What PostureCheck is
PostureCheck is a posture habit tool. It estimates changes in your upper-body posture from a webcam and reminds you to sit well. It is not a medical device and doesn't diagnose, treat or prevent any condition. Its score is an estimate that depends on your camera, lighting and calibration. If you have pain, numbness or an injury, see a qualified health professional.
Free use
The free posture check includes a daily allowance of live tracking. We may change the allowance, and we'll say so on the pricing page when we do.
Pro
Pro is sold as a license key. The monthly plan renews automatically every month until you cancel; you can cancel any time from your Stripe receipt email, and access continues to the end of the paid period. The lifetime plan is a single payment and never renews. A key may be activated in up to five browsers. Keys are for one person and may not be shared or resold.
Refunds
If Pro doesn't work for you, email Mark@Reinventing.AI and I'll refund you.
Availability
The posture check runs in your browser and needs a webcam and a current browser. Some features, like the floating monitor, depend on browser support. We provide the service as it is, without warranties, and our liability is limited to the amount you paid in the 12 months before a claim.
