Terms of Use

Effective: October 31, 2026

These Terms of Use ("Terms") set out the conditions for using ZENnoMA, provided by YenSense Inc. ("we", "us"), including the iPhone and iPad app, the web app, the browser extension and related services (the "Service"). By using the Service, you ("you", the "user") agree to these Terms.

1. Scope

1. These Terms apply to all relationships between you and us regarding the use of the Service.
2. Individual rules we present in the Service (such as prices, subscription conditions and notices) form part of these Terms.

2. Your account

1. You need to sign in with an Apple or Google account to use the Service.
2. Your account is for you alone. You may not let others use, lend, transfer or share your account.
3. One account can be used on up to one device in the app (iPhone or iPad) and one in a web browser at a time. Signing in on a new device signs out the previous device of the same kind.
4. Keep the information you register, such as your username, accurate. Do not use a name that infringes others' rights or is offensive.
5. The Service is not available to children under 13. If you are a minor, use the Service with the consent of a parent or legal guardian.

3. Paid plans

1. Some features are available through a paid subscription (a "Paid Plan"). The price, the subscription period and any free trial are shown on the purchase screen.
2. A Paid Plan renews automatically on the same terms at the end of each period unless you cancel it.
3. Purchases on iPhone and iPad are made through Apple's App Store, and payment, renewal, cancellation and refunds follow Apple's terms. To cancel, do so in your device's Settings (Apple ID → Subscriptions) at least 24 hours before the next renewal date.
4. Purchases on the web are made through a payment service we designate. You can cancel from the subscription management screen in the Service before the next renewal date.
5. If a free trial is offered and you do not cancel before it ends, your subscription automatically converts to a Paid Plan and you will be charged when the trial ends.
6. Except as required by law, fees already paid are non-refundable. Refunds for App Store purchases are handled through Apple's procedures.
7. Your records and data are not deleted when a Paid Plan ends (unless you delete your account).

4. Nature of the Service

1. The breathing, meditation and focus features are meant to support your daily focus and life. They are not medical care, diagnosis or treatment. If you have health concerns or a respiratory or cardiovascular condition, consult a doctor before use. Stop immediately if you feel unwell while breathing.
2. Features such as closing apps (which use Apple's Screen Time framework), notifications and alarms may not always work as intended, depending on your device and operating system. Do not rely solely on the Service for important events or alarms.
3. Reading calendar and Health data and the settings for closing apps are handled on your device. See our Privacy Policy for details.

5. Prohibited conduct

When using the Service, you must not:

1. violate laws or public order and morals;
2. share your account with others or let others use it;
3. place an excessive load on, or gain unauthorized access to, our servers or networks;
4. modify, decompile, disassemble or reverse engineer the Service (except as permitted by law);
5. interfere with the operation of the Service;
6. impersonate others or infringe the rights or interests of others; or
7. do anything else we reasonably consider inappropriate.

6. Intellectual property

All intellectual property rights in the text, images, sounds and software of the Service belong to us or the rightful owners. The content you enter, such as your plans and records, belongs to you. We store and process it only as needed to provide the Service.

7. Changes, interruptions and termination of the Service

1. We may change the Service or end it. If we end the Service, we will give notice in the Service a reasonable time in advance.
2. We may suspend all or part of the Service temporarily without notice for maintenance, failures, natural disasters or other unavoidable reasons.

8. Suspension and account deletion

1. If you violate these Terms, we may suspend or delete your account without notice.
2. You can delete your account at any time from My Page in the Service. When you do, your data on our servers is deleted. Cancelling a Paid Plan is separate from deleting your account (cancel App Store subscriptions in your Apple ID settings).

9. Disclaimers and limitation of liability

1. We do not guarantee that the Service will fit your particular purpose, produce the results you expect, or be free of defects or interruptions.
2. We are not liable for damages you suffer in connection with the Service, except where caused by our intent or gross negligence. This does not apply where our contract with you is a consumer contract under Japan's Consumer Contract Act. Even then, our liability for damages caused by our negligence (other than gross negligence) is limited to ordinary damages actually incurred, up to the amount you paid us in the month the damage occurred.

10. Changes to these Terms

We may change these Terms when necessary. We will announce the changes and their effective date in the Service or on this page a reasonable time before they take effect. If you use the Service after the changes take effect, you are deemed to agree to the changed Terms.

11. Communication

We contact you through notices in the Service or other means we consider appropriate. Please contact us at the address below.

12. Governing law and jurisdiction

These Terms are governed by and construed in accordance with the laws of Japan. Any dispute between you and us regarding the Service shall be subject to the exclusive jurisdiction of the district court having jurisdiction over our head office, as the court of first instance.

13. Language

These Terms are available in Japanese and English. If there is any discrepancy, the Japanese version prevails.
