These Terms of Use (the "Terms") govern your use of the mobile application "Diet Tracker" (the "App") provided by Yomoe Studio ("we", "us", or "our"). By downloading or using the App, you agree to be bound by these Terms.
1. About the App
The App is a personal tracking tool that lets you record your weight, meals, exercise, water intake, body measurements, menstrual cycle, and bowel movements, and view summaries and charts of those records. The App is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or condition.
2. Health and Medical Disclaimer
2.1 Values shown by the App — including BMI, basal metabolic rate, recommended intake, goal projections, and estimated menstrual and ovulation dates — are reference figures calculated from general formulas and the data you enter. They are not medical diagnoses, advice, or instructions.
2.2 The menstrual cycle and ovulation estimates must not be used for contraception, family planning, or any other medical purpose. We accept no responsibility for any outcome arising from such use.
2.3 Consider your own state of health before changing your diet, restricting food intake, or beginning exercise. If you have a medical condition, are pregnant or breastfeeding, are a minor, or have any concerns about your health, consult a physician or other qualified professional before using the App.
2.4 We are not liable for any health consequences arising from your use of the App or from actions taken in reliance on information displayed by it.
3. Eligibility
3.1 You agree to use the App in compliance with these Terms and all applicable laws.
3.2 Minors may use the App only with the consent of a parent or guardian. The App is not directed to children under 13.
4. Prohibited Conduct
You may not:
(a) copy, modify, disassemble, decompile, or reverse engineer the App;
(b) redistribute, sell, lease, or publicly transmit the App or any part of it;
(c) circumvent or disable the advertising or in-app purchase functions of the App;
(d) place an excessive load on, or attempt to gain unauthorized access to, our servers or networks;
(e) engage in any conduct that violates applicable law or public order, or that we reasonably consider inappropriate.
5. Your Data and Responsibility
5.1 The data you record in the App is stored only on your device. We do not hold, manage, or have the ability to restore it.
5.2 We are not responsible for recovering data lost due to loss, damage, reset, or replacement of your device, uninstallation of the App, or defects in the App or the operating system.
5.3 We recommend that you use the App's backup function regularly. Storing and sharing backup files is your responsibility.
6. Advertising
6.1 The App displays advertisements so that it can be offered free of charge.
6.2 Advertisements are served by third-party advertising networks. We do not endorse and make no warranty as to the accuracy, legality, or safety of any advertisement, advertised product or service, or linked destination. Any transaction with an advertiser is solely between you and that advertiser.
6.3 Information handling relating to advertising is described in our Privacy Policy.
7. In-App Purchases
7.1 The App offers a paid version (the "Pro" version), which includes the following:
(a) removal of in-app advertisements;
(b) access to the full history on the Statistics screen (the free version is limited to the most recent three months);
(c) all eight theme colors (the free version includes two).
7.2 Purchases, billing, and refunds are handled by the Apple App Store or Google Play under their respective terms. We do not process payments and are not in a position to grant refunds. Refund requests must be submitted through the applicable store.
7.3 Purchased features can be restored using the same Apple ID or Google account used for the original purchase. Purchases cannot be transferred between accounts or between platforms.
7.4 If your purchase status is lost after a device change or data erase, use the "restore purchases" function within the App.
8. Changes, Suspension, and Termination
8.1 We may change, add to, remove, suspend, or discontinue the App or any of its features.
8.2 The foregoing includes changes to which features are available in the free version and which require Pro. We do not guarantee that the set of features available in the free version, or that the App will continue to be offered free of charge, will remain unchanged.
8.3 For changes that materially affect users, we will give notice within the App, or by other appropriate means, a reasonable period before the change takes effect. This does not apply to urgent maintenance, security measures, or changes required by law.
8.4 Notwithstanding the foregoing, for users who have already purchased the Pro version, we will not make chargeable, or otherwise restrict, any feature that was included at the time of their purchase.
8.5 We are not liable for any loss arising from actions taken under this Section, except where we act in breach of Section 8.4.
9. Intellectual Property
All copyrights, trademarks, and other intellectual property rights in the App belong to us or our licensors. These Terms grant you a limited, non-exclusive, non-transferable right to use the App in accordance with these Terms, and do not transfer any intellectual property rights to you. You retain all rights to the data you record in the App.
10. Disclaimer of Warranties and Limitation of Liability
10.1 The App is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including completeness, accuracy, usefulness, fitness for a particular purpose, and uninterrupted or error-free operation.
10.2 Except in cases of our willful misconduct or gross negligence, we are not liable for any damages arising from your use of, or inability to use, the App.
10.3 Where we are found liable, our total liability shall not exceed the amount you have paid to us in connection with the App.
10.4 Nothing in these Terms limits liability that cannot be limited under applicable mandatory consumer protection law.
11. Changes to These Terms
We may revise these Terms as needed. Revised Terms take effect when posted in the App or on the app store listing, and your continued use of the App after that time constitutes acceptance of the revised Terms.
12. Language
12.1 These Terms are written in Japanese, and the Japanese version is the original and controlling text.
12.2 Translations into English and other languages are provided for convenience only. In the event of any inconsistency or difference in interpretation between the Japanese version and any translation, the Japanese version prevails.
12.3 The preceding provisions apply equally to the Privacy Policy and any other document we provide in connection with the App.
13. Governing Law and Jurisdiction
These Terms are governed by the laws of Japan. Any dispute arising in connection with the App shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
