Fantasy
Fantasy cultures get more interesting when privacy is treated as a real social rule, not a decorative extra.
Anyone can invent scales, horns, telepathy or hive minds. Fine. The sharper question is what counts as rude, sacred or dangerously public. Who is allowed to overhear a name. What can be spoken in daylight. Which memories are communal and which are kept shut away like knives.
That’s where worldbuilding stops being costume and starts becoming pressure. A culture’s ideas about privacy tell you who has power, who is exposed, and what kind of person the story thinks is normal. Which is usually where the trouble starts.
