Terms of Service

Last updated: July 6, 2026

Article 1 (Application)

These Terms of Service (the "Terms") set out the conditions for using the PWA "Punchy" (formerly "AI Boxing Trainer"; the "Service") provided by Do the right thing (a sole proprietorship; the "Operator"). By using the Service, the user (the "User") is deemed to have agreed to these Terms.

Article 2 (Service Description)

The Service is a shadow-boxing practice-support application that provides real-time voice AI coaching and video analysis. Using the Google Gemini Live API and MediaPipe, it analyzes the User's movements and voice and generates coaching responses.

Article 3 (Conditions of Use)

  1. Authentication with a password issued by the Operator is required to use the Service.
  2. The User shall prepare an appropriate network environment, camera and microphone to use the Service.
  3. The Service is a closed beta; specifications may change without notice.
  4. Users under 13 may use the Service only with the consent and supervision of a guardian. Minors should use the Service only after obtaining a guardian's consent.
Article 4 (Important: Health Disclaimer and Assumption of Risk)
The Service is not a substitute for medical care, treatment or diagnosis. Exercise such as boxing inherently carries risks including falls, bruising, joint or muscle injury and other injuries. The User uses the Service at their own risk and discretion, having understood these risks and considered their own physical condition and health. If you have any concerns about exercise, or if you have heart or joint conditions, high blood pressure, a pre-existing condition, or are pregnant, please consult a physician before use. Perform a pre-exercise health check (condition, hydration, and a safe, clear space).
This Article applies except in cases of the Operator's intent or gross negligence (see Article 9).

Article 5 (Prohibited Acts)

The User shall not engage in any of the following.

  1. Acts that violate laws or public order and morals.
  2. Acts that infringe the rights of other users or third parties.
  3. Improperly probing or exploiting vulnerabilities of the Service.
  4. Sharing or transferring a password, token or purchase entitlement to a third party.
  5. Reverse engineering, decompiling, modifying, or redistributing the Service.
  6. Allowing any third party other than the User to use the Service (including sharing a purchase entitlement).
  7. Using paid features by improper means, or circumventing payment.
  8. Interfering with the Operator's business.
  9. Any other act the Operator deems inappropriate.

Article 6 (Nature of AI Responses and Disclaimer)

  1. The Service's AI responses are automatically generated by a machine-learning model (Google Gemini) and are not guaranteed to be accurate or complete. Camera recognition and form assessment have accuracy limits and may produce false detections or misjudgments.
  2. Whether the AI's coaching instructions are suitable for your physical condition is for you to judge. Stop immediately if you feel any strain or excessive load.
  3. The Service adopts a design principle of "not asserting what cannot be confirmed from video or detection data," but the possibility of the AI generating incorrect information cannot be entirely excluded. Do not over-rely on the AI's guidance.

Article 7 (Use of Camera and Microphone)

  1. The Service requests permission to use the camera and microphone. If not granted, the core features will not work.
  2. During training, camera video (still images at ~0.5 fps) and audio are sent in real time to the cloud (Google Gemini Live API) to generate AI coaching. Depending on your tier setting, video may not be sent.
  3. The handling of the video and audio is governed by the Privacy Policy.

Article 8 (Paid Plans and Payments)

  1. The Service offers certain features as a paid plan ("Premium"). Prices and conditions are shown within the Service and in the Notation based on the Act on Specified Commercial Transactions.
  2. Payment for Premium is provided by Paddle.com Market Limited ("Paddle") as the seller of record (Merchant of Record). That is, the seller that enters into the Premium sales contract with the User is Paddle, and the handling of card and billing information, taxation, invoicing, refunds and compliance with consumer laws in various countries are handled by Paddle. The Operator does not receive or store the User's credit card information.
  3. Premium is a subscription (recurring billing). Unless cancelled, it renews and is charged automatically on each renewal date.
  4. Cancellations, payment-method changes, refunds and billing inquiries are handled primarily by Paddle. You may cancel at any time; after cancellation, charging stops from the next renewal date onward. As a rule, we do not provide pro-rata refunds for already-charged periods (details follow the Notation based on the Act on Specified Commercial Transactions and Paddle's buyer terms).
  5. Purchases, cancellations and refunds are also governed by Paddle's Checkout Buyer Terms and Privacy Policy.

Article 9 (Limitation of Liability)

  1. The Operator does not warrant the completeness, accuracy, usefulness or fitness for a particular purpose of the Service.
  2. Except in cases of the Operator's intent or gross negligence, the Operator is not liable for damages arising from use of the Service. Even where the Operator is liable, such liability is limited to ordinary, direct and actual damages, and excludes indirect damages, special damages, lost profits and the like.
  3. Even where the Operator bears liability for damages (except in cases of intent or gross negligence in the preceding paragraph), the cap on that liability is the amount the User paid to the Operator over the preceding six months (or JPY 0 for free use).
  4. This Article does not apply to the extent it is void under the Consumer Contract Act or other mandatory law.

Article 10 (Changes to or Termination of the Service)

The Operator may change the content of, or terminate, the Service within a reasonable scope. In case of termination, we will announce it within the Service in advance where possible. The Operator's liability for any resulting damage to the User is limited as set out in the preceding Article.

Article 11 (Intellectual Property)

Intellectual property rights in the software, content, design and trademarks included in the Service belong to the Operator or the rightful right holders. The User shall not use them beyond the scope necessary to use the Service.

Article 12 (User Content)

Information such as a nickname entered by the User is stored on the device. The Operator handles it only to the extent necessary to provide the Service and does not sell or provide it to third parties.

Article 13 (Handling of Personal Information)

The handling of personal information is as set out in the Privacy Policy. Payment-related information is handled independently by Paddle.

Article 14 (Changes to These Terms)

The Operator may change these Terms as necessary. Material changes will be announced within the Service or on the home page. If the User uses the Service after a change, the User is deemed to have agreed to the changed Terms.

Article 15 (Governing Law and Jurisdiction)

These Terms are governed by the laws of Japan. In the event of a dispute between the Operator and the User regarding the Service, the court having jurisdiction over the Operator's location shall be the exclusive agreed court of first instance. This does not, however, prejudice any jurisdiction available to consumers under mandatory consumer-protection law.
