When you connect your Fitbit for the first time you are presented with a data permissions screen.

Allow All (KrowdFit needs this permission) 

• food and water logs
• heart rate
• weight
• activity and exercise
• profile
• sleep
• Fitbit devices and settings
• location and GPS

KrowdFit requires permission across all of these data points in order for our reconcile summary to work. If you disable one of them then some of the activity counts may not get updated.
