An information processing device includes circuitry to determine a connection state between the information processing device and an information device locally connected to the information processing device. The circuitry further transmits, to a device management apparatus connected to the information processing device through a network, information on the information device acquired from the information device when the connection state is a first state. The circuitry further deletes the information on the information device managed by the information processing device when the connection state is a second state.
