Terms of Use
Last updated
These terms apply to your use of VitalStep (vitalstep.pro), operated by MyGPT Software Joint Stock Company (MyGPT Jsc), Vietnam ("we", "us"). By using VitalStep you agree to them. If you do not agree, please do not use the service.
1. VitalStep is not medical advice
VitalStep offers general exercise information, AI-generated workout plans and links to third-party exercise videos. It does not diagnose, treat or prevent any condition and is not a substitute for advice from your doctor, physical therapist or other qualified professional.
- Talk to your clinician before starting a new exercise program, especially if you have heart disease, high blood pressure, diabetes, recent surgery, pain or any condition listed in the app.
- AI-generated plans can contain mistakes. Use your judgement and adjust or skip anything that does not feel right.
- Stop exercising and seek medical help if you have chest pain, severe shortness of breath, dizziness, fainting or other warning signs. In an emergency, call your local emergency number.
You exercise at your own risk and are responsible for choosing activities that are safe for you.
2. Who can use VitalStep
You must be at least 18 years old. You can use VitalStep without an account; your data is linked to your device as described in the Privacy Policy.
3. Free and Premium
The core features are free. VitalStep Premium adds extra features described on the Premium page. Premium is sold as a subscription through PayPal:
- Price: the price shown on the Premium page (currently US$5.99 per month or US$49.99 per year) is the amount you pay. There are no setup fees and no free trial.
- Renewal: your subscription renews automatically each month or year and PayPal charges you on each renewal until you cancel.
- Cancel anytime: cancel in your PayPal account (Settings > Payments > Automatic payments). Premium stays active until the end of the period you have already paid for, and you will not be charged again.
- Refunds: if you were charged by mistake or something did not work, email us at thaitq@mygpt.vn and we will look at it fairly. This does not limit any refund or withdrawal rights you have under the consumer law of your country.
- Price changes: we will tell you before a price change applies to your subscription, and you can cancel before it takes effect.
- Premium is linked to the device used to subscribe (and a second linked device). If you change device or clear your browser data, you can restore it with the PayPal account you paid with.
4. Videos and third-party content
Workout videos are created by independent creators and played from YouTube. They belong to their creators, are subject to YouTube's terms, and may be removed by their owners at any time. We add condition tags, guides and safety notes, but we do not control the videos themselves. Links to other websites are provided for convenience; we are not responsible for their content.
5. Acceptable use
- Do not misuse the service, for example by attempting to access other users' data, bypassing payment or usage limits, or sending automated requests in bulk.
- Plans you share to Community Plans must not contain personal health details of other people, unlawful or offensive content. By sharing, you allow us to display them publicly in VitalStep. You can ask us to remove them.
- We may apply fair-use limits to AI features and may suspend access that abuses the service.
6. Our content
The VitalStep app, design, text and guides belong to us or our licensors. You may use them for your personal, non-commercial use.
7. Availability and changes
VitalStep is a new product and is provided "as is". We may change, add or remove features and may interrupt the service for maintenance. If we stop offering Premium, we will stop renewals and handle the unused part of any paid period fairly.
8. Liability
To the extent permitted by law, we are not liable for indirect or consequential losses, or for injury resulting from exercise you choose to do, and our total liability is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, including your statutory rights as a consumer.
9. Law
These terms are governed by the laws of Vietnam. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring claims in your local courts where the law allows.
10. Changes to these terms
We may update these terms. We will change the date above and, for important changes, let you know in the app before they apply.
