Each profile saves its files into its own folder
Files a profile downloads go into that profile’s own folder inside Mosaic’s data, not into one shared Downloads pile. The folder is kept out of Spotlight and deleted with the profile.

Downloads kept apart, step by step
Download as usual
The save dialog starts in the profile’s own folder.
Out of search
The folder is marked so Spotlight never indexes it.
Gone with the profile
Purge the profile and its files go too. Emptying downloads always needs a profile named; there is no unscoped wipe.
This keeps files apart and out of search. It is not encryption: Chromium writes the bytes as they are.
