Reclaim space.
Respect your privacy.
A modern Mac cleaner that's safe by default. Smart Clean in one click, complete uninstaller, duplicate finder — all on-device. No cloud uploads. No telemetry.
How it works
No wizards. No drama. Three steps.
No "we found 9,847 problems!" theatrics. Just transparent scanning and clean, reversible actions.
Launch & scan
Open StayCleanMac and run a Quick Scan. Every category scans in parallel on Apple Silicon — dashboard stays responsive the whole time.
Review findings
Every category shows exact file paths, sizes, and contextual notes. Smart Clean pre-selects only items macOS will rebuild on demand.
Clean with Undo
Everything goes to Trash first — nothing is permanently deleted. Press ⌘Z or tap Undo in the toast to restore instantly.
Six ways to clean
Six tools.
No bundleware.
Six focused tools instead of fifty. Each one does one job, transparently, and reversibly.
Smart Clean, one click
Automatically identifies safely-regenerable caches and moves them to Trash. macOS rebuilds them on demand — you just get the space back.
Complete Uninstaller
Finds every trace — support files, caches, preferences, even permissions granted in System Settings.
Caches & Logs
Safely remove regenerable cache files from browsers, apps, and system temp — all with explicit file-by-file preview.
Large Files
Surface disk space hogs sorted by size. Disk images, forgotten backups, 4K videos — all in one sortable list.
Duplicate Finder
Content-hash matching groups identical files. Keep suggestions pick the newest; you review every decision.
Startup Manager
See everything that launches at login — Launch Agents and system daemons alike. Toggle each one; StayCleanMac handles the permissions.
Privacy & safety
Your Mac.
Your data. Nobody else's.
Every scan runs on your Mac. Nothing uploads, nothing phones home. If your network disappears mid-scan, StayCleanMac doesn't notice or care.
No cloud uploads, no telemetry
Zero outbound connections during scans. No analytics, crash reports, or "anonymized usage data."
Trash-first, always
Every action moves files to Trash — never permanent delete. You stay in control of the final empty.
Undo everything with ⌘Z
A toast appears after every operation. Tap Undo or press ⌘Z within 10 seconds to instantly restore.
Signed, notarized, hardened
Developer ID signing, Apple notarization, hardened runtime. Updates delivered securely via Sparkle with EdDSA signatures.
Four languages
Localized by humans, not Google.
Every string hand-written for natural reading in each locale.
Questions, answered
Frequently asked.
Is StayCleanMac really free?
Why does it need Full Disk Access?
~/Library/Caches and ~/Library/Preferences, plus system paths like /Library/LaunchDaemons. macOS requires explicit permission for these. You grant it once at first launch through System Settings — StayCleanMac never transmits what it finds.What if I accidentally delete something important?
⌘Z or tap Undo within 10 seconds to instantly restore. Beyond that, items live in your Trash until you empty it. The only exceptions are system-level startup items and permission resets — those are noted explicitly and cannot be undone.How is this different from CleanMyMac or similar apps?
