"Factory Reset is found on your Fusion 2, under apps > settings , and will delete all the recorded data on your Fusion 2 (data already synced to your phone will remain on our servers linked to your account) and restore it to factory settings. Your Fusion 2 will display "striiv.com/start" and battery % as it did coming out of the retail box. After doing a Factory Reset, you'll have to re-pair your device to your phone.
