Features include chat media cleanup, a storage map, developer cache and local AI model cleanup, app removal, duplicate files and similar photos. Ordinary file cleanup uses the Trash and can be undone before it is emptied. Docker cleanup and local snapshot deletion have separate limitations. Scanning remains free after the seven-day full trial; cleanup requires a license. See the official pages above for current details.
