Is DiskCleaner safe? Does it delete files permanently?

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.

Does DiskCleaner connect to the internet or collect my data?

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.

What exactly does DiskCleaner scan?

Seven categories: App Cache, Browser Cache (9 browsers, all profiles), Screenshots, Trash Contents, System Logs, Developer Data (Xcode, Simulators, CocoaPods, npm), and App Leftovers from uninstalled apps. Personal files, passwords, and documents are never touched.

Which macOS versions does DiskCleaner support?

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

How is DiskCleaner different from other Mac cleaners?

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.

Do I need an account or subscription for DiskCleaner?

No account and no subscription. $9.99 one-time purchase covers you for up to 2 Macs and includes every future update.

Can I get a refund for DiskCleaner?

Yes. If you purchase through the Mac App Store, Apple's standard 14-day refund policy applies. For direct purchases, contact us at adminsupport@diskcleaner.pro.
