Can my parents spy on my internet history?

I've got my own PC, and also my own tablet. And I use the house's wifi. They don't have access to my PC or tablet, or google account etc.. Can they see my internet history any way, such as on the wifi admin account or something? Thanks
Update: Thank you for the answers so far, is there any way to see if they have been looking at it? Also is there any way to hide it, such as incognito tabs?
