A cleanup advisor that explains itself

Every suggestion says why it was made and what removing it would mean. SpaceWise never decides for you.

Careful by design

Nothing happens without you. SpaceWise is built to make every removal deliberate.

  • Nothing is removed until you review it and confirm.
  • Items go to the Trash, so you can put them back until you empty it. Emptying the Trash is permanent.
  • System files, app bundles and app data are blocked as a safeguard.
  • Explanations never decide what can be removed; fixed rules do.
  • Sizes are estimates, and SpaceWise says so.

You decide what to remove and are responsible for those choices. Suggestions are a guide, not a guarantee, so check each item and keep a backup of anything important. Terms of use

Private. Really.

SpaceWise has no network access at all. It doesn’t collect, upload or share anything, and it reads only the folders you choose.

No network access

No analytics, telemetry, accounts or ads. The app makes no network connections.

Stays on your Mac

Scan history and settings are stored only in the app’s own folder on your Mac.

On-device intelligence

Explanations are written by Apple Intelligence on your Mac. File contents are never read for them.
