@natalie_jacoba this would depend on which operating system the phone has.if it is lollipop or earlier than you gave it permission when installing. In Marshmellow tour able to turn on amd of the permissions seperate through Settings - Applications - Fitbit - Permissions.
Location is needed for the GPS tracking, and in Marshmellow it is also needed to sync. If your fitbit app needs location and it is turned off, it will tell you. Or 8n Marshmellow it will ask if youll give fitbit permission.
