Will I be charged automatically after DaisyDisk’s free trial ends?
No, the free trial is not limited in time (though some features will be locked), and you can try it as long as you like.
We don’t ask your credit card to activate the trial, so no charge can happen.
When you’re ready, click the Buy button and complete the checkout. To cancel the trial, simply delete the app.
Note that DaisyDisk’s license is a one-time purchase and NOT a recurring subscription – see more below.
Is DaisyDisk a subscription or a one-time purchase?
Good news, DaisyDisk is a one-time purchase, and we have no plans to switch to the subscription model.
The license is lifetime, and includes minor updates and bug fixes for a reasonable period.
If we release a major new version with lots of new features, it may be offered for a payment, but it will not invalidate your existing license. You will be able to use it as long as you like, and as long as it’s compatible with your current macOS.
Historically, 2 out of 3 major upgrades of DaisyDisk were also free of charge for the existing users.
Can I use my DaisyDisk license on my other Mac?
What’s the difference between stand-alone DaisyDisk and its App Store version?
Apple requires all apps submitted to the App Store to comply with certain rules, for security reasons and for their convenience of curation.
Unfortunately, these rules also make a few important features of DaisyDisk impossible to include in the App Store version.
For this reason we maintain two editions of DaisyDisk, and for those our App Store customers who need the extended functionality, we offer free migration to the stand-alone license.
Is there a Windows version of DaisyDisk?
Not right now, but we’re exploring the possibility. Stay tuned!
Why is DaisyDisk asking permission to access my Photos, Contacts, Calendar etc?
To size up your disk, DaisyDisk obviously needs to query sizes of all your files, including Photos, Contacts, Calendar and so on. Note that DaisyDisk only scans metadata — size and name — and not the actual content of the files. Unfortunately, macOS doesn’t make a distinction between metadata and content with its permission dialogs.
You can choose to deny the access, then you will simply get more “hidden space” in the report.
By contrast, if you want to reveal as much used space as possible, you can grant DaisyDisk “full disk access”, then the permission dialogs will not show up.
How safe is my data when I use DaisyDisk?
Your data always stays on your computer. Privacy is one of our core values. DaisyDisk doesn’t track, collect or transmit any files it scans. Besides, DaisyDisk scans only metadata of the files (name and size) — see more above.
How do I know what I can delete?
What if I accidentally delete a crucial system component?
This cannot happen — DaisyDisk has built-in safety stoppers that protect system components from deletion. On the lower level, macOS additionally protects its critical components.
The common precaution to take — as with any deletion tool — is to be careful not to accidentally delete your own files that you may still need.
Is there DaisyDisk for iOS — iPhone or iPad?
Unfortunately, there is no way to build DaisyDisk for iOS, because iOS “sandboxes” all its apps, which means each app can only access its own folder. It’s technically impossible for any iOS app to scan the entire disk of the device.
The closest alternative is to connect the iOS device to a Mac and scan it with DaisyDisk as an external drive. (A third-party software is required to mount the iOS file system to macOS.)
Note though, that some areas of the device’s disk will still be inaccessible, unless you jail-break the device (which we don’t recommend).
Besides, unlike macOS, the structure of iOS folders is quite opaque, and manipulating it directly may break the integrity of the system or the apps.
For these reasons, we recommend using the built-in space manager on iOS (found in System Settings).
Can I scan my iCloud storage with DaisyDisk?
Unfortunately, Apple doesn’t currently provide an API to scan the iCloud, unlike other cloud services.
The closest alternative is to use the “Scan Folder…” button and select the iCloud Drive in the sidebar of the Open dialog. However, this will only scan the local cache of your iCloud Drive. Also note that iCloud Drive is only a small part of the iCloud — the report will not include other big parts, such as Photos, Mail, Backups etc.
Does DaisyDisk support the new Apple M2 chip, new macOS Ventura?
Can DaisyDisk detect duplicate files?
No, because finding and removing duplicate files requires a completely different user interface. And if we made one, it would be a separate app.
