Can Diskern delete my files? Not directly. Scanning is read-only, and cleanup actions only move files to a quarantine folder you can review and restore from. Every move is recorded in a manifest inside that folder, so what you quarantined today is still restorable after a restart. Emptying quarantine is a separate, explicit step, and it removes only the files the manifest lists.
Does it send my data anywhere? No. Scanning, classification, and risk scoring are fully local. The optional AI narration layer is off by default and only ever explains findings — it never decides them (see the principles).
Why did Diskern mark something "review" instead of "safe"?
Verdicts come from the rules database plus local evidence.
Anything not positively identified as regenerable defaults to review —
Diskern would rather ask than guess.
Why is a file I use daily listed at all? The report shows what was found, not what to delete. Recently-accessed files get a more cautious score precisely so you notice them.
CLI or desktop app?
Same engine either way. The CLI (diskern scan <dir>) suits scripting
and remote machines; the app adds visual review and quarantine handling.
Which platforms are supported? The engine and CLI build anywhere Rust does, and their test suite runs on Linux, Windows and macOS. The desktop app is built and released for Linux and Windows; macOS builds from source and is tested in CI, but no signed macOS release ships yet.
