Scans run on your machine. Nothing is uploaded unless you link Cloud.

Runs on your machine
Scans and cleanups happen locally. Nothing leaves your computer unless you choose to link Kudu Cloud.
Open source, MIT licensed
Every line is public on GitHub. Cleaner rules are readable JSON, not a black box.
Scanned before it ships
Each release links its VirusTotal results in the release notes, so you can check before you install.
Review first, undo later
Preview every cleanup, keep exclusions, and restore supported settings from the Recovery Centre.

There’s a CLI

Script it with --json, schedule it with cron, or scrape it with Prometheus. Illustrative output.
