Terms of Service
Version 2026-08-12 · Updated August 12, 2026
Draft for review. This document was generated as a starting point and requires review by a licensed attorney before production use.
These terms govern your use of VO4. Please read them carefully — they include an assumption of risk and a limitation of our liability.
1. Acceptance of these terms
By tapping “I agree and accept the risks”, creating an account, or otherwise using the app, you agree to these Terms of Service and to our Privacy Policy. If you do not agree, do not use the app.
2. Eligibility
You must be at least 18 years old to use the app on your own. If you are between 13 and 17, you may use it only with the review and consent of a parent or legal guardian who agrees to these terms on your behalf. The app is not intended for children under 13.
3. Licence to use the app
We grant you a personal, revocable, non-exclusive, non-transferable licence to use the app for your own non-commercial training. You may not copy, resell, reverse engineer, scrape, or build a competing product from the app, its movement library, or its generated content.
4. Assumption of risk and release of liability
Physical exercise carries inherent risks, including muscle strain, joint injury, falls, cardiac events, and in rare cases serious injury or death. You voluntarily choose to perform the sessions, walks, holds and tests suggested by the app, and you assume all risk of injury or loss arising from them.
To the fullest extent permitted by law, you release and hold harmless VO4, its owners, employees and contractors from any claim, demand or cause of action arising out of your participation in any activity suggested by the app.
You are responsible for exercising in a safe environment, using equipment correctly, warming up, and scaling or skipping anything that does not feel safe on the day.
5. No medical advice
The app provides general fitness and educational information only. It is not medical advice, diagnosis or treatment, and it is not a substitute for care from a qualified professional. Consult a physician before starting any exercise program, particularly if you are pregnant, recovering from injury or surgery, or living with a cardiac, metabolic, respiratory, neurological or musculoskeletal condition.
Stop immediately and seek medical attention if you experience pain, dizziness, chest pressure, faintness or shortness of breath. Reporting “Something hurt” in the app adjusts your future programming — it is not a clinical assessment.
6. AI-generated content
Sessions, coach notes and chat replies are produced by AI models. Every generated session is checked by a deterministic validator against a fixed movement library and against the constraints you selected, and unsafe or unknown movements are swapped or replaced with a default plan. That validation reduces error but does not guarantee correctness, suitability or safety for you specifically.
AI output may be incomplete, inconsistent or wrong. Use your own judgement, and treat every suggestion as optional.
7. Your responsibilities
You agree to give accurate information about your constraints and preferences, to keep your account credentials secure, to use the app lawfully, and not to interfere with its operation or security. You are responsible for activity that occurs under your account.
8. Accounts and termination
You may use the app anonymously or create an account to sync across devices. You can delete your data at any time from the Profile tab. We may suspend or terminate access if you breach these terms or if we discontinue the service. Sections that by their nature should survive termination — including assumption of risk, limitation of liability and indemnification — continue to apply.
9. Limitation of liability
To the maximum extent permitted by law, the app is provided “as is” and “as available” without warranties of any kind. We are not liable for indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, lost data, or personal injury arising from your use of the app. Where liability cannot be excluded, our total aggregate liability is limited to the greater of the amount you paid us in the twelve months before the claim, or USD 50.
10. Indemnification
You agree to indemnify and hold harmless VO4 and its personnel from any claim, loss, liability, damage or expense (including reasonable legal fees) arising out of your use of the app, your breach of these terms, or your violation of any law or third-party right.
11. Governing law and disputes
These terms are governed by the laws of the State of [STATE], United States, without regard to conflict-of-law rules. The state and federal courts located in [COUNTY], [STATE] have exclusive jurisdiction over any dispute, and you consent to that venue.
12. Changes to these terms
We may update these terms. When the terms version changes, the app re-presents the consent gate on your next open with an “our terms have been updated” framing, and continued use after that point means you accept the updated terms.
