Terms of Service
These Terms of Service (the "Terms") set out the conditions for using LiFTY (the "App") and the rights and obligations between the operator and users. By using the App, users are deemed to have agreed to these Terms.
Article 1 (Operator)
The App is provided by Ippei Ishida (the "Operator").
Contact: contact@liftyfit.com
Article 2 (Application)
These Terms apply to all relationships between the Operator and users in connection with the use of the App.
Article 3 (Registration and Anonymous Use)
1. The App can be used anonymously, without account registration. Data recorded during anonymous use is stored only on the user's device.
2. Users may optionally sign in using an email address, Apple ID, or Google account. Signing in is intended to enable cloud backup of recorded data and restoration when switching devices.
3. Users shall keep their registration information accurate and up to date.
Article 4 (Handling of Recorded Data)
1. Recorded data in the App (training logs, body measurements, etc.) is, by default, stored only in a local database on the user's device.
2. Only when a user is signed in and subscribed to a paid plan is recorded data also backed up and synced to a cloud service commissioned by the Operator. If a user remains on the free plan while signed in, no cloud sync takes place.
3. Details of data handling are set out separately in the Privacy Policy.
Article 5 (Paid Plans and Payment)
1. In addition to the free plan, the App offers a paid plan (monthly or annual) that provides additional features (cloud sync, higher limits on custom exercises/locations, ad removal, etc.).
2. Purchases of the paid plan are made through the App Store or Google Play, and payment is processed by the payment systems provided by Apple Inc. or Google LLC. Price, billing cycle, and auto-renewal terms are as displayed by each store at the time of purchase.
3. Cancellation of the paid plan must be done through the subscription management screen of the relevant store. The Operator does not provide a cancellation method within the App.
4. Deleting your account and canceling a paid plan subscription are separate procedures. Deleting your account from Settings does not automatically cancel a paid plan subscription; billing may continue unless you separately complete the cancellation process.
Article 6 (Prohibited Conduct)
Users shall not engage in any of the following when using the App.
(1) Acts that violate laws, regulations, or public order and morals
(2) Acts that infringe the intellectual property rights, privacy, or other rights of the Operator, other users, or third parties
(3) Acts that place an excessive load on the App's servers or network, or that interfere with the operation of the App
(4) Reverse engineering, decompiling, disassembling, or otherwise analyzing the App's source code (except where permitted by law)
(5) Unauthorized access or attempts thereof
(6) Any other conduct that the Operator deems inappropriate
Article 7 (Suspension, Modification, and Termination of the Service)
1. The Operator may temporarily suspend the provision of the App without prior notice to users in the event of system maintenance, natural disaster, or other unavoidable circumstances.
2. The Operator may, after providing prior notice, change the content of the App or discontinue its provision. The Operator shall not be liable for any damages incurred by users as a result of discontinuation of the App.
Article 8 (Disclaimer of Warranties)
1. The App is intended for managing training records and does not provide medical advice, diagnosis, or treatment. Users are responsible for their own training decisions and outcomes.
2. The Operator makes no express or implied warranty that the App is free of defects, whether factual or legal, including defects related to safety, reliability, accuracy, completeness, effectiveness, or fitness for a particular purpose.
3. Except in cases of the Operator's willful misconduct or gross negligence, the Operator shall not be liable for any damages incurred by users arising from the App.
Article 9 (Limitation of Liability)
Notwithstanding the proviso to the preceding Article, the Operator's liability for damages shall be limited to the amount paid by the user to the Operator for the paid plan during the preceding 12 months (to the extent this does not conflict with the Consumer Contract Act or other mandatory laws).
Article 10 (Changes to These Terms)
The Operator may modify these Terms without prior notice to or consent from users whenever the Operator deems it necessary. Revised Terms take effect once displayed within the App or on the App's official website.
Article 11 (Governing Law and Jurisdiction)
These Terms shall be governed by the laws of Japan. Any dispute arising in connection with the App shall be subject to the exclusive jurisdiction of the court having jurisdiction over the location of the Operator as the court of first instance.
