Where are secret boards on Pinterest (laptop)?

I have created a secret bulletin board and I can't find it from the time I made it secret. Now I've been looking somewhere but have no idea. Does anyone have any idea where secret pinboards are saved on Pinterest (on the laptop)? (with pin boards it is not)

Normally you put a tick when creating the pinboard that it should be secret and when you go to your pinboard normally you will actually see it with a "lock" and under the name you gave it when you created it. And of course you have to be logged in with your own account:-)
