The Clean function was carefully designed to only remove data that is truly dispensable, such as system caches that can be easily replaced, or already installed APK files. If you are concerned, you can define the exact types of items that are cleaned in your Cleaning settings and also turn the Clean Check option on to review items before they are deleted.
