unadvertised

Kept from publicity

Unadvertised describes something not publicly announced or promoted.

An unadvertised sale isn't in the flyer but exists if you know to ask.

Unadvertised job openings circulate through networks rather than postings.

The word often implies insider knowledge or deliberate discretion: The restaurant has an unadvertised menu for regulars.
