ModScan Privacy Notice

ModScan is a local command-line tool from Kaizōsha. This notice describes the behavior found in the current published ModScan 1.0.1 source. Kaizōsha's website has a separate privacy policy for visits to this website.

Last updated: August 20, 2026

ModScan 1.0.1 has no account, advertising, analytics, tracking, crash-report upload, cloud-sync service, or runtime network-request code. Kaizōsha does not receive filesystem paths, project names, directory sizes, modification dates, scan results, or deletion activity through ModScan.

ModScan does not sell or share scan data with advertisers, data brokers, or analytics providers.

A default scan recursively inspects the current working directory. A --global scan inspects the home folder, common development locations, and available Windows drives while skipping inaccessible, hidden, cache, and selected system paths.

ModScan reads file and directory metadata to calculate size and modification age. It reads a parent project's package.json file to obtain the project name shown in the terminal. This processing happens in the local Node.js process.

Scan results, filter state, sort state, and the running total of freed space are held in memory for the current terminal session. The current release does not create a scan database or upload scan results.

Closing ModScan ends that in-memory session. ModScan does not provide an account or cross-device synchronization.

The deleted directory's former size is added to the in-memory freed-space total. ModScan does not send the selected path or deletion result to Kaizōsha.

The ModScan runtime itself does not make network requests. Installing or launching ModScan through npm or npx requires npm to retrieve the package and is governed by npm's own terms, configuration, and privacy practices.

Links opened from this product website are handled by the destination website and browser, not by the ModScan command-line runtime.

This notice covers the ModScan command-line tool, not visits to modscan.kaizosha.org or kaizosha.org. Website visits are governed by the Kaizōsha website privacy policy.

If ModScan's data practices change, this notice will be updated to describe the changed release.
