With the Fitbit Alta, there is no factory reset option. Instead, your data will be automatically erased when it’s paired with a new account. Alternatively, you can erase your tracking data by removing the device from your account.
To delete the Fitbit app from your iPhone or Android phone, select the icon of a trash can in iOS or scroll to the bottom of your screen and press ‘Remove’. In the Fitbit web interface you can remove devices by going to Settings > About > Factory Reset > Clear User Data.
To remove a Fitbit device from your profile, launch the app and tap on “Today”. Tap on your profile picture, then find the image of the device you want to remove and scroll down.
