What is ClearKun?
ClearKun (クリア君) is a modern, transparent, and privacy-first Windows storage management application designed to eliminate disk space anxiety.
Traditional disk cleaners and storage analyzers often overwhelm users with cryptic system trees, raw folder hierarchies, or dangerous "one-click clean" buttons that delete files without explanation. ClearKun takes an entirely different approach: Understand first, decide with confidence, and clean safely.
Core Philosophy
1. Human-Centric Storage Clarity
Instead of throwing thousands of nested Windows system folders onto your screen, ClearKun categorizes data into intuitive concepts you actually recognize: Downloads, Media, Application Caches, Developer Artifacts, Large Files, and Unused Archives.
2. Zero File Content Ingestion
Your privacy is non-negotiable. ClearKun operates 100% locally on your computer. It analyzes only file metadata (file paths, sizes, timestamps, and attributes) via native Windows Win32 APIs. It never reads personal file contents, never inspects document contents, and never transmits your files to any cloud server.
3. Transparent Safety Classifications
ClearKun enforces a multi-tier safety model. Every item presented for cleanup is rated by risk level (Safe to Remove, Review Recommended, System Critical). Protected Windows system files, boot records, and vital system dependencies are permanently locked and cannot be removed through ClearKun.
Who is ClearKun For?
- Everyday Windows Users: Running out of space on their
C:drive with no idea what is safe to delete. - Content Creators & Designers: Managing massive video renders, raw photography assets, and Adobe/Blender cache files.
- Software Developers: Reclaiming tens of gigabytes trapped in orphaned
node_modules, Docker containers, build artifacts, and package manager caches (npm,pnpm,pip,gradle). - Gamers: Locating neglected game installations, massive shader caches, and redundant redistributable installers.
