase paid features, or provide personal information, they should obtain the consent of a parent, guardian, or other legal representative as necessary before doing so.

The handling of user information in the App is governed by the separately established Privacy Policy.

If you obtained the App from Apple's App Store, Apple's terms and the Standard End User License Agreement (Standard EULA) may apply in addition to these Terms.

If these Terms conflict with applicable law or mandatory terms applicable between you and Apple, those laws or terms take precedence.

We may change these Terms in response to changes in the law, changes to the App, or where otherwise reasonably necessary.

If we make changes that significantly affect users' rights or obligations, we will notify users of the changes and their effective date by displaying a notice within the App, posting it on this website, or by other reasonable means.

The revised Terms take effect on the displayed effective date.

If any provision of these Terms is determined to be invalid or unenforceable under law or otherwise, the remaining provisions shall remain valid.

These Terms are governed by and interpreted in accordance with the laws of Japan.

If a dispute arises concerning the App or these Terms, the Japanese court having jurisdiction over our location shall be the agreed court of first instance, unless otherwise provided by applicable law.
