If you want to delete all the subject information from the device, navigate on the bottom navigation bar to 'Settings' and click on 'Reset'. For example, this may be helpful when a device was temporarily loaned to a subject, and you are now setting up the device for a new subject. Resetting the app will delete all the stored data, recordings, and anything related to the app and reset it to its original state. Be careful, all data are irreversible lost. After resetting you can scan a new QR code for a new patient.
