Install

Download the disk image and open it.
Drag ZaynCleaner onto the Applications folder.
Open it. The first time, macOS blocks apps that aren't notarized yet: go to System Settings → Privacy & Security and choose Open Anyway.

Full Disk Access (recommended)

macOS hides some cache and log folders unless an app has Full Disk Access. Without it ZaynCleaner still works, but it can't measure or clean those folders. Open System Settings → Privacy & Security → Full Disk Access, add ZaynCleaner and turn it on, then reopen the app. Run Doctor in the logo menu shows whether access is granted.

The sections

Clean: scan, review each category, untick what you want to keep, then clean. Manage Separately lists large folders, such as VMs and backups, for size only.
Apps: uninstall apps with their leftovers (to the Trash), see Homebrew updates and manage startup items.
Optimize: a short diagnosis and the maintenance tasks it would run; admin tasks open in Terminal.
Analyze: a live treemap of your disk; right-click any tile for Copy Path, Reveal in Finder or Move to Trash.
Status: live health, CPU, GPU, memory, battery, disk, network and thermals, with a process list.

How it keeps your files safe

Clean removes only items the scan listed and you left ticked. Right before deleting, each path is checked again: it must be a full path that still exists, with no .., and it can never be a top-level system folder (/, /System, /Library, /Applications, /Users and so on) or your home folder. Paths you protect in Settings are never cleaned.

Questions

Is ZaynCleaner free?

Yes. It's free to download and use, with no account and no in-app purchases.

Can it delete something important?

It only removes items its scan found and you left selected. Each path is checked again right before removal, and top-level system folders and your home folder are always refused. Uninstalls and Analyze deletions go to the Trash, so you can put them back.

Does it send my data anywhere?

No. Scanning, cleaning and analysis run entirely on your Mac. It only goes online for things you start yourself, like the speed test or checking for updates.

Why do some actions open Terminal?

Tasks that need administrator rights run in a visible Terminal window, so you can see what happens and approve it with your password or Touch ID.

How is it related to Mole?

ZaynCleaner uses the open-source Mole command-line tool (GPL-3.0) as its cleaning engine and bundles it unmodified, source included. The app, interface, disk scanner and monitoring are ZaynStack's own. It isn't affiliated with the Mole project.
