Every tier runs entirely in your browser — no uploads, no tracking. Free forever for the core three points; Pro and Practitioner unlock the full ground-truth-measured library.
Why is calibration gated? Calibration is per-person accuracy tuning — the single biggest accuracy lever. It ships in paid tiers because it's the exact feature we built and measured, and it's what makes points like Kurcha genuinely accurate for your hand.
What happens if I cancel? Your practice history stays. You keep the free tier and all your data; paid features simply lock until you renew.
Is MarmaAI a medical device? No. MarmaAI is a wellness companion for guided self-touch practice — it does not diagnose, treat, cure, or prevent any condition. Point guidance is educational, not prescriptive.
