No. Klarity runs 100% locally on your Mac. No data is collected, transmitted, or stored remotely. There are no analytics, no accounts, and no cloud services. See our Privacy Policy for details.

Double-click any folder in the treemap or icicle view to drill into it. Use the breadcrumb navigation at the top to go back up. You can also right-click any item for options like "Reveal in Finder" or "Drill Into".

Yes. Go to Settings → Appearance → Disk Visualization and choose between Treemap (rectangles sized by file/folder size) or Icicle (stacked bars by hierarchy depth). Your preference is saved automatically.

Not permanently. Klarity can move an item to the Trash, but only after you confirm — and anything over 1 GB asks for a deliberate slide to confirm. It never empties the Trash and never touches system folders on its own, so a mistake is recoverable until you empty the Trash yourself. You can also use "Reveal in Finder" to manage files by hand.

Yes. Toggle "Show RAM" in Settings → Appearance → RAM Display Mode. Klarity will show real-time memory usage in the app. You can adjust the refresh interval in the same settings panel.

Yes. Klarity scans any mounted volume — internal SSDs, external SSDs, USB hard drives, and even network drives. Scan speed depends on the drive: internal SSDs are fastest (a full scan in seconds), external SSDs are nearly as quick, while traditional HDDs can take longer due to mechanical read speeds. For very large external drives (4 TB+), the initial scan may take a few minutes but you can browse results as they come in.

macOS marks ~/Library as hidden, and the current version skips hidden folders, so a Home scan leaves it out and the total looks small. Scan ~/Library as its own root instead: choose "Choose Folder…", press Cmd + Shift + G and type ~/Library. Scanning a folder as the root always works. Hidden-folder scanning with a Library shortcut is planned for 1.3.1. See what System Data on a Mac actually is.
