The app

Dysky reads folder listings on your PC to show how much space things take. It never changes, moves or deletes files.

It collects nothing and sends nothing. It has no telemetry, no accounts and no network access: the window's security policy does not allow connections to the internet.

Your settings (theme, chart shape, size units) and the window's size and position are saved only on your PC. If Dysky crashes, it writes a short crash log to its own folder in %LOCALAPPDATA% so you can attach it to a bug report. It is never sent anywhere by itself.

This website

No cookies, no ads and no tracking. The demo runs on sample data inside your browser and cannot see your files. The theme you pick here and the demo's settings stay in your browser's local storage.

The site is hosted on Firebase Hosting by Google, which processes standard request data such as IP addresses to deliver pages and keep the service secure. Downloads come from GitHub Releases, run by GitHub. The Microsoft Store page is run by Microsoft under its own privacy statement.
