This English version is provided for reference only, as a courtesy translation of the original Japanese Terms of Service. In the event of any discrepancy or conflict between this translation and the Japanese original, the Japanese version shall prevail.
These Terms of Service (these "Terms") set forth the conditions for use of the iOS weight-tracking application "Fitona" (the "App") and all related services (collectively, the "Service") provided by the Fitona Development Team ("we," "us," or "our"). By downloading, installing, or using the Service, the user (the "User") is deemed to have agreed to all provisions of these Terms. If you do not agree to these Terms, do not download, install, or use the Service.
The User may use the Service only after reviewing and agreeing to these Terms and the Privacy Policy on the consent screen displayed when the App is launched for the first time. The Privacy Policy forms an integral part of these Terms.
In these Terms, the following terms have the meanings set forth below.
The Service provides features that allow the User to record body data such as weight and body fat percentage as well as Lifestyle Logs, and to review trends in graphs and a calendar. The main features of the Service are as follows.
The Service is provided free of charge; however, advertisements are displayed as set forth in Article 13, and paid features may be added in the future as set forth in Article 14. We may add, change, or remove all or part of the features of the Service without prior notice.
The Service is intended for persons who are at least 13 years of age (or, in countries or regions where a digital age of consent applies under data protection law, such as the EU, EEA, and the United Kingdom, at least that age (in principle 16, or between 13 and 16 depending on national law); or such higher minimum age as may otherwise be required by the laws of the country or region in which the User resides). Persons under such age may not use the Service.
If the User is a minor or otherwise has limited legal capacity, the User shall use the Service only with the consent of, and under the understanding and supervision of, a parent or other legal guardian. If a minor uses the Service, we will deem that the minor is using it with the consent of a legal guardian.
The Service operates only on iPhone and iPad devices provided by Apple that run a version of iOS/iPadOS supported by the App. The User shall, at their own expense and responsibility, prepare the devices, communication environment, and other items necessary to use the Service, and the User bears all costs necessary to use the Service, including internet connection fees, communication charges, and device costs. We do not guarantee operation on any particular device or environment, and all or part of the Service may become unavailable due to OS updates or similar events. The operating environment may change without notice for reasons such as feature improvements.
For the safe and proper provision of the Service, the correction of defects, the maintenance of security, and similar purposes, we may require the App to be updated to its latest version. On an App below a certain version designated by us, all or part of the Service may become unavailable, in which case the User must update the App to its latest version in order to continue using the Service. If the User does not perform such update, all or part of the App's features may become unavailable; except as provided in Article 18, we are not liable for any damage incurred by the User as a result.
Subject to the User's compliance with these Terms, we grant the User a limited, non-exclusive, non-transferable, non-sublicensable, and revocable right to use the App for private, non-commercial purposes on iOS devices that the User owns or controls.
The App is licensed, not sold, to the User. This license does not transfer to the User any rights in the App's source code, databases, features, design, or other components, and all rights not expressly granted in these Terms are reserved by us or by third parties holding legitimate rights.
The Service does not have an account registration system, and Record Data is stored only on the device used by the User. Record Data is not transmitted to or stored on any server managed by us.
The User acknowledges in advance that Record Data may be lost due to loss, malfunction, initialization, or replacement of the device, uninstallation of the App, or similar events. We assume no obligation or liability whatsoever for backing up or restoring Record Data. The User shall manage their data at their own responsibility, using integration with the Health App or standard iOS backup features (such as iCloud Backup) as necessary.
With the User's explicit permission, the Service can read weight and body fat percentage data from the Health App and write data recorded in the App to the Health App. The User may change or revoke this permission at any time via the iOS privacy settings.
If the User deletes a record in the App while Health integration is enabled, the weight and body fat percentage data that the App wrote to the Health App for that day may also be deleted. We are not liable for any data inconsistencies, conflicts with other apps, or duplication, omission, or loss of data arising from integration with the Health App.
The Service is not a medical device and is not intended for the diagnosis, treatment, or prevention of disease or any other medical purpose. Record Data, automatically calculated results such as BMI, graphs, and all other information displayed by the Service are provided as general reference information for personal health management; they are not a substitute for medical advice, diagnosis, or treatment, and their accuracy, completeness, or timeliness is not guaranteed.
