ShapeGap Terms of Use

Effective date: September 11, 2026 / Last updated: October 6, 2026

1. Application

These Terms of Use ("Terms") govern your use of the application "ShapeGap" (the "App") provided by Toshiki Sakuraya (the "Operator"). By using the App, you agree to these Terms.

2. Definitions

"Plan" means a proposed training and nutrition plan that the App generates from your goals, body data, and other inputs.
"Approved Plan" means a Plan you have reviewed and approved.
"Records" means your workout logs, food logs, body measurements, body photos, and any other information you store in the App.

3. Eligibility

You must be at least 18 to use the App. Select the age range that matches your age.

No email or password registration is needed. Records and photos are stored on your device. You are responsible for controlling access to that device.

Delete all also removes drafts, derived observations, temporary sharing files and scheduled notifications. It deletes any guest account created for you and its server-side usage allowance. If server deletion fails, credentials are retained so you can retry. Plans do not transfer to a new device. Export lets you take a copy of your data; it does not restore plans.

4. Paid Features and Subscriptions

Prices, billing periods, and free-trial terms are shown on the purchase screen in the App and on the App Store listing for your region. (For Japan, the current price is ¥980/month or ¥6,800/year, tax included.)
Payment is processed through Apple's in-app purchase system.
Subscriptions renew automatically unless canceled.
To cancel, go to your device settings (Settings > your name > Subscriptions) at least 24 hours before the renewal date. After cancellation, you keep access to paid features until the end of the paid period.
Refunds are handled under Apple's policies. The Operator cannot issue refunds directly.

Weekly plans renew each week and monthly plans renew each month, where offered. Annual plans are billed in full each year. In Japan and South Korea, eligible monthly subscribers receive a seven-day free trial. Annual plans and plans in other countries and regions have no free trial. The monthly price shown at purchase is charged after the trial ends. Cancel at least 24 hours before the trial ends if you do not want to continue. Deleting App data does not cancel a subscription.

See Apple's instructions for cancellation and refund requests.

5. User Content

You retain all rights to your Records, including body photos.
The Operator uses your Records only as needed to provide the App's features. Photos, body measurements and health information are never used in advertising or promotion. Other Records will not be used in advertising or promotion without your separate, explicit consent.

6. Third-party rights

Only import images you have the right or permission to use. Do not infringe copyright, portrait rights or other third-party rights. This applies to celebrity photos and images from other people's social media posts.

Photo processing and all comparisons take place on your device. Progress photos are never sent. Your current and goal photos are sent only when you create a plan with AI design and have consented. The Operator cannot remotely view or delete local photos. If a rights holder reports an infringement, the Operator may ask you to remove the image or otherwise address the report.

You are responsible for resolving disputes arising from the images you import at your own expense, except where the dispute results from the Operator's willful misconduct or gross negligence.

7. AI plan design

AI selects exercises and their allocation when designing a plan. When you request a plan, we send your current and goal photos, height, body weight (rounded to a whole number), sex, age range, goal, the necessary questionnaire answers, visual comparisons you have confirmed for six groups (shoulders, back, chest, arms, waist and legs), and training conditions. We explain what will be sent and the recipient's role and obtain consent before transmission.

Requests pass through the Operator's relay server. It manages credentials and usage allowances without storing request or response content. After you consent to AI use, we create an anonymous guest account on the relay server. It identifies your device and manages your server-side usage allowance. If you decline, no guest account is created and plans are generated on your device. We do not send your name, progress photos, geometric ratios, contact details, condition names, food logs or step counts.

AI plans are not medical diagnosis or treatment. Their accuracy and completeness are not guaranteed. Plans must pass validation and receive your approval before they take effect. Approved plans cannot change without your consent. Progression and nutrition calculations follow fixed rules.

8. Medical Disclaimer

The App provides general fitness information and logging features. It is not a medical device and is not intended to diagnose, treat, or prevent any disease. Nothing in the App is a substitute for the judgment of a physician or other qualified professional.

9. Training safety

Exercise carries a risk of injury. Adjust training to your condition and ability. Stop immediately if you experience chest pain or severe dizziness, or if breathing becomes unusually difficult. Seek medical help when needed. The App does not give clearance to resume exercise.

A single checkbox confirms that none of these apply: a doctor has restricted your exercise, you are pregnant, or you are receiving treatment for an eating disorder. We do not ask for separate condition or pregnancy entries. The only health-check information saved is its completion time (safetyAttestedAt), kept on your device.

If any of these apply or you have health concerns, consult a doctor and do not use weight-loss settings. You can choose "Do not use weight-loss phases" yourself. This setting is not a health question, and we do not record your reason for choosing it.

10. Prohibited Conduct

You must not engage in any of the following:

Violating laws or public order
Decompiling, reverse engineering, or otherwise analyzing the App
Accessing another user's Records without authorization
Misrepresenting your age or other information you provide
Interfering with the operation of the App
Commercial use not authorized by the Operator
Any other conduct the Operator reasonably deems inappropriate

11. Changes, Suspension, and Termination of the Service

The Operator may change the App. Material changes will be announced in the App or on this site.
The service may be temporarily suspended for maintenance, system failure, or events beyond the Operator's control.
If the service is discontinued, the Operator will give reasonable advance notice and explain how your data will be handled, including export options.

12. Limitation of Liability

The Operator does not guarantee that the App is complete, accurate, or fit for a particular purpose.
Except in cases of willful misconduct or gross negligence, the Operator's liability for damages arising from your use of the App is limited to direct and ordinary damages, up to the total fees you paid to the Operator in the preceding 12 months.
Nothing in this section limits rights you hold under mandatory consumer-protection laws.

13. Changes to These Terms

The Operator may amend these Terms. The effective date and the changes will be announced in advance in the App or on this page. Continued use of the App after the effective date constitutes acceptance of the amended Terms.

14. Governing Law and Jurisdiction

These Terms are governed by the laws of Japan.
Unless mandatory law provides otherwise, the Tokyo District Court has exclusive jurisdiction in the first instance over disputes relating to the App.

15. Additional Terms for Distribution via the App Store

If you obtained the App from Apple's App Store, the following also applies.

These Terms are an agreement between you and the Operator, not with Apple. The Operator, not Apple, is solely responsible for the App and its content.
The Operator grants you a non-transferable license to use the App on Apple-branded products that you own or control, as permitted by the Usage Rules set out in the App Store terms, except that the App may be accessed and used by other accounts associated with you via Family Sharing where the Usage Rules allow.
The Operator is solely responsible for providing any maintenance and support for the App. Apple has no obligation whatsoever to furnish maintenance or support.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. Any other claims, losses, or liabilities attributable to a failure to conform to a warranty are the Operator's sole responsibility.
The Operator, not Apple, is responsible for addressing any claims by you or a third party relating to the App or your possession or use of it, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection or similar laws.
If a third party claims that the App infringes its intellectual property rights, the Operator, not Apple, is solely responsible for the investigation, defense, settlement, and discharge of the claim.
You represent and warrant that you are not located in a country subject to a U.S. Government embargo and that you are not listed on any U.S. Government list of prohibited or restricted parties.
Questions, complaints, or claims regarding the App should be directed to the Operator (Toshiki Sakuraya, email: rebirth.sakuraya@gmail.com). The Operator's address will be disclosed without delay upon request.
You must comply with applicable third-party terms of agreement (such as your wireless data service agreement) when using the App.
Apple and Apple's subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple will have the right, and will be deemed to have accepted the right, to enforce these Terms against you as a third-party beneficiary.
