No account, no tracking, no data collection. Your data stays on your Mac, and in your own private iCloud only if you turn on iPhone sync. Disk Usage never deletes or moves your files.
Questions
Do I need a Mac to use the iPhone app?
Yes. The iPhone app shows the disks of your Macs, synced by Disk Usage on the Mac. It does not measure the iPhone's own storage.
Can Disk Usage delete my files?
No. It reads your disks to show what takes up space. It never deletes or moves a file.
Which systems are supported?
macOS 14 or later on the Mac, iOS 17 or later on the iPhone.
Is it available in my language?
Disk Usage is available in 18 languages, including French, German, Spanish, Japanese and Chinese.
