Cleanzo

A deep cleaner for macOS — it only deletes confirmed junk, and proves it.

Cleanzo currently runs on Apple silicon Macs (M1 and later) only. Intel Macs are not supported yet — see GitHub for source and plans.

Cleanzo is a macOS app and doesn't run on Windows. See GitHub for future platform plans.

Junk clean

Scan with grouped built-in rules, review each item and check what to clean — you know exactly how much space you'll free before you do.

002 / 007

Lay your disk out as a drillable map to see exactly where the space went — no needle-in-haystack hunting.

003 / 007

List your biggest files at once, sorted by size and filterable by type or modified time — deal with the space hogs fast.

004 / 007

Find similar shots and bursts as groups, compare side by side, then clean in batches — originals and favorites are never touched.

005 / 007

Uninstall apps the drag-to-trash way, and sweep up the leftovers they scatter across preferences, caches and application support.

006 / 007

Recognize the cache directories of npm, pnpm, Bun, Cargo, Go, Xcode and more — reclaim tens of GB in one click.

Full Chinese and English UI that follows your system language, with a manual override.

The hard part of a cleaner isn't deleting more — it's proving nothing in use gets deleted. Cleanzo builds that line into the implementation.

Scanning is strictly limited to your home and temp directories — system paths and other users' data are out of reach.

Symlinks are resolved before deletion so the real destination stays inside the safe scope.

lsof checks whether a file is held by a process — in-use files and running apps' caches are always skipped.

Confirmed junk is deleted; personal files go to the Trash so you can always undo.

Libraries managed by apps (like your photo library) are recognized as a whole — never picked apart.

The dmg is signed and notarized by Apple, so it passes Gatekeeper normally.
