私 carries the sense of self or private (vs 公 public), and 人 means person. Together 私人 literally reads private-person, covering both personal relationships and private/non-official matters.
人 — pictograph of a standing person
人 is a pictograph showing a person viewed from the side, with two strokes representing the legs and torso of a standing human. In oracle bone script it clearly depicted a figure leaning slightly forward. The meaning has remained 'person' or 'human' throughout its history.
