FastLite
Contents
These Terms of Use (the "Terms") are a legally binding agreement between you and xuyongfang ("we," "us," or the "Developer") governing your use of the FastLite iOS application, including its home-screen widgets and Apple Watch app (collectively, the "App").
By downloading, installing, launching, or otherwise using the App, you confirm that you have read these Terms in full, understand them, and accept all of them without reservation, including the health disclaimer in Section 5, the disclaimer of warranties in Section 12, the limitation of liability in Section 13, and the indemnification provisions in Section 14. These provisions may limit or exclude our liability to you, so please read them carefully.
If you do not agree with any part of these Terms, stop using the App immediately and delete it from your device.
If you are under 18 years of age or otherwise lack full legal capacity under the laws of your jurisdiction, you must read these Terms together with a parent or legal guardian and may use the App only with their consent.
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the App on Apple devices that you own or control, for personal, non-commercial purposes only.
This license is not a sale of the App. We reserve all rights not expressly granted to you in these Terms.
You may not:
The App is purely a tracking and timing tool. Its features include a fasting timer, fasting plan management, weight and water logging, statistics, local reminders, home-screen widgets, and an Apple Watch app.
The App has no account system. All data is stored locally on your device, as described in our Privacy Policy.
You understand and agree that the App is a tool, not a health service, medical service, or nutritional consulting service of any kind. We are not a medical institution, and we are not your physician, dietitian, or health advisor. No physician-patient or professional advisory relationship is formed between you and us as a result of your use of the App.
This is the most important section of these Terms. Please read it in full.
The App is not a medical device and has not been registered, filed, or certified with any national or regional drug or medical device regulatory authority. The App is not intended for the diagnosis, treatment, alleviation, or prevention of any disease, or for the monitoring of any health condition.
All content presented in the App, including but not limited to descriptions of fasting stages, descriptions of bodily responses, dietary suggestions, plan recommendations, motivational and reminder messages, statistical charts, and their interpretation, is general information compiled from publicly available educational sources, is provided for reference only, and does not constitute and should not be treated as medical advice, a diagnosis, a treatment plan, or a nutritional prescription. It is no substitute for an in-person evaluation and professional opinion from a licensed physician, registered dietitian, or other qualified healthcare professional.
We make no warranty as to the accuracy, completeness, timeliness, or suitability of such content for your individual circumstances. Nutritional and metabolic science continues to evolve, and different studies may reach conflicting conclusions.
The so-called "body stages" displayed in the App (for example, glycogen depletion, fat burning, ketone production, and cellular autophagy) are derived entirely from the elapsed duration of your fast and are not in any way an actual measurement, test, or diagnosis of your physical condition. The App does not have, and does not claim to have, any capability to monitor physiological indicators.
Individual metabolic rates, body composition, activity levels, prior diet, and health status vary enormously, and your actual physiological response may bear no resemblance to the stages shown in the App. Do not rely on them to assess your own health.
The reminders, celebrations, streak encouragement, and similar messages in the App are product design elements intended to help you maintain a tracking habit. They do not constitute advice, a requirement, or pressure to continue fasting. In all circumstances, how your body feels should take priority over any prompt in the App. You can turn off all reminders in the App at any time.
Intermittent fasting may carry risks, including but not limited to hypoglycemia, dizziness, fatigue, reduced concentration, dehydration, electrolyte imbalance, gastrointestinal discomfort, sleep disturbances, menstrual irregularities, the onset or worsening of eating disorders, and interference with the effectiveness of medications.
You alone decide whether to begin fasting, which protocol to follow, and for how long, and you alone bear all resulting health risks and consequences. We strongly recommend that you consult a physician before starting any fasting plan, particularly if you fall into any of the groups listed in Section 6.
If during a fast you experience dizziness, palpitations, cold sweats, blurred vision, extreme weakness, confusion, or any other significant discomfort, stop fasting and eat immediately, and seek medical attention or call emergency services if necessary. Do not keep going simply because you "want to finish this round." No progress indicator, streak count, or achievement in the App is worth maintaining at the expense of your health.
The App cannot recognize emergencies or call for help, and it cannot raise an alarm or notify anyone if you are in danger.
To the fullest extent permitted by law, we accept no liability for any physical discomfort, harm to your health, worsening of any illness, disability, or death resulting from your use of the App, from fasting, or from any health decision you make in reliance on any content in the App.
If any of the following applies to you, do not use the App to fast without the express approval of your physician:
The App cannot and will not verify whether you belong to any of these groups. You are responsible for honestly assessing your own condition and making a prudent decision.
All data in the App is stored only on your device. We do not provide cloud backup, cross-device sync, or account recovery.
You understand and accept that if your device is lost, damaged, or stolen, is reset to factory settings, experiences a failed system update, or if you accidentally delete the App or uninstall and reinstall it, all data in the App will be permanently and irretrievably lost. We do not hold any copy of your data and therefore cannot recover it for you. Please keep your own backups through iCloud or your computer.
We accept no liability for any loss arising from lost data.
The App's basic fasting timer is free to use. Membership unlocks full statistics, all fasting plans, weight and water logging, and other features.
| Plan | Price | Billing Period | Auto-Renewal |
|---|---|---|---|
| Lifetime Membership | As shown in the App Store | One-time purchase | No |
| Annual Membership | As shown in the App Store | Every 12 months | Yes (includes a 7-day free trial) |
The amount you are charged is the amount displayed on the App Store checkout page and may vary by region, exchange rate, taxes, or promotions. We reserve the right to adjust future pricing; price changes do not affect purchases already completed, and any change to a subscription price will be communicated to you in advance, and your consent obtained, in accordance with Apple's rules.
