What it does
Six tools. One quiet app.
Each one earns its place. No bloat, no fake "speed up" buttons, no nagware.
Duplicate finder
Exact SHA-256 duplicate groups across your scan. See wasted space, review, reclaim.
Similar media
Perceptual hashing for photos and screenshots — find near-duplicates that look the same but have different bytes.
App uninstaller
Removes apps along with the leftover preferences, caches, support files, and login items they hide in your Library.
Quick cleanups
Xcode DerivedData, Homebrew cache, Trash bins across every drive — one click, review-before-trash.
MCP for AI agents
Built-in Model Context Protocol server lets Claude Code, ChatGPT Desktop, or Cursor read your scan results — destructive tools default off.
Privacy
Your files never leave your Mac.
No analytics SDK. No tracking pixels. No "share usage data" toggle hiding a Mixpanel client. Power Cleaner Studio doesn't have a server — it can't phone home because there's nowhere to phone.
- Scans run locally — paths and file hashes stay on your Mac.
- MCP server (optional) listens only on localhost with a bearer token.
- Destructive cleanup goes to Trash — every action recoverable for 30 days.
- Sandboxed Mac App Store build. No Full Disk Access required.

Questions
Honest answers. No marketing fluff.
Is it really one-time, or is there a subscription somewhere?
One-time. $9 unlocks every Pro feature on every Mac you sign into with the same Apple ID. No subscription, no renewals, no email signup.
Do my files leave my Mac?
No. Every scan, hash, and analysis runs locally. There is no analytics SDK, no telemetry, no cloud upload. The optional MCP server only listens on localhost.
Does it need Full Disk Access?
No. We work inside the folders you grant via the standard macOS file picker — Downloads, Documents, your scan roots. The Mac App Store build is fully sandboxed.
Can it delete the wrong thing?
Defense in depth: every destructive call goes through a path policy that rejects critical paths (/System, ~/Library/Mail, ~/.ssh, etc.), MCP cleanup tools refuse anything not in the last scan report, and every delete goes to Trash — recoverable for 30 days.
Does it run on my Mac?
macOS 14 Sonoma or later, Apple Silicon or Intel. No background helper, no kernel extension.
Where's the trial?
Free tier IS the trial. Browse duplicates, similar media, and the uninstaller for as long as you want. Cleanup actions ask for the one-time purchase when you click them.
Give your Mac its space back.
Free download. $9 to unlock cleanup actions. No subscription, ever.
