3. Volleyball and AI disclaimer

VBall AI provides automated, informational feedback based on visible video content. It is not a substitute for a qualified coach, trainer, medical professional or safety assessment. AI output may be incomplete, inaccurate or unsuitable for your circumstances.

Stop training and seek appropriate professional advice if you experience pain, injury or health concerns. You remain responsible for training decisions and safe use of equipment and facilities.

4. Your content

You keep ownership of your videos and other content. Original videos remain on your device. When you request an analysis, selected keyframes are sent to the VBall AI backend and processed through the service providers described in our Privacy Policy.
