NumBubble Terms of Use

Effective date: September 14, 2026

These Terms of Use (the "Terms") govern use of the NumBubble game application (Japanese name: ナンバブル; the "App") provided by CHOIGE STUDIO (Japanese name: ちょいゲースタジオ; "we," "us," or "our"). By using the App, you agree to these Terms.

1. Conditions of Use

You must use the App in compliance with these Terms and applicable law.

Use of the App may require a compatible device, operating system, and internet connection. You are responsible for connection charges and other costs associated with use of the App.

2. Rankings and Player Names

The App uses an anonymous account to provide scores, personal bests, and rankings. Player names, scores, and ranking positions are visible to other users.

You can delete the anonymous account and its associated play data from the App's settings. Deletion cannot be undone, and deleted data cannot be restored. Removing the App from your device alone does not delete data stored on our servers.

You must not use a player name that contains:

• Personal information about you or another person
• Content that impersonates another person
• Harmful, discriminatory, sexual, or violent content
• Content that violates law, public policy, or the rights of another person
• Advertising, solicitation, contact details, or other content unrelated to the game

We may hide, change, or remove inappropriate player names or scores and restrict ranking submissions.

3. Prohibited Conduct

You must not:

• Interfere with the operation of the App, servers, rankings, or advertising
• Create or submit scores by unauthorized means
• Probe for vulnerabilities, bypass authentication or access controls, or send excessive requests
• Modify, analyze, copy, or redistribute the App, except where applicable law permits it
• Infringe the rights of another person
• Engage in other conduct that we reasonably consider inappropriate

4. Advertising and Third-Party Services

The App may display third-party advertising. Advertisements, advertised products or services, and external services are provided under the responsibility of their respective providers. A provider's terms apply when you use its advertisement or service.

5. Intellectual Property

Copyrights, trademarks, and other intellectual property rights in the App belong to us or their lawful owners. These Terms grant only a limited right to use the App for personal, non-commercial purposes.

6. Changes and Suspension

We may change, suspend, or discontinue the App or features such as rankings for maintenance, failures, security, legal compliance, operational reasons, or other reasons. We will provide notice where reasonably possible, but urgent changes may occur without advance notice.

If an App update is required, some or all features may stop working in older versions.

7. Disclaimer

The App is provided as available. We do not guarantee that the App will always be available, error-free, suitable for a particular purpose, or that scores and rankings will be stored permanently.

8. Limitation of Liability

Except in cases of our willful misconduct or gross negligence, or where applicable law does not allow a limitation, we are not liable for indirect, incidental, special, or consequential loss arising from use of or inability to use the App. This section does not limit rights available to users under mandatory consumer protection or other applicable law.

9. Restrictions on Use

If you violate these Terms, or if needed to protect the service or other users, we may restrict ranking submissions, visibility, or other features.

10. Changes to These Terms

We may update these Terms to reflect changes to the App, services, or applicable law. If a change is material, we will provide notice through the App, the published Terms page, or another appropriate method. By continuing to use the App after the change, you agree to the updated Terms, unless applicable law requires a different process.

11. Governing Law and Jurisdiction

These Terms are governed by the laws of Japan. To the extent permitted by applicable law, courts in Japan with jurisdiction over our location will have exclusive jurisdiction in the first instance over disputes concerning the App. This section does not affect rights under mandatory consumer protection laws applicable in the user's place of residence.
