Which data does Ahead read from my wearable?

Only what your doctor uses to understand your health:

• steps and active minutes
• sleep duration and sleep score
• heart rate, resting heart rate and heart rate variability (HRV)
• weight
• workouts, from activity files

We read up to 90 days before your test date. From Google Health we keep heart rate, steps and other activity as one value per minute, and daily values such as resting heart rate as Google sends them. From uploaded files we keep only the values we use: the file itself is read in your browser and never leaves your device.

We keep your wearable data until you ask us to delete it.
