Last revised: 2026-06-17 / Established: 2026-06-10

This English text is a translation provided for convenience. In case of any discrepancy, the Japanese version prevails.

These Terms of Use (these "Terms") set out the conditions for using the iOS / watchOS application "Feelmo" (the "App") and the websites feelmo.jp and docs.feelmo.jp (together, the "Service"), provided by Taro Ueno (上野太郎) (the "Provider"). By using the Service, you are deemed to have agreed to these Terms.

Please note that the App is currently provided by the Provider as an individual.

1. Definitions

The terms used in these Terms are defined as follows.

"App" means the iOS / watchOS application "Feelmo" provided by the Provider
"Sites" means the websites provided at feelmo.jp and docs.feelmo.jp
"User" means anyone who uses the Service
"App Store" means the App Store operated by Apple Inc. ("Apple"), through which the App is distributed
"Paid Plan" means "Feelmo Premium," which provides additional features of the App for a fee
"Subscription" means the provision of the Paid Plan on a recurring billing basis, or the access right thereto
"Free Trial" means a trial period during which a Subscription may be used free of charge for a certain period

2. Purpose and Nature of the Service

The Service is a wellbeing tool for observing and recording autonomic balance (the Balance score) and supporting daily self-care
The Service is not a medical device and is not intended to diagnose, treat, or prevent any disease. The displays and suggestions of the Service gently convey "tendencies" in your autonomic balance; do not use them as a basis for medical decisions
If you have any health concern or symptom, always consult a physician or other medical professional, regardless of your use of the Service. Details concerning health and medical matters are set out in Article 13

3. Accounts

The App does not require account registration or login. A User's records are handled within the User's device, and the Provider does not create or manage User accounts. Accordingly, these Terms contain no provisions concerning membership registration, withdrawal, or ID/password management.

4. Operating Environment

Using the App requires an iPhone running iOS 17.0 or later. Reading the Balance score requires an Apple Watch
The devices, communication environment, and communication costs necessary to use the Service are the User's responsibility. Changes to the device, phone number, or OS version, international roaming, a change of carrier, or similar circumstances may render some or all features unavailable

5. Eligibility

Users under 18 should use the Service with the consent of a parent or guardian.

6. Third-Party Services (Apple, etc.)

The App uses Apple's platforms (the App Store, HealthKit, etc.). In addition to these Terms, the User shall comply with the terms and policies established by Apple
Apple is not a party to these Terms; however, Apple, as a third-party beneficiary of these Terms, may enforce these Terms against the User. The Provider, not Apple, bears the primary responsibility for warranties, support, product liability, and the like relating to the App (as provided by Apple)
With respect to external services or linked destinations other than the Service provided by the Provider, the Provider is not responsible for their content or for transactions between the User and such third parties

7. Intellectual Property

Intellectual property rights in the programs, designs, text, images, characters (including Energetic, Calm, Neutral, Anxious, Overload, and Tired), trademarks, and all other content that make up the Service belong to the Provider or the rightful owners
The User may not reproduce, modify, distribute, publicly transmit, or otherwise use these beyond private use or as otherwise permitted by law
Sharing screenshots for personal, non-commercial purposes (such as posting to social media) is welcome. When doing so, please refrain from altering the content or using it in a manner that could be mistaken for the Provider's official communications

8. Prohibited Acts

In using the Service, the User must not engage in the following acts.

Using the Service as a basis for medical diagnosis or treatment decisions
Reverse-engineering, decompiling, or disassembling the App or its components (except where permitted by law)
Reproducing, redistributing, lending, selling, or sublicensing the Service
Infringing the intellectual property, privacy, reputation, or other rights of the Provider or third parties
Attempting to identify (re-identify) individuals from anonymized information
Using automated programs or the like to impose an excessive load on the Service in a manner that differs from ordinary use, gaining unauthorized access, or interfering with the operation of the Service
Violating laws or public order and morals

9. Paid Plan (Feelmo Premium) and Subscription

The Provider may offer a paid plan, "Feelmo Premium," as an additional feature of the App. Basic features, such as the measurement loop, are available free of charge
The purchase, billing, cancellation, and refund of the Paid Plan follow the rules established by Apple's App Store. The fees and the content of the features will be announced within the App and on the Sites at the time the plan launches
Automatic renewal: Unless the User cancels, a Subscription automatically renews on the same terms and is billed for each period selected by the User (monthly, yearly, etc.)
Cancellation: You can cancel at any time via "Settings → Apple ID → Subscriptions" in iOS. Cancellation takes effect from the next renewal date, and fees for the period already elapsed are not refunded (per Apple's policies)
Free Trial: The Provider may offer a Free Trial for a certain period. If you do not cancel before the Free Trial period ends, it automatically converts to a paid Subscription and is billed. As a general rule, a Free Trial is limited to one per Apple ID
Changes to fees: The Provider may change the fees or terms of provision. Changes apply from the next renewal, and the Provider will endeavor to provide reasonable advance notice. If the User does not agree to the changed terms, the User may cancel before the applicable date
Refunds: Refunds are handled in accordance with Apple's refund policy. Please submit refund requests to Apple
Fees may vary depending on the country of payment, exchange rates, taxes, and Apple's policies

10. In-App Text

The gentle words of observation and summaries shown by the App are composed within the User's device (records are not transmitted outside the device)
The text shown by the App gently conveys general insights and "tendencies" in your autonomic balance; it is not medical, psychological, or other professional advice, diagnosis, or treatment
The Provider does not warrant the accuracy, completeness, or fitness for a particular purpose of the displayed content. The User shall refer to the displayed content at the User's own discretion and responsibility

11. Handling of Data

The handling of User information in the Service is governed by the Privacy Policy.

