간략 답변
Private characters are useful for unfinished cards, personal stories, imported cards that need cleanup, and roleplay ideas the creator does not want indexed or discovered by strangers.
쉽게 설명한 뜻
It is a character for you or your testing workflow, not a public profile for everyone browsing the catalog.
Private-character searches connect creator control, privacy, public discovery quality, and safer publishing workflows.
OnlyKin should keep private drafts central because better private testing creates better public characters.
