how to start a new document?

Hey guys,

So I'm fairly new to Lightoom CC. Atm I use it mainly for organizing work photos, not editing. I have folders and albums created for all photos that relate to work. However, I want to create a new document (or whatever it's called) to organize my personal photos. Strictly for personal photos, meaning, I don't want my work folders and albums to be available because other people use this computer for those photos, so I just want to be able to open a separate file for my personal use. 

Is there a way to do this with Lightroom CC? I suppose it's probably something you can do with Lightroom Classic since everything is stored ont the computer (I'm just assuming), but with CC?

thanks so much in advance!
