Young athletes can use it with an adult involved. SwingVantage is not directed to children under 13, analysis runs on your device by default, and nothing is shared publicly. A parent or guardian should supervise practice and record consent in Settings.

For a child under 13, a parent or guardian must set up and manage the account. For ages 13–17, a parent or guardian should review how SwingVantage works and record their consent.
Features that send data off the device are more restricted for young athletes: for an athlete you have said is under 18, AI Coach and the optional AI second opinion stay locked until consent is recorded, and the optional cloud re-read needs a linked guardian.
It gives practice guidance, not medical advice, and drills should always be supervised. See what to do about pain.
