How sleep data is used

You're in control of how your Fitbit data is used. Your Fitbit sleep data is stored temporarily and used to give you info about your sleep, health, and fitness. Fitbit sleep data isn’t used for Google ads. This data also helps troubleshoot and improve your health and fitness experience with Assistant.
