Worried about deleting applications

[KiwiniD]

I am new to CCleaner for Mac.

 

It seems that what CCleaner does, primarily, is delete stuff. In the instructions for the Applications tab, it says, "If an application is simply listed in the Applications sections with no details, the cleaning process will typically clear out document history, visited URLs, and temporary files for that application."

 

I want to confirm that if I select one or more applications in the Applications tab for cleaning that they will not be entirely deleted and that only the sort of extra history, temporary files, etc. will be deleted.

 

Also, the instructions say that to Restore Permissions, "1. In the left-hand pane, click Tools, and then click Repair Permissions." When I click Tools, I do not see Repair Permissions anywhere. Can someone help with this?

 

Thanks
