Debris · last updated 6 September 2026
Debris does not collect any data.
The app has no user accounts, no analytics, no advertising, no crash reporting, no update check and no third-party code. It makes no network connections at all. The developer receives nothing about you or your Mac, because there is nothing in the app that could send it.
Debris reads the places where macOS and your apps keep their files: the Applications folders, the Library folders in your home folder and on the system, launch agents and daemons, package receipts, the Homebrew directories and the Spotlight index. That is how it works out what is installed and what is left over. It reads the names, sizes, dates and bundle information it needs for that, and the code signature of installed apps to learn which files they own. It never reads the contents of your documents, mail, browsing data or passwords.
macOS hides parts of the Library from every app until you grant it Full Disk Access in System Settings. Debris asks for it so that it can see inside sandboxed app containers, Mail, Safari and cookie storage, and move leftovers from those places to the Trash. To find out whether it has the permission, the app tries to open one protected system file and closes it again without reading anything. The permission is yours to grant or withdraw at any time in System Settings.
Files owned by the system can only be moved with administrator rights. When such files are on the list, macOS shows its own password prompt. Debris never sees the password; it only receives the result of the move.
Debris keeps no settings and no history of its own. macOS may store window positions in the app's preferences file, which stays on your Mac and is deleted when you delete the app. Whatever you remove goes to the Trash, where it stays until you empty it.
The app is not directed at children, and collects nothing from anyone.
Any change to this policy will be published on this page with a new date.
