These Terms of Use (“Terms”) set out the conditions for using the mobile application “ninepi GYMemo” (“App”) provided by Ninepi Corporation (“Company”). Users must agree to these Terms before using the App.

These Terms apply to the regular features of the App, rankings, advertisements, and the optional AI Trainer. Use of AI Trainer requires a separate monthly GYMemo PRO subscription. Rights from a Standard purchase already made remain in place and are separate from a PRO subscription.

Article 1 (The App)

  1. The App lets users record workout menus and results on their devices, and review and summarize them.
  2. The App does not provide medical care, diagnosis, treatment, rehabilitation, or professional exercise instruction.
  3. Records are generally stored on the user’s device. If the user enables rankings under Article 4-2, information needed to provide rankings is sent to and stored on an external server used by the Company. This is not a backup or restoration service. Information sent is described in Article 4-2; details of handling are in the separate Privacy Policy.

Article 2 (Required Environment)

  1. Users must prepare, at their own expense and responsibility, a compatible device and OS, an Apple Account or Google Account, internet access, and any other environment needed to use the App.
  2. Changes to devices, OS, App Store, or Google Play specifications may make all or part of the App unavailable.
  3. The App has no account registration or login using an email address. Ranking participation uses a participant ID randomly generated on the device.

Article 3 (Free Use)

  1. Workout recording, summaries, and personal-best review are available indefinitely without purchase. Free displays no ads for the first 30 days after installation and displays ads from day 31. The recording and editing features do not stop after 30 days.
  2. Users can use data save and load and CSV export. Data saving and CSV export require Standard or PRO; data import is free.
  3. The App does not use free-trial products offered through App Store or Google Play. Using Free or the end of a free period does not start automatic billing. Users must make a purchase themselves to use paid features.
  4. The AI Trainer free trial is separate from free use of the App’s regular features. Its conditions are in Article 4.
  5. Without a purchase, users may continue to view past records; see daily, weekly, monthly, and yearly summaries; view muscle-group and exercise breakdowns; review personal bests and progress; view exercise details; change display settings; and import data.
  6. Deleting and reinstalling the App may change how on-device records or trial information are displayed or determined, depending on the device and OS. Make a copy of necessary records using the available data-save feature.

Article 4 (Purchases and Fees)

  1. Standard is a one-time purchase for JPY 500 (tax included). It provides ad-free use, data saving and loading, and CSV export. Rights from existing one-time purchases are maintained.
  2. Depending on the device, a one-time in-app purchase is made through App Store or Google Play. The price is charged to the payment method set for the user’s Apple Account or Google Play account when the purchase is completed. Check the price and conditions shown on the purchase screen before confirming.
  3. Paid features become available after App Store or Google Play completes the purchase and the App confirms the purchase status. Confirmation may take time depending on network conditions.
  4. Data saving and CSV export are paid features and are unavailable before purchase, even during the 30-day free period from first launch. They become available immediately after purchase, regardless of the remaining free period. Data import, including importing data saved by another app, is free and available at any time, whether or not a purchase was made.
  5. Purchases, billing, and refunds are subject to the terms and procedures of the App Store or Google Play used for the purchase. Refunds follow the relevant store’s refund procedures. This does not limit rights under applicable law.
  6. PRO is an automatically renewing subscription for JPY 180 per month (tax included). It provides AI Trainer, ad-free use, data saving and loading, and CSV export. Standard need not be purchased first. AI Trainer is subject to region, usage, and other conditions.
  7. Check PRO’s price, subscription period, and renewal conditions on the App Store or Google Play screen before confirming. PRO renews for each subscription period until canceled.
  8. Cancel PRO in the subscription management screen of the App Store or Google Play used for purchase. Deleting the App does not cancel it. PRO remains available until the end of the paid period after cancellation.
  9. AI Trainer can be tried free for 30 days from installation, up to 10 times in total and no more than twice a day. Conditions may change. Check the App for the latest conditions. The free trial does not start automatic billing when it ends. Continued use requires the user to subscribe to PRO.
  10. If the Company offers a campaign such as free AI Trainer use, its duration, eligible users, number of uses, first-come limits, and other conditions will be announced in in-app notices. A campaign ends when its conditions are met; the Company may change or stop it when needed for operations. Purchase rights already obtained are not lost.

Article 4-2 (Rankings)

  1. Rankings are a free additional feature and are not included in the price of the one-time purchase under Article 4. They are free regardless of purchase status or whether the free period is ongoing or over. The user pays any network charges.
  2. Participation is optional and OFF by default for new users. Users may turn it ON in Settings after reviewing and agreeing to the information sent and the disclosure scope. It can be turned OFF at any time. Importing a file made during participation restores participation status. Non-participation does not change the conditions for other App features.
  3. When participation is ON, the App sends and stores on the Company’s server a randomly generated participant ID, display nickname, age group, sex category, participation status, workout date, exercise ID, daily totals by exercise (total weight, sets, repetitions, and maximum weight), update times, and related information for calculating and displaying rankings and preventing abuse. Information needed to authenticate submissions is also used. Names, dates of birth, email addresses, free-text notes, the weight-and-repetition combination for each set, and exact workout times are not sent. Do not enter a real name or contact information as a nickname if you do not want it disclosed.
  4. Other users may see a masked nickname, rank, ranking totals, age group, and sex category. Filtering by age group or sex may reveal a participant’s category.
  5. Rankings are for reference and are based on records entered by users; they do not accurately assess strength or physical ability. Comparisons are limited by the characteristics of each exercise. To prevent fraudulent entries, the Company may exclude records above a specified limit from ranking calculations. This does not delete device records.
  6. Based on operational circumstances such as termination of an external server contract, operating costs, or abuse prevention, the Company may change, suspend, or end rankings. Important changes or termination will be announced under Article 9(2).
  7. A change, suspension, or end of rankings does not remove or restrict rights to features purchased once. Since rankings are not included in the purchase price, no refund or compensation is provided solely because rankings change, pause, or end. This does not release the Company from liability for breach of contract or tort, or limit refund or other rights under applicable law. Any Company liability is governed by Article 10.
  8. Turning participation OFF stops future transmission and display of ranking data. To delete data already stored on the server, separately use ranking-data deletion in Settings. This deletes the participant profile and daily ranking totals.

