The AI agent for your Mac's storage

Your Mac's storage,
finally explained — and cleaned.

Crumb is a macOS menu-bar disk cleaner that audits your whole Mac — not just your home folder — so you can free up space on Mac without guessing what's safe to delete.

Crumb's Home view: a large 13.8 GB free readout with a disk-usage bar, a Crumb Intelligence card asking whether a folder is safe to delete, freed-space stats, and a tools grid.

The problem

Where did my space go?

Your disk says it's full, but Finder can only account for a fraction of it. Most Mac disk cleaners only scan your home folder — so the real hogs stay invisible. Crumb does a read-only audit of the whole machine and names them.

System Data

often 30–150 GB

The mystery bucket in Settings. Caches, logs, swap, and leftovers macOS won't itemize for you — Crumb breaks it down.

Time Machine snapshots

silent, local, growing

Local backup snapshots quietly held on your internal drive. They look like "free" space until they aren't.

Other users & hidden hogs

cross-account

Docker.raw's real vs. apparent size, iOS backups, swap — and a cross-user leaderboard showing which account is eating the disk.

Features

A storage agent that does the thinking for you

Crumb pairs a whole-Mac audit with AI that explains before it acts — so cleaning is informed, reviewable, and reversible.

Whole-Mac audit + cross-user leaderboard

A safe, read-only scan that surfaces the hidden hogs a home-folder cleaner misses: System Data, Time Machine local snapshots, Docker.raw's real-vs-apparent size, iOS backups, and swap. The cross-user view answers the question every shared Mac has: which account is using all the space?

Ask Crumb — is this safe to delete?

Tell Crumb a goal in plain English, or point it at any file. The AI explains what something is, whether it regenerates, and what breaks if it's gone — then proposes a reviewable, safe plan. Nothing happens until you approve it, so you delete with confidence, not anxiety.

Reclaim junk, by category

Crumb tallies exactly what's safe to clear — build artifacts, Xcode data, caches, package caches — and shows the total before you commit. Review the breakdown, see your largest items, and reclaim the space in a single click.

Crumb's Duplicates view listing 3,269 duplicate sets totalling 574.3 MB reclaimable, with a Remove button and duplicate groups that each have a checkbox and a Safe? check.

Power tools: Duplicates, Organize & Uninstall

Find duplicate files and remove the copies, uninstall apps along with every leftover, and tidy messy folders by type — the heavy-lifting toolkit, all in one menu-bar app. Each removal is checked and reversible, so nothing leaves without your say-so.

Private & reversible

File contents never leave your device. Crumb shows a clear plan before anything is moved or removed — like sorting loose Downloads into type folders — and reclaimable actions can be reviewed and undone after the fact, so you stay in control the whole way.

How it works

Three steps to a clearer Mac

STEP 01

Audit

Crumb runs a read-only scan of your whole Mac and maps where every gigabyte went — including System Data and other accounts.

STEP 02

Ask

Tell Crumb a goal in plain English, or tap a hidden hog. It explains what's safe and drafts a plan you can read line by line.

STEP 03

Reclaim

Approve the plan and watch the space come back. Reclaimable removals stay reviewable, so you're always in control.

Trust & privacy

Built to be trusted with your disk

Crumb is privacy-first and local by design. It earns access the boring, correct way — signed, notarized, and accountable.

Apple-notarized

Every build is submitted to Apple and notarized, so macOS Gatekeeper trusts it out of the box.

Developer ID signed

Code-signed with a verified Apple Developer ID — you always know exactly who built the app you're running.

Private & local

File contents never leave your device. The analysis runs on your Mac, for your eyes only.

No account required

Download and go. No sign-up, no email wall, no cloud profile — just an app that cleans your Mac.

FAQ

Questions, answered

Is my data private?
Yes. Crumb is private-first and local: the contents of your files never leave your Mac. The whole-Mac audit and the "is this safe to delete?" analysis run on your device, and there's no account, no sign-in, and no cloud profile to create.
Does it work on Apple Silicon?
Yes — Crumb is a universal app that runs natively on both Apple Silicon (M-series) and Intel Macs, on macOS 12 or later. It's Developer-ID signed and Apple-notarized, so it installs cleanly. The installer is roughly 11 MB.
What is System Data on Mac?
If you've ever wondered what is System Data on Mac: "System Data" (formerly "Other") is the catch-all category macOS shows in Settings → Storage. It bundles together caches, logs, swap files, system temporary files, and assorted leftovers — and Apple won't itemize it for you, which is why it can balloon to dozens or even hundreds of gigabytes. Crumb breaks System Data down into its real parts so you can see what's actually in there and safely free up space on Mac.
Lifetime or monthly — which should I pick?
Both unlock everything — Uninstall, Duplicates, Organize, Ask Crumb AI, and cross-user — with no feature limits, on up to 2 Macs. Lifetime ($49 once) is the best value: pay one time and it's yours forever. Monthly ($8.99/mo) is lower commitment and you can cancel anytime. If you plan to keep Crumb beyond about six months, Lifetime pays for itself.
How do refunds work?
If Crumb isn't right for you, just email hello@cleanwithcrumb.com and we'll sort out a refund. We'd rather you be happy than locked in.
Will cleaning break anything?
Crumb is designed to be safe and reversible. The audit is read-only, and before anything is removed you get a clear, reviewable plan. The "is this safe to delete?" AI explains whether a file regenerates and what depends on it, and reclaimable removals can be reviewed and recovered — so a cleanup is never a blind leap. Still unsure about a file? Ask Crumb first.
