How do I erase my Fitbit device?

Before you give your Fitbit device to another person or return it, erase the device to remove apps, stored data, personal information, credit and debit cards* (for Fitbit Pay-enabled devices), and saved settings.

*Note that if you use Suica on your Fitbit device, erasing your Fitbit device doesn't remove Suica. Before giving your Fitbit device to another person, remove Suica in the Fitbit app.
