Terms of Service

Effective date: October 21, 2026
Last updated: October 21, 2026

These Terms of Service (the "Terms") are a legal agreement between you and SparkFast Technologies LLC, a Florida limited liability company ("SparkFast", "we", "us" or "our"). They govern your use of the SparkFast mobile application (the "App"), our website at www.sparkfast.app and its subdomains (the "Website"), and any related features, content and services we provide (together, the "Services").

By creating an account, starting a free trial, purchasing a subscription or otherwise using the Services, you agree to these Terms and to our Privacy Policy, which explains how we collect and use your personal data. If you do not agree, do not use the Services.

Please read Section 16 (Disputes) carefully. It affects how disputes between you and SparkFast are resolved.

1. Important health and medical disclaimer

SparkFast is not a medical service, is not a medical device, and does not provide medical advice, diagnosis or treatment. All content in the Services, including fasting timers, fasting plans and protocols, the SPARK Chart, refeed protocols, challenges, articles, research summaries, notifications, and messages written by our companion feature, is provided for general informational and educational purposes only.

• Talk to your doctor first. Consult a physician or other qualified healthcare provider before you start fasting, change your diet, or change any fasting or eating pattern, and whenever you have questions about a medical condition.
• Fasting is not right for everyone. Do not use the Services to fast without medical supervision if you are pregnant, trying to become pregnant or breastfeeding; are under 18; have, or have had, an eating disorder; have diabetes or take medication that lowers blood sugar or blood pressure; are underweight; or have any other medical condition that fasting could affect.
• Stop and seek help. Stop fasting and seek medical attention if you feel faint, dizzy, confused, unwell or otherwise unsafe. In an emergency, call 911 or your local emergency number. The Services are not monitored for emergencies.
• Estimates, not measurements. The SPARK Chart, metabolic phase indicators and similar features show estimates based on general population averages. They do not measure your own biology, and your results will vary.
• Never delay care. Never ignore professional medical advice, or delay seeking it, because of something you read or saw in the Services.

You use the Services, and make decisions about your health, at your own risk and judgment.

2. No practitioner affiliation or endorsement

The Services may mention or cite researchers, physicians and other practitioners, and may link to published research. These references are for education only. Unless we expressly say otherwise, SparkFast is not affiliated with, endorsed by or sponsored by any person, institution or study we mention, and none of them has reviewed or approved the Services. Mention of a study does not mean its authors or their institutions endorse SparkFast.

3. Eligibility and accounts

• Age. You must be at least 18 years old to use the Services.
• Your account. To use the App you must create an account, using an email address and password, or a supported sign-in provider such as Apple or Google. You agree to give accurate information and to keep it up to date.
• Security. You are responsible for keeping your login details confidential and for all activity under your account. Tell us promptly at support@sparkfast.app if you believe your account has been used without your permission.
• One person per account. Accounts are personal. Do not share your account or let anyone else use it.

4. Subscriptions, free trials and payments

• Subscription service. Most features of the App require an active paid subscription. We may offer monthly, annual or other plans. The prices, features and any free-trial period are shown in the App before you buy.
• Purchases through the app stores. Subscriptions are sold and billed by Apple (App Store) or Google (Google Play), not by SparkFast. Payment is charged to your app-store account when you confirm the purchase, or when any free trial ends. The store's own terms also apply to your purchase.
• Automatic renewal. Your subscription renews automatically at the end of each billing period, at the then-current price, unless you cancel at least 24 hours before the period ends. You can manage or cancel your subscription at any time in your Apple ID or Google Play account settings. Deleting the App or your SparkFast account does not cancel a subscription. You must cancel through the store.
• Free trials. If we offer a free trial, it converts to a paid subscription automatically when it ends, unless you cancel at least 24 hours before it ends. Trials are limited to one per person unless we say otherwise.
• Cancellation. If you cancel, you keep access until the end of the period you have already paid for. Then your subscription ends.
• Refunds. Because Apple and Google process all payments, refund requests must be made to them under their refund policies. Apple: reportaproblem.apple.com. Google: through your Google Play account. Except where the law requires otherwise, fees already paid are not refundable for partial periods.
• Price changes. We may change subscription prices. The app store will notify you in advance as its rules require, and where required will ask for your consent before a higher price applies. If you do not agree to a price change, you may cancel before it takes effect.
• Restoring purchases. If you change devices, use "Restore Purchases" in the App to restore an active subscription linked to the same app-store account.
• Access through a coach or promotion. A coach, partner or promotion may give you free or discounted access for a limited time. When that access ends, continued use requires a paid subscription, as described above. We never charge you without your purchase through an app store.

