HOW DO I DELETE PROFILE DATA FROM MY TRACKER? Fitbit uses your height, weight, and age measurements to properly calculate your stride length (which helps determine your distance), calorie burn, and active minutes.

To delete your profile measurements from your tracker, the tracker must be set up to a different account. Once a tracker is set up to a different account, it will automatically unlink itself from the dashboard and all of the tracker's stored data will be permanently deleted from the tracker. You can find instructions on how to create a new account in the following articles:

• How do I set up my Fitbit tracker on a computer?
• Setting up your tracker with the Fitbit app for iOS
• Setting up your tracker with the Fitbit app for Android
• Setting up your tracker with the Fitbit app for Windows Phone

You must use the app or Fitbit Connect to set it up. The Bluetooth settings screen on the phone or computer will not work.
