Question 1

Is DiskCleaner safe? Does it delete files permanently?

Accepted Answer

No file is ever permanently deleted. DiskCleaner uses macOS's native Trash system exclusively — every file moved is recoverable from your Trash. You also review every file before anything moves.

Question 2

Does DiskCleaner connect to the internet or collect my data?

Accepted Answer

Never. DiskCleaner runs 100% locally on your Mac. It makes no network calls, collects no data, and requires no account. Your file names and disk contents never leave your machine.

Question 3

What exactly does DiskCleaner scan?

Accepted Answer

Seven cleanup categories: App Cache, Browser Cache (9 browsers, all profiles), Screenshots, Trash Contents, System Logs, Developer Data (Xcode, Simulators, CocoaPods, npm), and App Leftovers. Deep Scan adds Large Files, Downloads, iOS backups, and Mail attachments. The RAM Optimizer monitors Memory Pressure, Swap, and Compressed Memory with one-tap optimization. The App Uninstaller removes apps and all associated leftover files. Personal files, passwords, and documents are never touched.

Question 4

Which macOS versions does DiskCleaner support?

Accepted Answer

macOS 13 Ventura through macOS 26 Tahoe. DiskCleaner is built as a native Universal Binary with full Apple Silicon and Intel support.

Question 5

How is DiskCleaner different from other Mac cleaners?

Accepted Answer

Most Mac cleaners delete files silently and show you a number after the fact. DiskCleaner shows you every single file before anything moves, with per-file checkboxes so you stay in control. It also never permanently deletes — everything goes through Trash.
