What is the difference between the free version and the registered...

The free version handles everyday cleaning -- temporary files, browser caches, system junk, and privacy traces. It also scans for duplicate files and shows you exactly how much space they waste.

Registration unlocks these additional features:

• Duplicate File Cleaning -- Remove the duplicate files the scanner already found (most users recover 5-50 GB)
• Scheduled Automatic Cleaning -- Daily, weekly, or monthly cleaning on autopilot
• Cleaning Profiles -- Save and switch between named configurations like "Quick Clean" or "Deep Privacy Clean"
• Custom Cleaner Rules -- Define your own file and folder targets using patterns
• Secure File Shredding -- Overwrite deleted files so they cannot be recovered (1-pass or 3-pass)
• HTML/PDF Cleaning Reports -- Export reports for IT documentation or compliance
• Splash-Free Exit -- The brief closing splash screen is removed

Every license tier unlocks the same features. There are no "Pro" vs "Premium" confusion levels. See the product page for the full feature comparison.
