Under the hood.

CleanDeck was built to be completely transparent. We don't hide our algorithms behind a shiny button. Here is exactly how our engine works to keep your Mac fast and safe.

Deep System Scan

CleanDeck doesn't just look at standard caches. It scans developer environments, hidden temp directories, and abandoned app states, mapping the entire macOS filesystem in seconds using native APFS optimizations.

Deterministic Classification

Every single byte is run through our deterministic classification engine. It separates known SAFE artifacts from ambiguous USER data, enforcing strict PROTECT invariants around your system roots.

Trash-First Deletion

Unlike other cleaners that permanently obliterate files via 'rm -rf', CleanDeck routes all actions through the macOS Trash API. You always have a native, OS-level undo.

Container & Dev Tool Isolation

We built specialized logic for developers. CleanDeck understands the difference between a stale Docker cache and an active volume, or a broken NPM module and a required global dependency.

Local AI Insights

For complex Review candidates, CleanDeck leverages on-device Local LLMs to explain what the file is, why it was flagged, and the risk of removing it. Zero data leaves your Mac.

Immutable Action History

CleanDeck acts like a version control system for your storage. Every single file moved is logged in a persistent Action History, giving you a perfect audit trail of all operations.
