Your disk is your business.

The short version

OpenDisk collects no data. There is no telemetry, no analytics, no account, and no server that ever sees the contents of your disk. The code is open source under the MIT license, so you can verify every word of this policy yourself.

The app

Everything OpenDisk does happens locally on your Mac. When you scan a drive, the file names, sizes, and folder structures it reads are used only to draw the chart on your screen. Nothing is uploaded, logged, or shared, and nothing persists outside the app's own local cache on your machine.

OpenDisk asks for Full Disk Access so macOS lets it see the whole filesystem. That permission is used solely for scanning. The app makes no network requests while scanning.

Automatic updates

OpenDisk uses Sparkle, the open-source update framework, to check for new versions. An update check fetches a small static file (the appcast) from this website. That request contains no personal information, no identifiers, and no details about your Mac or your scans. Updates are EdDSA-signed and verified before installing. You can disable automatic update checks in the app at any time.

This website

This site sets no cookies and runs no analytics, trackers, or advertising scripts. Like any web server, the host may keep standard technical logs (such as IP address and requested URL) for security and operations. We do not use those logs to identify or profile anyone.

Downloads

App downloads are served from GitHub Releases. When you download OpenDisk, GitHub's own privacy policy applies to that request, as it would for any file hosted on GitHub.

Changes to this policy

If this policy ever changes, the new version will be published on this page, and the change will be visible in the site's open-source history like everything else.
