This site is just about your book stats. The data comes from a csv file, if you have a Goodreads account you can get that file when you scroll down on your "My Books" page towards the bottom left side, after all your shelves. There is a header for Tools. You go to import/export.
From there you export your library and don't forget to click on the tiny words underneath the export button where it says "your export dated.." because thats how you get the export to download after its been created. Not very easy to figure out if you aren't familiar.
Also, you can import that csv file into your Calibre library.
