Terms of Service

1. Acceptance of These Terms

These Terms of Service (the "Terms") form a legally binding agreement between you ("you" or "User") and SILVERDRAGON TECH PTE. LTD. ("SILVERDRAGON", "we", "our", or "us"), the operator of vitalbay, governing your access to and use of the vitalbay application, its Apple Watch companion app, and related services (collectively, the "Service"). vitalbay is an AI strength-training companion app for iPhone and Apple Watch. It provides training plans and records (exercises, sets, reps, weight, duration), pre-recorded coaching audio played back during a workout, a map-style training journey, body-metric tracking, and an Apple Watch companion that records heart rate during a workout session.

By signing in with Apple or Google, or otherwise accessing or using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which forms part of your agreement with us. Unless these Terms expressly provide otherwise, any new feature that adds to or enhances the current Service is also subject to these Terms.

If you do not agree to these Terms or to a later change to them, you must not use the Service, and you must stop using it.

2. Eligibility

The Service is intended for adults and is not directed to children. We do not knowingly create accounts for, or collect information from, children. By using the Service you confirm that you are old enough under the law that applies to you to enter into a binding agreement and to consent to the processing of your information. If you are a minor in your jurisdiction, you may use the Service only with the consent and active supervision of a parent or legal guardian, who accepts these Terms on your behalf and remains responsible for your use of the Service; a minor should perform strength training only under the supervision of a guardian or a qualified professional.

If we learn that we have collected information from a child without the required consent, we will delete it. If you believe a child has provided us with information, contact us at 3rd@silverdragonltd.com. We may decline to provide the Service to any user at our discretion where required by law.

3. Accounts and Security

You access the Service by signing in with Apple or with Google; vitalbay does not offer password-based accounts. Your vitalbay account is created through the identity provider you choose, and we receive the account identifier that provider returns, your email address (which may be a private relay address if you use Apple's "Hide My Email" option), and, where you provide them, a display name and an avatar. Safeguarding the third-party account you sign in with is your responsibility.

You agree to keep your profile information accurate, and to promptly notify us of any unauthorized access to your account. You are responsible for all activity that occurs under your account, and you may not sell, transfer, or lend it. We may suspend or disable access that we reasonably believe has been compromised or used in violation of these Terms. Your use of Sign in with Apple or Google Sign-In is also governed by that provider's own terms; if you lose access to your Apple or Google account, you may lose access to your vitalbay account and its data.

4. License to Use the Service

Subject to your compliance with these Terms, SILVERDRAGON grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable license to access and use the Service for your personal, non-commercial fitness and training purposes. All rights not expressly granted are reserved.

5. Acceptable Use

You agree not to, and not to permit any third party to:

6. Health and Fitness Disclaimer

vitalbay is a general fitness and wellness product. It is not a medical device. It does not diagnose, treat, cure, mitigate, or prevent any disease or medical condition, and nothing in the Service constitutes medical advice, a diagnosis, or a treatment, rehabilitation, or physiotherapy plan.

Strength training carries a real risk of injury, including muscle strains, tendon and ligament damage, joint injury, dropped or mishandled weights, fainting and, in rare cases, serious or life-threatening cardiac events. You use the Service and perform any exercise at your own risk.

Consult a physician or another qualified healthcare professional before you begin any training programme, and in particular before using the Service if you have or have had a heart condition, high blood pressure, or a metabolic or musculoskeletal condition; if you are pregnant or postpartum; if you are recovering from surgery or injury; if you take medication that affects your heart rate, blood pressure, or balance; or if you are unaccustomed to physical exertion.

Train within your limits

Training plans, exercise instructions, load and volume suggestions, and coaching audio in the Service are general fitness guidance produced by algorithms and pre-recorded content. They are not tailored to your medical condition, your injury history, or your form on a given day, and they may be inaccurate, incomplete, or unsuitable for you. You are responsible for warming up adequately, selecting a load you can control, using correct form and appropriate safety equipment, and for the condition of your training environment and equipment.

Stop training immediately and seek medical attention if you experience chest pain or pressure, shortness of breath, dizziness or faintness, an irregular heartbeat, nausea, joint pain, sharp or sudden muscle pain, or any other symptom that concerns you. Do not push through such symptoms because a plan, a countdown, or the coaching audio tells you to continue.

Heart rate and body metrics are for reference only

Where you grant access to Apple Health, the Service reads your heart rate (during a workout, to display training intensity), body weight, height, body-fat percentage, and lean body mass, and writes back your body weight, height, and — if you train with the Apple Watch companion app — your completed workouts. How this health data is handled is described in the Privacy Policy.

Heart rate measured through Apple Watch and the body metrics read from and written to Apple Health are provided for general fitness reference only. They are not medical measurements, they may be delayed, inaccurate, or missing, and they must not be used to diagnose or monitor any medical condition or to make any medical decision. The Service does not monitor you in real time for medical purposes and cannot summon help; it is not a substitute for a qualified trainer, a training partner, or emergency medical services.

To the maximum extent permitted by law, you assume all risk arising from your use of the Service and from any exercise you perform in connection with it, and we are not liable for any injury, aggravation of an existing condition, or death resulting from that exercise. Nothing in this Section excludes or limits liability that cannot be excluded or limited under the law that applies to you, including liability for death or personal injury caused by our negligence.

7. Your Training Data

As you use the Service, you create training data — the plans, workout records (exercises, sets, reps, and weight), personal records, streaks, levels and experience, and world-map region progress associated with your account, together with the training profile you provide (such as sex, month and year of birth, goal, and preferences). You retain any rights you have in this data.

