Does Storage Studio report which apps I use?
Short answer: No. Your app list, sizes and last-used dates are read on your Mac to suggest what to move, and they stay there. App names aren't part of what Storage Studio reports.
No. The Apps window reads your apps, their sizes and when you last used them on your Mac so it can suggest what to move — and that list stays on your Mac. App names aren't included in what the app reports.
The same goes for Tuhi: when it tells you which app is using space, it works that out on your Mac.
See Apps for how the Apps window works.
