What SwingVantage measures, estimates, and does not measure

SwingVantage builds each result from the information you choose to provide:

• Manual answers — quick questions about your sport, miss, and experience.
• Imported data — launch-monitor or CSV data (e.g. FlightScope, TrackMan, Garmin) when you import it.
• Video — Motion Lab reads your body movement from a clip on your device and estimates angles and timing.
• Session history — patterns across the sessions you have logged.
• Profile & equipment — your level, goals, and gear when you add them.

When you have not provided measured data, SwingVantage gives its best estimate from your answers and well-established coaching patterns. Estimates are genuinely useful for picking one thing to work on first — but they are starting points, not measurements, and SwingVantage marks them clearly.

Unless a result is explicitly labeled as measured, SwingVantage does not:

• Measure exact joint angles from your video. Motion Lab estimates angles from a single camera, and labels them as estimates.
• Produce certified club-fitting or medical conclusions.
• Diagnose injuries or replace a physical therapist or doctor.
• Guarantee a specific score, distance, or performance improvement.

If a feature ever does measure your swing with validated video-processing or sensor logic, that result will say so plainly.

Every generated result carries a confidence level so you never see false precision:

• High — multiple data points support the result.
• Moderate — based on limited data; retest to confirm.
• Low — sparse data, such as self-reported answers alone; a starting point, not a diagnosis.
• Insufficient — not enough data to make a reliable recommendation.

Confidence rises as you add measured data, log more sessions, improve your input quality, and complete a retest.

Better input means a more trustworthy result. A clear camera angle, complete profile, imported launch-monitor data, and a couple of logged sessions all raise both the usefulness and the confidence of what SwingVantage gives you. Thin or unclear input keeps a result at the estimate level.

SwingVantage is an improvement assistant, not an authority. It is best used to prioritize practice and track change over time, then bring sharper questions to a qualified coach, club fitter, or trainer. For pain, injury, or safety-critical decisions, consult a licensed professional.

Without an account, your data stays on your device. When you sign in, your profiles, sessions, progress and your most recent swing analyses are saved to your own private account and follow you across devices. Video files do not upload unless you choose to share one for model training. Some optional features may need to send selected inputs for processing, and SwingVantage tells you when that happens. You own your data: you can export it, back it up, anddelete it at any time from the Data Center in your account. Our privacy policy sets out exactly what is stored and what leaves your device.

Improvement is shown conservatively. After you set a baseline and practice, SwingVantage prompts a retest (typically after 7 days) and compares results honestly — improved, some progress, no clear change yet, regressed, or inconclusive when the clips can’t be compared fairly. It will not claim progress it cannot support.