The User shall always consult a physician or other qualified professional when making decisions regarding their health, diet, exercise, nutrition, or other health or medical matters, and shall not make such decisions based solely on information from the Service. If you have concerns about weight management, or if you have a history of eating disorders or similar conditions, please consult a professional before using the Service. We do not guarantee that use of the Service will result in improvement of your weight or health or any other health benefit.
In using the Service, the User shall not engage in any of the following acts.
All copyrights, trademarks, design rights, and other intellectual property rights relating to the App and the Service (including, without limitation, the app name, logo, icon, UI design, and program code) belong to us or to third parties holding legitimate rights. The license to use the Service under these Terms does not transfer or license any such intellectual property rights to the User. The name and logo "Fitona" are our identifying marks and may not be used without our permission.
Rights in the Record Data entered into the App by the User belong to the User.
If the User provides us with ideas, suggestions, improvement proposals, or other feedback regarding the Service ("Feedback"), we may freely use such Feedback without compensation to the User and without limitation as to duration, territory, or purpose (including for improving the Service and developing new features). The User agrees not to exercise moral rights against us with respect to Feedback and not to assert any other rights against us in relation to Feedback.
The Service displays advertisements through "Google AdMob," an advertising service provided by Google LLC ("Google"). Advertisements may be displayed at the bottom of screens throughout the App, on the save-confirmation screen, and in other locations within the App, and their placement, type, and volume may change without notice.
In connection with ad delivery, Google and its advertising network partners may collect and use information such as advertising identifiers. For details, please refer to the Privacy Policy and Google's applicable policies.
We do not review or guarantee the content of displayed advertisements in advance, and we assume no responsibility for third-party services or products provided through advertisements or for any transactions between the User and advertisers.
We may in the future add paid features to the Service, such as ad removal or additional functionality. The content, price, and purchase method of paid features will be available at the time of purchase through the App Store or displays within the App.
Purchases of paid features are made through Apple's In-App Purchase system, and payment, cancellation, and refunds are governed by the Apple Media Services Terms and Conditions and other conditions specified by Apple. We are not in a position to process refunds directly and do not independently guarantee refunds (except where refunds are required by the laws of the User's place of residence).
We may suspend or interrupt all or part of the Service without prior notice to the User in any of the following cases.
We may terminate the Service at our discretion with reasonable advance notice. Except as provided in Article 18, we are not liable for any damage incurred by the User due to the suspension, modification, or termination of the Service.
If we reasonably determine that the User has violated or is likely to violate these Terms, we may restrict or terminate the User's license to use the Service without prior notice.
If the User's agreement to these Terms terminates for any reason, the User shall cease using the App and delete it from their device. Articles 9, 11, 12, 17 through 19, 28, and 30 shall survive termination of the license.
The Service is provided on an "AS IS" and "AS AVAILABLE" basis. To the maximum extent permitted by law, we make no warranty, express or implied, that the Service will be fit for the User's particular purposes (including, without limitation, health management, dieting, or medical decision-making), that it will have the expected functionality, merchantability, accuracy, completeness, usefulness, or safety, that it will be free of defects, errors, or bugs, that defects will be corrected, that it will not infringe third-party rights, or that it will be continuously available.
We assume no responsibility for disputes arising between the User and any third party in connection with the Service.
Some countries and regions do not allow the exclusion of implied warranties by law. In such cases, the disclaimers in this Article apply only to the maximum extent permitted by applicable law, and nothing in this Article limits the statutory rights that the User holds as a consumer under mandatory provisions of law.
Except in cases attributable to our willful misconduct or gross negligence, we are not liable for any damage incurred by the User arising from the use of, or inability to use, the Service. We are also not liable for damage arising from third-party services (including Apple's App Store and Google's advertising services) or for damage arising from actions taken by the User on the basis of information displayed by the Service (including delays in consulting a medical institution).
Even where we are liable notwithstanding the preceding paragraph, our liability, regardless of the cause of action (whether breach of contract, tort, or otherwise), is limited to the amount actually paid by the User to us for the use of the Service that gave rise to the damage (or, if no payment has been made, JPY 1,000 or the equivalent in the User's local currency), and we are not liable for lost profits, loss of data, damage to reputation, costs of procuring substitute services, indirect damage, special damage, incidental damage, consequential damage, or punitive damages, even if we foresaw or could have foreseen the occurrence of such damage.
This Article does not apply to the extent restricted by the Consumer Contract Act of Japan or other mandatory provisions of law, nor to damage caused by our willful misconduct or gross negligence, nor to damage to life or body.