5. Your content and your data

• Your content. You may enter or upload information such as fasting records, weight, measurements, glucose and ketone readings, sleep and activity data, notes and progress photos ("Your Content"). You keep all ownership of Your Content.
• Permission you give us. You give us a non-exclusive, worldwide, royalty-free licence to host, store, copy, process and display Your Content only as needed to operate and provide the Services to you, including to generate your charts, plans and personalised messages, and to share it with people you choose to share it with (see Section 7). This licence ends when Your Content is deleted from our systems, apart from backup copies that are deleted in the normal course.
• We do not sell your health data. How we collect, use, protect and share your personal data, including health data, is described in our Privacy Policy.
• Your responsibility. You are responsible for Your Content. Do not upload content that is unlawful, that infringes anyone's rights, or that shows another person without their permission.

6. Connected health services and devices

The App can connect, at your choice, to third-party services such as Apple Health, Google Health Connect and supported measurement devices. When you connect one:

• you authorise us to read, and where you permit, write the data types you approve, which you can withdraw at any time in your device or service settings;
• the accuracy of that data depends on the third-party service and device, and we are not responsible for errors in it; and
• your use of that service is governed by its own terms and privacy policy.

7. Coaches and sharing

• Coaches are independent. Coaches, nutritionists, trainers and other professionals who use SparkFast (each a "Coach") are independent third parties. They are not employees, agents or partners of SparkFast. We do not supervise, verify the credentials of, or take responsibility for the advice or services a Coach provides. Your relationship with a Coach is between you and that Coach.
• You control sharing. You decide whether to share any of your data with a Coach, which types of data, and for how long. You can stop sharing at any time in the App.
• Commissions. A Coach who invited you may receive a referral commission if you subscribe to SparkFast. This never affects the price you pay.
• Separate terms. Coaches, ambassadors and other referral partners must also accept the separate partner terms we provide to them.

8. AI-generated content

Some content in the Services, such as your personalised fasting plan, is created with the help of artificial-intelligence tools provided by third parties. AI-generated content may be inaccurate, incomplete or unsuitable for your situation. It is subject to Section 1 and is not medical advice. Do not rely on it as the sole basis for a decision about your health.

9. Acceptable use

You agree not to:

• use the Services for any unlawful purpose, or in breach of these Terms;
• copy, modify, distribute, sell or lease any part of the Services, or reverse-engineer, decompile or try to extract the source code of the App, except where the law expressly permits it;
• access the Services by automated means (bots, scrapers, crawlers) or interfere with, overload or disrupt the Services or their security;
• access another user's account or data without permission, or impersonate any person;
• manipulate challenges, leaderboards, referral programs or promotions, including by creating multiple or fake accounts; or
• post or share content that is abusive, harassing, hateful, sexually explicit, misleading, or that promotes disordered eating or self-harm.

10. Intellectual property

The Services and all their content, features and technology, including the SparkFast name and logo, the SPARK Chart, software, text, graphics, articles and design, are owned by SparkFast Technologies LLC or its licensors and are protected by copyright, trademark and other laws. Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, and the Website, for your own personal, non-commercial use. All rights not expressly granted are reserved.

Feedback. If you send us ideas or suggestions, we may use them freely without any obligation to you.

11. Third-party services and links

The Services may contain links to, or integrations with, websites and services we do not own or control, such as app stores, sign-in providers and research publications. We are not responsible for their content, policies or practices, and your use of them is at your own risk.

12. Changes to the Services and to these Terms

We may change, add or remove features of the Services at any time. We may update these Terms from time to time. If we make a material change, we will notify you through the App, by email or by another reasonable method before the change takes effect, and we will update the "Last updated" date above. If you continue to use the Services after the change takes effect, you accept the updated Terms. If you do not agree, stop using the Services and cancel your subscription.

