PPG also known as Photoplethysmography is an optical non-invasive method for measuring the blood volume changes per pulse. It effectively represents the mechanical activity of the heart.

RPPG or remote Photoplethysmography is a method by which a face reader can measure heart rate and heart rate variability remotely. Where PPG is mostly used with wearable devices, RPPG detects the heart rate by using light and a completely contactless method. It measures the variance of red, green, and blue light reflection changes from the skin, as the contrast between specular reflection and diffused reflection.

Please refer to the following article which explains the process by which vital stats can be read using RPPG.https://www.noldus.com/blog/what-is-rppg

No, our algorithms adjust for makeup on the face.

We need normal lighting conditions for an effective reading, bright sunlight or glare affects the readings and are not recommended.

We’ve done many tests with a number of different skin tones.

No, our technology is agnostic to age.
Our readings depend on the speed of your internet connection, but on average take less than 60 seconds to perform.

We take your snap shots for processing in our secure Azure cloud, once we have extracted the vitals , all information is deleted and the only data we keep is the core vitals, time stamped with no personally identifiable information.
