Question 1

Is ZaynCleaner free?

Accepted Answer

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

Question 2

Can it delete something important?

Accepted Answer

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.

Question 3

Does it send my data anywhere?

Accepted Answer

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.

Question 4

Why do some actions open Terminal?

Accepted Answer

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.

Question 5

How is it related to Mole?

Accepted Answer

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.

Question 6

What does ZaynCleaner need to run?

Accepted Answer

A Mac with Apple Silicon (M1 or newer) running macOS 12 Monterey or later. Granting Full Disk Access lets it measure every cache folder, but it works without it.

Question 7

Why does macOS warn me the first time I open it?

Accepted Answer

This early build is not yet notarized by Apple. Open it once from System Settings → Privacy & Security → Open Anyway. After that it opens normally.
