Nothing about you is sent anywhere: the room is drawn on this device, and the sound is made on it. Version 4.1.000.
The walls and the dome are two public-domain photographs of the real room, laid over a model built to its published size; the desks, lamps, chairs, carpet and the open volume are drawn for the scene. The sound is made on your device: the hush of a great stone room, a footstep far off and its echo, a page turned, a chair, the lamp at your desk. Nothing is recorded or fetched for it.
This page draws the room with script, which is off in this browser.
