Questions.
How much does StorageJanitor cost?
It is free to scan and to remove up to 2 GB in total. The full version is $9.99, paid once.
Does the 2 GB reset?
No. It is a one-time allowance across everything you remove, including items moved to the Trash. An item bigger than what is left is skipped. Reinstalling the app, or deleting its history, doesn't bring it back.
Is there a subscription?
No. There is no subscription and no account.
Is StorageJanitor free?
Partly. The free version scans your whole disk, explains every item, and removes up to 2 GB in total, including uninstalling apps. Everything beyond that is in the full version, $9.99 paid once.
What does the full version add?
Removal with no limit; fixes for local Time Machine snapshots and an oversized Spotlight index; every suggestion list (unused apps, old backups, large old files, leftovers, developer files); the list of what grew since an earlier scan (a day or more ago); and an optional low-disk warning.
Do I get updates?
Yes. The app checks for updates and installs them from inside the app.
Which Macs does it run on?
Macs with Apple Silicon (M1 and later). It scans the internal disk.
Can I buy it now?
Not yet. StorageJanitor isn't on sale or available to download yet. These are the prices it will have at launch.
