Where does chrome store LocalStorage on my computer?

Question

i want to get the localstorage of a particular website. i need to get some keys' value that appear only when device-view button is clicked and it is mobile-view. I went to C:\Users\admin\appdata\Local\Google\Chrome\User Data\Default\Local Storage\leveldb but found nothing interesting . i used an ldb viewer but still couldnt understand where to get the key value from. for example i want to see the value of key 'numberofcats' from localstorage of "wth.mycatwtf.com"
