What data do we collect?Updated 3 months ago

There are many types of data we store for different reasons:  
Account information
Email:  We need to verify you are a user with a real email so any important notifications (such as app refreshes, term of use updates,  and privacy policy changes) will reach you.
Personal data:  When calculating your sleep score, we start with numbers that correspond to published averages.  However, sleep requirements vary for everyone.  There is research suggesting that age and sex (assigned at birth) are the most important determinants when assessing a person's sleep.  
Sleep Data:  We collect heart- and respiration-rate along with body movement information in order to determine each stage of sleep you are in.
