Estimates, not medical results
All results are estimates and cannot provide or replace medical advice or clinical measurements. LumaSignal is for adult personal wellness records and information only. It is not a medical device and is not intended to diagnose, treat, cure or prevent any disease or health condition.
Limitations
Optical pulse estimates vary with lighting, movement, skin characteristics and hardware. A 30-second capture is not a clinical examination; overlapping pulse estimates are not beat-to-beat intervals or face HRV. Sleep observations cannot diagnose sleep disorders or provide measured sleep stages. Meal photos may miss ingredients, allergens and portions. Do not use results to make medical, medication or allergy-safety decisions.
Seek qualified help
If you have symptoms or concerns, seek a qualified healthcare professional. A normal estimate cannot rule out illness; an unusual estimate is not a diagnosis. For emergencies contact local emergency services. Do not wait for another app check. Cited sources and institutions do not endorse LumaSignal.
