WhaleClean is a freemium Windows 10 & 11 optimizer that replaces 5 separate tools with one clean app: no bloatware, no bundled toolbars, no dark patterns. Free tier covers the essentials: junk file cleaner and startup manager, no account required. Pro unlocks the full suite: deep clean, real-time threat scanning, driver updater, disk analyzer, duplicate finder, and privacy sweep. Built because every existing cleaner either installs adware or charges you before you see anything useful.
