uninvasive
Leaves boundaries intact
Uninvasive means not intrusive or penetrating—the opposite of invasive.
Medical procedures that are uninvasive don't require cutting into the body: an uninvasive screening test.
The word also describes behavior that respects boundaries: The interviewer's questions were uninvasive.
Noninvasive is more common in medical contexts, but uninvasive appears in general usage.
