When you drag a macOS app to Trash, it leaves behind preferences, caches, containers, and logs in ~/Library. Crufti finds those leftover files and lets you remove them.

How much does it cost?

Crufti is a one-time purchase of $19. That includes a year of updates. After that, the app keeps working — you just stop getting new versions unless you renew. No subscription, no recurring charges.

Crufti uses a 3-tier confidence matching system, a blocklist of forbidden patterns, minimum 5-character matching, and user content detection to prevent false positives. Files go to Trash (not permanent deletion), and a JSON audit trail is created before every cleanup.

What macOS versions are supported?

macOS 14 Sonoma or later. Both Apple silicon and Intel Macs.

Why does it need Full Disk Access?

Some ~/Library locations (Containers, Group Containers) are protected by macOS. Without Full Disk Access, those folders are invisible. No data ever leaves your Mac — the permission is used for local scanning only.

Can I undo a deletion?

Yes — files move to Trash, so you can restore them anytime. Crufti also saves a deletion manifest locally so you have a record of exactly what was removed and when.

What is the Orphan Scanner?

It checks ~/Library for leftover files that don't belong to any currently installed app. Useful if you've been deleting apps without cleaning up for a while.

Does Crufti collect any data?

Zero. No analytics, no telemetry, no cloud sync. The only network request is checking for updates via Sparkle. Everything else stays on your Mac.

Delete Mac apps completely.

Crufti finds and removes every leftover file, cache, and preference when you uninstall a macOS app.

What is Crufti?

Crufti is a native macOS app that finds and removes leftover files when you uninstall applications. It scans 12 ~/Library locations for orphaned preferences, caches, containers, and logs — then lets you review and delete them safely. A lightweight, privacy-first alternative to AppCleaner or CleanMyMac for $19.

Dragging an app to Trash isn’t enough.

Every uninstalled app scatters preferences, caches, containers, and logs across a dozen ~/Library folders. Over time, gigabytes of cruft pile up.
