Terms of Service

Last updated: August 8, 2026

These Terms of Service (“Terms”) govern your access to and use of the Vaast mobile app, website, and related services (collectively, the “Services”), provided by Vaast Inc. (“Vaast,” “we,” “us,” or “our”). By creating an account or using the Services, you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the Services.

1. Eligibility

You must be at least 16 years old (or the minimum age required in your jurisdiction) to use the Services. By using Vaast, you represent that you meet this requirement and that the information you provide is accurate.

2. Your Account

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us promptly at support@vaast.ai if you believe your account has been compromised. You may close your account at any time.

3. Health & Safety Disclaimer

Important. Vaast provides training and fitness guidance for informational purposes only. It is not medical advice and is not a substitute for consultation with a qualified physician or health professional. Consult your doctor before beginning any training program, especially if you have a medical condition, are pregnant, or are new to exercise. You train at your own risk, and you are responsible for exercising judgment about your own limits. Stop and seek medical attention if you experience pain, dizziness, or other warning signs.

4. AI-Generated Guidance

Vaast uses artificial intelligence to generate and adapt training plans, workouts, and coaching suggestions based on the information and data you provide. This guidance is generated automatically, may contain errors, and may not be appropriate for every individual or situation. Always apply your own judgment and defer to a qualified coach or medical professional where appropriate.

5. Acceptable Use

You agree not to:

Use the Services for any unlawful purpose or in violation of these Terms.
Reverse engineer, decompile, scrape, or attempt to extract the source code or underlying models of the Services, except where permitted by law.
Interfere with, disrupt, or attempt to gain unauthorized access to the Services or related systems.
Upload malicious code, or content that is unlawful, harassing, or infringes others’ rights.
Misrepresent your identity or impersonate any person or entity.

6. Third-Party Services & Integrations

The Services let you connect third-party platforms and devices (for example, Garmin, Apple Health, Wahoo, Zwift, and others). Your use of those services is governed by their own terms and privacy policies, and we are not responsible for them. You authorize the flow of data you choose to connect, and you may revoke that access at any time through your account or device settings.

7. User Content & Community

The Services may let you share activities and interact with others through features such as friends, comments, reactions, and challenges (“User Content”). You retain ownership of your User Content, and you grant Vaast a non-exclusive, worldwide, royalty-free license to host, store, and display it solely to operate and provide the Services. You are responsible for your User Content and agree not to post anything unlawful, harassing, or infringing. We may remove content or restrict accounts that violate these Terms.

8. Intellectual Property

The Services, including all software, design, text, and branding, are owned by Vaast and protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Services for your personal, non-commercial use, subject to these Terms. All rights not expressly granted are reserved.

9. Disclaimers

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, and non-infringement. We do not warrant that the Services will be uninterrupted, error-free, or that any guidance will produce particular results.

10. Limitation of Liability

To the fullest extent permitted by law, Vaast and its affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising from your use of the Services. To the fullest extent permitted by law, our total liability for any claim arising out of or relating to the Services will not exceed the total amount, if any, you have paid us for the Services in the twelve (12) months preceding the date the claim arose.

11. Termination

You may stop using the Services and delete your account at any time. We may suspend or terminate your access if you violate these Terms or if necessary to protect the Services or other users. Provisions that by their nature should survive termination (such as intellectual property, disclaimers, and limitation of liability) will survive.

12. Changes to These Terms

We may update these Terms from time to time. When we make material changes, we will update the “Last updated” date above and, where appropriate, notify you through the app or by email. Your continued use of the Services after changes take effect constitutes acceptance of the updated Terms.

13. Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to conflict-of-law principles. You agree that any dispute arising out of or relating to these Terms or the Services will be subject to the exclusive jurisdiction of the state and federal courts located in Delaware.
