5. AI-Generated Content

The App uses artificial intelligence to generate personalized training plans, exercise recommendations, and coaching suggestions. This content is generated algorithmically based on the information you provide.

5.2 Not Medical or Professional Advice

AI-generated content is for informational and training purposes only. It does not constitute medical advice, professional athletic coaching, or physical therapy. You should:

  • Consult a qualified healthcare provider before starting any new exercise program, especially if you have injuries or medical conditions
  • Use your own judgment when following any training recommendations
  • Stop any exercise that causes pain or discomfort

5.3 No Guarantee of Results

We do not guarantee any specific training outcomes, performance improvements, or results from using the App. Individual results vary based on many factors outside our control.

6. Health and Safety Disclaimer

  • Physical activity involves inherent risks. By using the App, you acknowledge that basketball training and physical exercise carry risks of injury.
  • You assume full responsibility for your own health and safety while performing any exercises or training activities suggested by the App.
  • If you reported injuries during onboarding, the App will attempt to accommodate your constraints, but this is not a substitute for professional medical guidance.
  • We are not liable for any injuries, health complications, or damages arising from your use of training content provided through the App.

7. Intellectual Property

  • Results obtained from the App will be accurate or reliable
  • Any defects will be corrected

If negotiation fails, disputes shall be submitted to the competent court in the jurisdiction where we are located.
