Abstract: An in-vehicle relay device, an information processing device, a relay device, an information processing method, a non-transitory storage medium storing a program executable by a relay device, an information processing system, a vehicle, and an external device are disclosed. The in-vehicle relay device relays communication between a plurality of in-vehicle devices connected to an in-vehicle network mounted on a vehicle. The in-vehicle relay device includes a transmission part configured to transmit, based on a signal from an external device disposed outside the vehicle, first data stored in a first device that is one of the plurality of in-vehicle devices, and second data transmitted and received between the plurality of in-vehicle devices, to the external device.
