> Nijia is a macOS storage analysis and cleanup application for Apple Silicon and Intel Macs running macOS 13 or later. It combines disk and folder analysis, reviewed cleanup, developer workspace inspection, local file-organization proposals and system monitoring.
Scanning does not delete files. Cleanup requires review and confirmation before selected items move to Trash. Emptying Trash requires a separate irreversible confirmation. File-organization proposals stay local and require confirmation before files move. All features are available in a 7-day free trial started in the app, with no payment card or automatic charge. A paid Pro license is required after the trial; current plans and checkout availability are on the pricing page.
Storage scans and organization proposals run locally. Website analytics, purchases and license activation have separate data flows documented in the privacy policy. Comparisons are published by Nijia and disclose their evidence and limitations.
