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

Scanning and cleaning run locally on your Mac. DiskCleaner collects no scan data and requires no account. Sparkle handles background app updates without sending your file names or disk contents anywhere.

Question 3

What exactly does DiskCleaner scan?

Accepted Answer

DiskCleaner scans 16+ categories and targeted cleanup locations, including App Cache, Browser Cache, Screenshots, .DS_Store files, macOS Trash, System Logs, Developer Data, Homebrew downloads, Movies, Downloads, Large Files, iOS backups, Apple Mail attachments, App Leftovers, external storage, local Time Machine snapshots, and old installers. The RAM Optimizer monitors Memory Pressure, Swap, and Compressed Memory with one-tap optimization. The App Uninstaller removes apps and associated leftover files. Protected paths are blocked. iCloud-safe scanning skips iCloud placeholder files and sync daemon caches so iCloud Drive can keep syncing normally while a scan runs. Risky or personal findings are never pre-selected.

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.

Question 6

Accepted Answer

DiskCleaner includes free core cleaning for App Cache, System Logs, Screenshots, .DS_Store files, and macOS Trash. A one-time $9.99 Premium purchase unlocks the full scanner for up to 2 Macs and includes all future updates — no subscription.

Question 7