12. Data Storage and Device Changes

Among the App's data, your records (mood logs, sleep, breathing, learned baselines, and other HealthKit-derived health information and data derived from it) are stored only on your device and are not stored in iCloud (in conformity with Apple's guidelines). If the User enables iCloud Sync in Settings, the only thing synced is your "settings" (notifications, appearance, etc.), which contain no health data; these are synced across other devices on the same Apple ID through your own iCloud. In this case, syncing takes place in Apple's iCloud and is not transmitted to or stored on the Provider's servers
Because records are stored only on your device, they cannot be transferred to, or restored on, a new device in cases such as device failure, loss, or replacement (the source data for HRV, sleep, and the like is accumulated in Apple Health, so carrying Apple Health over lets the App read it again on a new device)
The User shall manage their own data at their own responsibility. For loss of on-device data, the Provider is liable only as set out in Article 16

13. Health and Medical Disclaimer

The Service is intended for informational purposes only; it is not a medical device and is not designed or provided to diagnose, prevent, or treat any disease or symptom. Nor is it a substitute for professional medical care
The Service does not provide emergency medical services. In an emergency, immediately use a medical institution or emergency services
You must not, on the basis of information obtained through the Service, disregard professional medical advice or delay consulting a medical institution
The effects or results of using the Service may vary depending on the User's health condition and other factors, and the Service does not guarantee any particular result
Some features of the Service (such as breathing sessions) may not be suitable for all Users. Please refrain from using the Service while driving, operating machinery, or in other situations requiring attention and concentration. The User bears responsibility for their own use of the Service

14. Disclaimer of Warranties (As-Is)

The Service is provided "as is" and "as available." To the maximum extent permitted by law, the Provider does not warrant that the Service is free of defects in fact or law (including safety, reliability, accuracy, completeness, usefulness, fitness for a particular purpose, compatibility with other software or services, or freedom from interruptions or errors)
The preceding paragraph does not limit the application of the Consumer Contract Act or other mandatory laws, and does not apply to the extent it would be invalid under such laws

15. Changes, Suspension, and Termination of the Service

The Provider may change, suspend, or terminate all or part of the Service upon prior notice to the User. However, in unavoidable cases such as defect response, emergency updates, or natural disasters, notice may be given after the fact
As the App runs within the device, the Provider will endeavor, to a reasonable extent, to keep on-device data accessible and exportable even after the Service ends

16. Disclaimer and Limitation of Liability

The Provider is not liable for any damage incurred by the User as a result of using the Service, except where the Provider has acted with willful misconduct or gross negligence
Even where the Provider is liable, the Provider's liability is limited to ordinary and direct damages, and is capped, for Paid Plan Users, at the total fees that the User actually paid through the Service in the preceding 12 months, and, for Users who use the Service free of charge, at JPY 10,000
The preceding two paragraphs do not limit the application of the Consumer Contract Act or other mandatory laws, and do not apply to the extent they would be invalid under such laws

17. User Responsibility

If the User violates these Terms or causes damage to the Provider or a third party in connection with the use of the Service, the User shall resolve the matter at their own responsibility and expense and shall compensate the Provider for any damage incurred (including reasonable attorneys' fees).

The User represents and warrants that the User is not a member of organized crime groups or other anti-social forces (the "Anti-Social Forces") and has no relationship with Anti-Social Forces
If it becomes apparent that the User is an Anti-Social Force, the Provider may suspend the provision of the Service without any notice or demand

19. Prohibition of Assignment of Rights and Obligations

The User may not, without the Provider's prior written consent, assign to a third party, or provide as collateral, their status under these Terms or any rights or obligations based on these Terms.

20. Amendments to the Terms

The Provider may amend these Terms in accordance with Article 548-4 of the Civil Code of Japan
When amending these Terms, the Provider will give notice of the content of the amended Terms and the date on which they take effect, by posting on the Sites or by other appropriate means, a reasonable period before the effective date
If the User uses the Service after the amendment takes effect, the User is deemed to have agreed to the amended Terms

The User may convey opinions or complaints about the use of the Service to the Provider through the contact point set out in Article 27. The Provider will respond as promptly as possible, and where a prompt response is difficult, will endeavor to inform the User of the reason and the anticipated handling
If a dispute arises between the Provider and the User concerning the Service, the parties shall first seek to resolve it through good-faith consultation. The User may also use the nearest Consumer Affairs Center (the Consumer Hotline "188") or other consultation services

25. Jurisdiction

If a dispute arises between the Provider and the User concerning the Service and resolution through litigation becomes necessary, the Tokyo District Court shall be the court of exclusive agreed jurisdiction in the first instance
However, where the User is a consumer, the preceding paragraph does not preclude the court jurisdiction granted to the User by the Consumer Contract Act or other mandatory laws (including the filing of suit in the court having jurisdiction over the User's place of residence)

26. Overseas Users and Export Control

Even if the User resides outside Japan, these Terms are governed by the laws of Japan. However, these Terms do not preclude the protections guaranteed to consumers by the mandatory laws of the User's country of residence. Consumers in the European Union (EU) receive the protections of the mandatory provisions of their country of residence
The User represents and warrants that (i) the User does not reside in a country or region subject to economic sanctions, and (ii) the User is not listed on any list designating persons prohibited or restricted under the export control laws and regulations of any country