You grant SILVERDRAGON a worldwide, royalty-free, non-exclusive license to host, process, reproduce, and transmit your training data solely as necessary to operate, secure, and improve the Service, and to perform statistical analysis in an aggregated or de-identified form. The Service has no public posting, messaging, or content-sharing feature; you do not create content for other users. We handle your training data in accordance with the Privacy Policy, and we do not verify or warrant its accuracy, completeness, or validity.

8. Intellectual Property

The Service, including all software, text, audio, graphics, illustrations, characters, trademarks, and training content, is owned by SILVERDRAGON or its licensors and is protected by copyright, trademark, and other intellectual property laws. "vitalbay", together with its logos and product and service names, are trademarks of SILVERDRAGON. Except for the limited license in Section 4, these Terms do not grant you any right, title, or interest in or to the Service, and, without our prior written consent, you may not remove, obscure, or alter our copyright, trademark, or other rights notices.

9. Third-Party Services

The Service integrates with and relies on third-party platforms, including the Apple App Store and Google Play (distribution), Sign in with Apple and Google Sign-In (authentication), cloud-hosting and content-delivery providers, and analytics and crash-reporting providers. Any communication or business dealing you have with a third party through the Service is solely between you and that third party. Your use of such third-party services may be subject to their own terms and privacy policies, and SILVERDRAGON is not responsible for their content, practices, or availability.

10. Disclaimers

To the maximum extent permitted by law, the Service is provided on an "as is" and "as available" basis, without warranties of any kind, whether express, implied, or statutory, including merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, timely, secure, or error-free, or that any training or fitness outcome will meet a specific expectation. Any plan, instruction, coaching audio, heart-rate reading, or body metric obtained through the Service is used at your own discretion and risk, subject to Section 6. Nothing in these Terms excludes or limits any warranty or liability that cannot be excluded or limited under applicable law.

11. Limitation of Liability

To the maximum extent permitted by law, SILVERDRAGON and its affiliates, officers, employees, and agents shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenues, data, or goodwill, arising out of or in connection with your use of the Service. Because the Service is provided free of charge, our aggregate liability for any claim arising out of or relating to the Service shall not exceed one hundred United States dollars (USD 100).

These limitations do not apply to liability that cannot be limited under applicable law, including liability for death or personal injury caused by negligence, for fraud, or for gross negligence, or to any mandatory consumer-protection rights you have.

12. Indemnification

You agree to defend, indemnify, and hold harmless SILVERDRAGON and its affiliates, officers, agents, and employees from and against any claims, damages, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to your violation of these Terms, your misuse of the Service, or your infringement of any third-party right. This Section does not apply to consumers to the extent prohibited by applicable law.

13. Termination and Account Deletion

You may stop using the Service at any time and may request deletion of your account through the in-app settings or by contacting us at 3rd@silverdragonltd.com. We may suspend or terminate your access to the Service, with or without notice, if we reasonably believe you have violated these Terms, if required by law, or to protect the Service or its users.

Deleting your vitalbay account does not by itself revoke the authorization you granted through Sign in with Apple or Google Sign-In; you can revoke that separately in your Apple or Google account settings. How we retain and delete your data after termination, for the period necessary and as required by law, is described in the Privacy Policy. Sections that by their nature should survive termination (including Sections 6, 8, 10 through 12, and 15) shall survive.

14. Changes to the Service and the Terms

We may modify the Service at any time, including adding or removing features, and we may suspend part or all of it for maintenance, upgrade, or other purposes. We may also update these Terms from time to time. If we make material changes, we will provide notice (for example, via in-app notification) and update the effective date above. Changes take effect when posted, or on a later effective date specified by us. Your continued use of the Service after the effective date constitutes your acceptance of the updated Terms; if you do not agree, you must stop using the Service.

15. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the jurisdiction in which the operator is established, without regard to its conflict-of-laws principles. The parties submit to the exclusive jurisdiction of the competent courts located there, except where mandatory consumer-protection rules of your place of residence provide otherwise. Nothing in these Terms limits any mandatory statutory rights you may have as a consumer, nor your right to bring proceedings in the courts of your country of residence where applicable law requires.

The Service is operated from Singapore and hosted on cloud infrastructure in the United States. Where we transfer personal information across borders, including for users in the EEA or the UK, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses or the UK International Data Transfer Agreement, as described in the Privacy Policy. We do not represent that the Service is appropriate or available for use in every location.

16. Apple App Store Additional Terms

If you downloaded the Service from the Apple App Store, the following additional terms apply and prevail over any conflicting provision of these Terms for that purpose: (a) these Terms are concluded between you and SILVERDRAGON only, and not with Apple, and Apple is not responsible for the Service or its content; (b) the license granted in these Terms is limited to use of the Service on Apple-branded products that run iOS, iPadOS, or watchOS and that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions; (c) Apple has no obligation whatsoever to furnish any maintenance or support services for the Service; (d) Apple has no warranty obligation with respect to the Service, and in the event of any failure to conform to an applicable warranty you may notify Apple, and Apple will refund the purchase price (if any); (e) SILVERDRAGON, not Apple, is responsible for addressing any product-liability, legal, regulatory, consumer-protection, privacy, or intellectual-property claim relating to the Service; (f) you represent and warrant 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 listed on any U.S. Government list of prohibited or restricted parties; and (g) Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right to enforce these Terms against you.