Article 5 (Data Saving and Copies)

  1. Workout records are generally stored on the user’s device. When the user initiates Switching phones, encrypted records are held temporarily to move them to a new phone. Information sent and stored for rankings is described in Article 4-2.
  2. Records may be lost because of device failure, loss or replacement, App deletion, OS updates, data corruption, or other circumstances.
  3. Data saving and CSV export are paid features under Article 4 and are unavailable before purchase, including during a free period. Data import, including importing files saved by another app, is free whether or not a purchase was made.
  4. Users who can use data saving after purchase are encouraged to export necessary records regularly and store them safely. Users who cannot save data because they have not purchased a paid feature are not required to make such a purchase.
  5. The Company does not provide long-term or automatically updated backups. Switching phones temporarily holds encrypted records; once received, or after 24 hours, they can no longer be received and are deleted from regular storage (they may remain in maintenance backups for a limited time). The receiving phone’s records are replaced; the old phone’s records remain. Information sent for rankings cannot restore lost device records. This does not exempt the Company from legal responsibilities.
  6. A copy file may include user-entered information, a ranking participant ID, participation status, and ranking authentication information. Importing a file created during participation restores participation status and authentication information. A third party who obtains authentication information could change or delete ranking information; do not share copy files and keep them safe.

Article 6 (Safety)

  1. Users must check their health, fitness, and surroundings, and exercise at their own responsibility.
  2. Stop exercising immediately if pain, illness, or an abnormal condition occurs, and consult a doctor or other professional as needed.
  3. Minors must use the App with a parent or guardian’s consent and proper supervision. A parent or guardian’s consent is also required for purchases.

Article 7 (Prohibited Conduct)

Users must not:

  1. Violate laws, public order and morals, or a third party’s rights
  2. Use the App for an improper purpose
  3. Illegally copy, modify, analyze, redistribute, or sell all or part of the App, except where permitted by law
  4. Illegally circumvent or interfere with billing, trial periods, renewals, or other App Store, Google Play, or App mechanisms
  5. Cause damage or disadvantage to the Company or a third party
  6. Engage in any other conduct the Company reasonably considers inappropriate

Article 8 (Intellectual Property)

Copyrights, trademarks, and other intellectual property rights in the App and its bundled images, text, designs, programs, and other content belong to the Company or their rightful owners. Rights to records entered by users belong to those users.

Article 9 (Changes, Suspension, and Termination)

  1. The Company may change, suspend, or terminate all or part of the App when necessary for maintenance, incident response, compliance with laws or platform policies, or other reasons.
  2. For material changes or termination, the Company will endeavor to give advance notice by reasonable means, except in emergencies.
  3. Purchases when the service ends are handled under the procedures of the App Store or Google Play used for purchase and applicable law.
  4. Changes, suspension, or termination of rankings, a free additional feature, and related refunds or compensation are governed by Article 4-2(6) and (7). This Article governs the App and other features generally and does not extend ranking-specific treatment to paid features.

Article 10 (Warranties and Liability)

  1. The Company does not guarantee that the App is entirely free of defects, fit for a particular purpose, or that records will be kept permanently.
  2. Summaries, estimates, and other information shown in the App are for reference. The Company does not guarantee their accuracy, completeness, or medical validity.
  3. For damage caused by the Company’s ordinary negligence, the Company’s liability to a user who purchased a paid feature is limited to the total fees actually paid by that user for the App. There is no time limit based on the purchase date. This limit does not apply to users who made no purchase. It also does not apply to damage caused by the Company’s intentional or grossly negligent conduct, personal injury or death, or cases where liability cannot be limited under the Consumer Contract Act or other law.
  4. Matters for which the Company’s liability cannot be excluded or limited are governed by applicable law.

Article 11 (Changes to These Terms)

  1. The Company may change these Terms for changes in law, App features, or other reasonable grounds.
  2. For material changes, the Company will notify users of the changes and effective date on this page or by an appropriate method in the App.

Article 12 (Governing Law and Jurisdiction)

  1. These Terms are governed by the laws of Japan.
  2. Unless applicable law provides otherwise, the Tokyo District Court has exclusive agreed jurisdiction as the court of first instance for disputes concerning the App or these Terms.

SWITCHING PHONES

Switching phones

Normal records are stored on your phone. Only when you initiate Switching phones are your records encrypted and temporarily held to move them to your new phone. Once received, or after 24 hours, they can no longer be received and are deleted from regular storage (they may remain in maintenance backups for a limited time). They are not stored long-term or automatically updated.

  • Only when needed to verify eligibility to send records, store purchase information is checked on the server after your consent.
  • A hashed IP address is kept for approximately 10 minutes to prevent abusive high-volume access.
  • Transfer sizes and timestamps are kept for approximately 24 hours to enforce size and usage limits. These logs do not contain the contents of your workout records.

You can transfer workout records from Android to iPhone and from iPhone to Android. Moving records and restoring purchases are separate steps. Purchases cannot be restored across different stores.
