Every app you open, every site you visit, every file you view — your Mac keeps records of all of it. CleanMachine finds and clears those traces, browser history, app state, and more. Including a one-tap Cave Mode for when privacy really matters.

Safari, Chrome, Firefox, Brave, and Edge each maintain separate databases of your browsing history, cookies, cached images, and download records. CleanMachine clears all of them — properly, by deleting the database files, not just marking entries as deleted (which still leaves them recoverable).
Every time you open a file, macOS adds it to a per-app recent documents list. This list is visible in the Dock context menu and File → Open Recent in every app. You can clear it in System Settings, or CleanMachine can clear all apps' recent lists at once.
macOS automatically saves application state so apps reopen to where you left them. This is convenient — but it also means sensitive document windows, terminal sessions, and chat conversations may reappear after restart on a shared machine.
Every time you press Space to preview a file in Finder, macOS stores a rendered thumbnail in a QuickLook cache. These thumbnails persist even after the original files are deleted — meaning someone can see what files you had by browsing the cache.
Your Mac's clipboard stores the last thing you copied — potentially passwords, API keys, or sensitive text. CleanMachine's Clipboard Wiper shows the current clipboard contents and wipes them with one tap. Auto-wipe timers (1/5/10/15/30 minutes) clear the clipboard automatically.
macOS Notification Center stores a history of all recent notifications — message previews, email subjects, and calendar events. This can be read by other users on a shared machine.
Clears browser history (all 5 major browsers), recent files, app state, QuickLook cache, notification history. Shows estimated size per category before you clean.
One-tap emergency privacy mode. Locks screen, kills apps with Screen Recording access, checks for MITM root certificates, then wipes clipboard, browser history, DNS cache, and shell history on exit.
Shows current clipboard contents with a live preview. One tap to wipe. Set an auto-clear timer (1–30 minutes) so sensitive copied text disappears automatically.
Reads the TCC database to show exactly which apps have access to your camera, microphone, screen recording, location, and contacts — with grant timestamps.
Scans Desktop, Downloads, Documents, and ~/.ssh for files matching sensitive patterns: SSNs, credit card numbers, private keys, and API credentials.
Verifies FileVault disk encryption status. Full-disk encryption is the most effective way to protect data if your Mac is lost or stolen. CleanMachine tells you if it's off.

Browser history and cache are separate from cookies. CleanMachine's privacy cleaner targets history and caches — not cookie files — so you stay logged in to your sites after cleaning. If you want to clear cookies too, you can do that from within each browser's settings.
Cave Mode is designed for situations where privacy matters immediately — before handing your Mac to someone else, presenting at a conference, or just wanting a complete session wipe. It locks the screen instantly, gives you a panel to kill apps with screen recording access, then wipes clipboard, browser history, DNS cache, QuickLook cache, temp files, recent documents, and shell history when you exit it.
Incognito mode doesn't write to the browser's main history database, so there's nothing to clear there. However, DNS cache (which records every domain your Mac resolved, regardless of browser mode) is cleared by Cave Mode.
