Last updated: March 2026 · G PRO AI Lab

These Terms of Service ("Terms") govern your use of AI Goniometer at gproailab.com ("the Service"), operated by G PRO AI Lab ("we", "us", "our"). By using the Service, you agree to these Terms.

⚠️ AI Goniometer is a personal assistive tool, not a medical device. It does not provide medical diagnosis, treatment recommendations, or clinical assessments. Always consult a qualified healthcare professional for medical advice regarding your recovery.

1. Description of Service

AI Goniometer is an online tool that uses artificial intelligence to measure and calculate joint angles from user photos. It is designed to help users measure and track joint angles over time.

2. Not a Medical Device

The Service is not a registered medical device and has not been cleared or approved by any health regulatory authority (including the FDA, CE, or equivalent). The angle measurements provided are estimates based on AI detection and may not be accurate in all circumstances. Do not make clinical decisions based solely on measurements from this tool.

3. Eligibility

You must be at least 18 years old to purchase a subscription to the Service. By subscribing, you confirm that you are at least 18 years of age.

4. Free Tier and Subscriptions

Free tier: New users receive 5 free measurements after signing in with Google.

Paid subscriptions: After exhausting free measurements, continued use requires a paid subscription:

  • Quarterly plan: $24.99 / 3 months

Subscriptions are processed by Creem and are subject to Creem's payment terms. Prices are listed in USD.

5. Auto-Renewal and Cancellation

Subscriptions automatically renew at the end of each billing period. You may cancel at any time through your account settings or by contacting us at support@gproailab.com. Cancellation takes effect at the end of the current billing period — you will retain access until then.

6. Refund Policy

We offer refunds within 7 days of the initial subscription payment if you are not satisfied with the Service. To request a refund, email support@gproailab.com within 7 days of purchase. Refunds for subsequent renewal periods are not provided except where required by applicable law.

All content, code, and design of the Service are the property of G PRO AI Lab. You retain ownership of any images you upload. By submitting optional feedback images, you grant G PRO AI Lab a non-exclusive, royalty-free license to use those images solely for improving AI detection accuracy.

10. Disclaimer of Warranties

The Service is provided "as is" without warranty of any kind, express or implied. We do not warrant that measurements will be accurate, that the Service will be uninterrupted, or that it is free from errors. Use of the Service is at your own risk.

11. Limitation of Liability

To the fullest extent permitted by law, G PRO AI Lab shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Service, including but not limited to decisions made based on measurements provided by the tool.

We may update these Terms from time to time. We will notify you of material changes by posting a notice on the website. Continued use of the Service after changes constitutes acceptance of the updated Terms.
