Crumbs

Crumbs Privacy Policy

Effective date: September 26, 2026

Crumbs is a macOS app that scans folders you choose for leftovers from AI coding agents and build tools, such as git worktrees, node_modules and build output, and helps you move the ones you no longer need to the Trash.

Crumbs does not collect, sell, share, or transmit any data to the developer or to any third party. Everything it reads and everything it stores stays on your Mac.

What Crumbs Reads

To decide whether a folder is safe to remove, Crumbs reads the following on your Mac:

  • File and folder names, sizes and modification dates inside the folders you ask it to scan.
  • Git state of repositories and worktrees it finds, by running your local git: current branch, uncommitted changes, and whether commits exist on other branches or remotes. These git commands do not contact any server.
  • The working directories of running processes, to tell whether a folder is in use.
  • The contents of files that look like credentials (for example .env.local), only to compare them byte for byte with the same file in the main checkout. Contents are never stored or displayed.

What Crumbs Stores

  • Your settings (folders to scan and per-rule waiting periods) in the app's standard macOS preferences.
  • The results of the last scan, including folder paths, sizes and the names of secret-looking files, in ~/Library/Application Support/Crumbs/last-scan.json, so results appear instantly on the next launch.

Deleting the app and that folder removes everything Crumbs stored.

Network Requests

Crumbs makes no network requests. It has no accounts, analytics, telemetry, crash reporting, advertising, or remote configuration. Checking for updates is up to you, via the GitHub releases page.

The Help menu and menu bar include links to this website, GitHub and the feedback form. They open in your browser only when you click them. The feedback link includes the app version so reports can be matched to a release.

Removing Files

Crumbs never deletes files. Items you choose are moved to the macOS Trash, where you can restore them until you empty it. After a git worktree is moved to the Trash, Crumbs runs git worktree prune in its repository so git stops listing it.

macOS Permissions

If a folder you scan is in a protected location such as Documents or Desktop, macOS may ask whether Crumbs can access it. Declining only means Crumbs will not scan that folder.

Open Source

Crumbs is open source under the MIT license. You can read exactly what it does at github.com/nilveryboring/crumbs.

Feedback

If you choose to send feedback, the form is hosted by Makeform. What you submit, including an optional email address or screenshot, is used only to read and reply to your feedback and to improve Crumbs. It is never sold or shared. Sending feedback is always optional.