We may add, adjust, or remove specific features included in Membership. If the removal of a feature would materially diminish the value of Membership, we will notify you in the App in advance. A Lifetime Membership remains valid for as long as the App continues to exist; it is not a commitment that the App will operate indefinitely.
All transactions for the App are processed and settled by the Apple App Store. We have no authority to accept or issue refunds directly.
To request a refund, apply directly to Apple through reportaproblem.apple.com in accordance with Apple's applicable policies. Whether a refund is granted is decided independently by Apple under its own policies; we cannot intervene in, expedite, or guarantee any outcome.
All copyrights, trademarks, and other intellectual property rights in the App and all of its content, including but not limited to interface design, visual guidelines, illustrations and mascot artwork, icon system, copy, program code, data structures, and interaction flows, belong to the Developer and are protected by the Copyright Law of the People's Republic of China and applicable international treaties.
Without our prior written permission, you may not copy, modify, distribute, display, publish, or commercially exploit any of it in any form. Your use of the App does not transfer or grant you any of these rights.
To the fullest extent permitted by law, the App and all of its content are provided "AS IS" and "AS AVAILABLE," and we make no warranties of any kind, whether express or implied.
In particular, we disclaim any warranty (including but not limited to) that:
You understand that notification delivery depends on iOS system scheduling and may be delayed or fail to fire because of Low Power Mode, Focus modes, system restrictions, device restarts, or similar causes; widget and watch data refreshes are likewise subject to system scheduling. You should not rely on the App as your sole or critical means of being reminded of the time.
Some jurisdictions do not allow the exclusion of implied warranties, in which case the above exclusions apply in those jurisdictions to the maximum extent permitted by law.
To the fullest extent permitted by law, and regardless of whether the claim is based on contract, tort (including negligence), strict liability, or any other legal theory, we shall not be liable for any of the following, even if we have been advised of the possibility of such losses:
In no event shall our total aggregate liability to you under these Terms and in connection with the App exceed the amount you actually paid to us for the App during the twelve (12) months preceding the date on which you assert your claim; if you have never paid, our maximum liability is zero.
Some jurisdictions do not allow the exclusion or limitation of liability for incidental or consequential damages, in which case the above limitations apply in those jurisdictions to the maximum extent permitted by law. Nothing in this Section excludes liability that cannot be excluded by law (such as liability for personal injury caused by willful misconduct or gross negligence).
You agree that if any third party brings a claim, demand, lawsuit, or administrative penalty against us as a result of your breach of these Terms, your violation of any applicable law, or your improper use of the App, you will compensate us for all resulting losses, including but not limited to damages, fines, and reasonable attorneys' fees, court costs, and investigation expenses, and will hold us harmless.
The App relies on several system services provided by Apple, including App Store in-app purchases, HealthKit, local notification scheduling, WidgetKit, and WatchConnectivity. These services are provided and controlled independently by Apple.
We accept no liability for the availability, accuracy, or security of third-party services or for changes to their policies, and we cannot guarantee their continued availability. Your use of third-party services is governed by their respective terms and policies.
You acknowledge that Apple is not a party to these Terms and bears no responsibility for the App, and that any claim arising from the App should be directed to us rather than to Apple. Apple and its subsidiaries are third-party beneficiaries of these Terms and have the right to enforce them against you.
We reserve the right, at our sole discretion, to update, modify, suspend, or permanently discontinue the App or any of its features at any time, without prior notice and without liability to you or any third party. If we decide to discontinue the App permanently, we will make reasonable efforts to notify you in advance.
If you breach these Terms, we may terminate the license granted to you immediately. You may terminate these Terms at any time by deleting the App.
Sections 11 through 14 and Section 20 survive termination of these Terms.
We shall not be liable if the App cannot be provided normally or these Terms cannot be performed because of events beyond our reasonable control, including natural disasters, epidemics, war, government action, changes in laws or regulations, telecommunications or network failures, changes to Apple platform policies, or hacking attacks.
If any provision of these Terms is held by a competent authority to be invalid, unlawful, or unenforceable, that provision shall be modified or severed to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
Our failure to exercise, or delay in exercising, any right under these Terms does not constitute a waiver of that right, and no single or partial exercise of any right precludes the further exercise of that right or of any other right.
These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the App and supersede all prior oral or written communications and understandings.
You may not assign any of your rights or obligations under these Terms without our prior written consent. We may assign these Terms in connection with a transfer of business, merger, or acquisition.
The formation, validity, interpretation, and performance of these Terms, and the resolution of any dispute arising from them, are governed by the laws of the People's Republic of China (for the purposes of this Section, excluding the laws of the Hong Kong Special Administrative Region, the Macao Special Administrative Region, and the Taiwan region).
Any dispute arising out of or in connection with these Terms shall first be resolved through good-faith negotiation. If negotiation fails, either party may bring an action before the competent People's Court in the place where the Developer is domiciled.
If mandatory consumer protection laws in your jurisdiction grant you rights or remedies that cannot be excluded by agreement, nothing in this Section affects those rights.
We may revise these Terms in response to feature changes, legal requirements, or operational needs, and will update the "Last updated" date at the top of this page accordingly. For material changes, we will provide a prominent notice in the App.
Your continued use of the App after a change takes effect constitutes acceptance of the revised Terms. If you do not accept them, stop using the App and delete it.
These Terms are written in Simplified Chinese. Any translation into another language is provided for convenience only; in the event of any discrepancy between a translation and the Simplified Chinese version, the Simplified Chinese version prevails.
