Designed to stay local
Your storage stays
on your Mac.
Diskmap processes file names, sizes, and scan results on your Mac. The app has no advertising, analytics, or account sign-in.
Full Disk Access is optional. Without it, Diskmap measures the locations macOS allows and identifies what it could not read.
