Everything stays on your Mac.

Online only for licensing

Barnook has no analytics, tracking or ads. It connects to barnook.pages.dev only when you activate a license, about once a week to recheck a purchased one, and when you deactivate it. It sends only the license key and a random number the app created. The server checks them with the payment company (Lemon Squeezy) and returns a confirmation that can’t be forged; it stores neither license keys nor IP addresses. If you only use the free tools, Barnook connects nowhere.

What the app reads

• Running servers: the ports used by programs you started, read with a tool built into macOS (lsof) and shown in the panel. Not stored.
• Clipboard: while auto-clear is on, only whether the clipboard changed. Never its contents.
• Mac settings: only the settings it shows and can revert.
• Power state: battery level and thermal state, for lid mode’s safety checks.
• Clearing hidden folder files: only files named .DS_Store inside a folder you pick.

What it stores

License and trial state live in a private file in your account (~/Library/Application Support/Barnook/License.json). App preferences and the original values of Mac settings you changed are stored in your macOS user account’s app preferences. While lid mode is on, the helper app keeps one empty marker file in /Library/Application Support/Barnook for recovery.

The helper app

The helper app does two things only: the setting that keeps the Mac awake with the lid closed, and refreshing web addresses. It talks only to Barnook signed with the same developer certificate.