13. Suspension, termination and account deletion

• By you. You may stop using the Services at any time, and you may delete your account in the App's settings or by following the instructions at www.sparkfast.app/account-deletion. Deleting your account permanently erases your data as described in our Privacy Policy and cannot be undone. Remember to cancel your subscription separately through the app store.
• By us. We may suspend or end your access if you materially breach these Terms, if required by law, or if your use creates risk or legal exposure for us or other users. Where reasonable, we will tell you first and give you a chance to fix the problem. If we end the Services for reasons other than your breach, we will tell you how to request a pro-rata refund through the app store where applicable.
• What continues. Sections 1, 2, 5 (your responsibility), 10, and 14 to 19 continue after these Terms end.

14. Disclaimer of warranties

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE OR SECURE, OR THAT ANY HEALTH, WEIGHT OR OTHER RESULT WILL BE ACHIEVED.

15. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW:

(a) SPARKFAST AND ITS MEMBERS, MANAGERS, EMPLOYEES AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS OR GOODWILL, ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS; AND

(b) OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS WILL NOT EXCEED THE GREATER OF (i) THE AMOUNT YOU PAID FOR THE SERVICES IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (ii) ONE HUNDRED U.S. DOLLARS (US$100).

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by our negligence, or for fraud or gross negligence.

16. Disputes, governing law and venue

• Governing law. These Terms and any dispute arising out of or relating to them or the Services are governed by the laws of the State of Florida, United States, and applicable U.S. federal law, without regard to conflict-of-law rules.
• Talk to us first. Before filing any claim, you agree to contact us at support@sparkfast.app with a description of the issue, and we agree to try in good faith to resolve it informally within 60 days.
• Courts. If we cannot resolve a dispute informally, it must be brought exclusively in the state courts located in Pinellas County, Florida, or the U.S. District Court for the Middle District of Florida, and you and we consent to the personal jurisdiction of those courts. Either of us may instead bring an individual claim in small-claims court if it qualifies.
• Individual claims only. To the fullest extent permitted by law, you and we each agree to bring claims only in an individual capacity, and not as a plaintiff or class member in any class, collective or representative action.
• Consumers outside the United States. If you live in the United Kingdom, the European Union or another country whose laws give consumers mandatory rights, nothing in these Terms takes away those rights. This includes any right to bring proceedings in the courts of the country where you live and the protection of that country's mandatory consumer laws.

17. Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless SparkFast and its members, managers, employees and agents from claims, losses and expenses, including reasonable legal fees, arising from your breach of these Terms, your misuse of the Services, or Your Content. This section does not apply to consumers where local law does not allow it.

18. App store terms

If you downloaded the App from the Apple App Store or Google Play:

• These Terms are between you and SparkFast only, not with Apple or Google. SparkFast, not Apple or Google, is solely responsible for the App and its content.
• Apple and Google have no obligation to provide maintenance or support for the App.
• If the App fails to meet any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation for the App.
• SparkFast, not Apple or Google, is responsible for addressing any claims by you or a third party relating to the App, including product-liability claims, claims that the App fails to meet legal or regulatory requirements, consumer-protection or privacy claims, and claims that the App infringes a third party's intellectual property.
• You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
• Your use of the App must also comply with the store's own usage rules.

19. General

• Entire agreement. These Terms, together with our Privacy Policy and any terms shown to you at purchase, are the entire agreement between you and us about the Services.
• Severability. If any part of these Terms is found unenforceable, the rest remains in effect, and the unenforceable part will be enforced to the maximum extent permitted.
• No waiver. If we do not enforce a right, we have not given it up.
• Assignment. You may not transfer your rights under these Terms. We may transfer ours in connection with a merger, acquisition or sale of assets, or to an affiliate, with notice to you where required by law.
• Events beyond our control. We are not responsible for delays or failures caused by events beyond our reasonable control.
• Notices. We may send you notices through the App or to the email address on your account.
• Language. If we provide a translation of these Terms, the English version controls to the extent permitted by law.
