Help & FAQ
Questions, answered.
Is Luma a medical device?
No. Luma supports informational and general-wellness use and does not diagnose, monitor, predict, prevent, or treat a health condition.
Why is a camera reading unstable?
Movement, pressure, temperature, lighting, device hardware, breathing, and fingertip placement can affect the estimate. Follow the in-app guidance and try again at rest.
Are camera frames saved?
No. Frames are analyzed live for pulse-related light changes and are not retained as photos or video.
How do I take a camera reading?
Sit at rest, place a fingertip gently over the camera and flash as shown in the app, keep still, and stop if the phone becomes uncomfortable or the reading feels difficult.
Can Luma read Apple Watch or Apple Health data?
Only when the relevant integration is available and you grant permission. You can review or revoke Health permissions in Apple’s system settings.
How do I manage a purchase or contact support?
Use Restore Purchases with the original store account. Manage subscriptions or refund requests through Apple or Google, and contact Gamina support for measurement or app issues—not urgent medical help.
