Where does sqlite file get stored on Mac?

I've linked libsqlite3.dylib in my Xcode 6.6.1 application. I'm not using Core data, I'm using FMDB. Where can I find the .db or .sqlite file that gets created when my app is running?

I am pretty new to using a Mac, but I believe I searched everywhere on my machine using Finder and couldn't find any *.db or *.sqlite files. When I run the app, it's retaining data between executions, so I know it's getting saved somewhere... but where?