If we incur damage (including reasonable attorneys' fees) as a result of the User's violation of these Terms or infringement of a third party's rights in connection with the use of the Service, the User shall compensate us for such damage. If a third party makes a claim against us arising from the User's violation of these Terms, the User shall resolve such claim at their own responsibility and expense and shall hold us harmless.
The User represents and warrants that they do not currently fall under, and will not in the future fall under, the category of organized crime groups, members thereof, companies affiliated with such groups, corporate racketeers, or other anti-social forces. If it is found that the User has breached this representation, we may restrict or suspend the User's use of the Service without prior notice.
Because the App is distributed through the App Store, the User confirms and agrees to the following. This Article supplements the end-user license agreement (EULA) conditions required by Apple.
In using the App, the User shall comply with the export control laws and economic sanctions laws of Japan, the United States of America, and any other applicable country or region. The User represents and warrants that (i) they are not located in a country or region subject to a U.S. Government embargo, and (ii) they are not listed on any U.S. Government list of prohibited or restricted parties (including the U.S. Treasury Department's Specially Designated Nationals list and the U.S. Department of Commerce's Denied Persons List).
We may amend these Terms when we deem it necessary. Amended Terms take effect when posted on this website or displayed within the App. For amendments that materially affect the rights and obligations of the User, we will endeavor to provide advance notice within the App or on this website for a reasonable period. The date of last update is shown at the top of this page; please check it periodically.
If the User continues to use the Service after an amendment to these Terms, the User is deemed to have agreed to the amended Terms. Where the User's consent is legally required for a substantive amendment, we will separately obtain the User's consent by a method specified by us. If you do not agree to an amendment, please discontinue use of the Service.
Where we amend these Terms in material respects, we may display the amended Terms within the App and request the User's renewed agreement. In such case, if the User does not agree to the amended Terms, all or part of the Service will become unavailable. Notices regarding amendments and renewed agreement will be given by display within the App, or by such other method as we may specify.
Notices and communications between the User and us shall be made by the methods specified by us (such as the contact form on this website or postings on this website).
We may provide notices regarding maintenance information, amendments to these Terms, and other important matters relating to the Service by posting them within the App. Because important notices to the User may be given by this method, the User shall check the notices posted within the App from time to time. Such notices are deemed to have reached the User at the time they are displayed within the App.
The User may not assign or pledge as security their status under these Terms or their rights or obligations under these Terms to any third party without our prior written consent.
If we transfer the business related to the Service to a third party (whether by business transfer, corporate split, or otherwise), we may, in connection with such transfer, assign our status under these Terms, our rights and obligations under these Terms, and related information to the transferee, and the User hereby consents in advance to such assignment.
Even if any provision of these Terms or part thereof is determined to be invalid or unenforceable under applicable law, the remaining provisions of these Terms and the remaining portion of the provision determined to be invalid or unenforceable shall remain in full force and effect. Any provision determined to be invalid or unenforceable shall be deemed replaced by a valid provision that most closely reflects its intent to the maximum extent permitted by applicable law.
Our failure to enforce any provision of these Terms shall not be deemed a waiver of our rights under that provision.
These Terms and the Privacy Policy constitute the entire agreement between us and the User regarding the use of the Service, and supersede all prior oral or written agreements, representations, and understandings regarding the subject matter of these Terms.
The Japanese text of these Terms is the authoritative text. Even if translations into English or other languages are prepared for reference, only the Japanese text shall have effect, and in the event of any discrepancy between a translation and the Japanese text, the Japanese text shall prevail.
These Terms do not limit any rights that the User holds under mandatory consumer protection laws of the country or region in which the User resides.
The formation, validity, interpretation, and performance of these Terms are governed by the laws of Japan, without regard to conflict-of-law principles. However, if the User is a consumer residing outside Japan and mandatory provisions of the law of the User's place of residence afford the User protection, nothing in this Article deprives the User of such protection.
In the event of a dispute between us and the User in connection with the Service, the parties shall first attempt to resolve it through good-faith consultation; if the dispute cannot be resolved through consultation, the Tokyo District Court shall have exclusive jurisdiction as the court of first instance, except where the User is guaranteed the right to bring an action in the courts of their place of residence under the mandatory consumer protection laws described in the preceding Article.
Any matter not stipulated in these Terms, or any doubt regarding the interpretation of these Terms, shall be resolved through good-faith consultation between us and the User.
