Just asking

Is it true that your internet router thingy can be open like they can see the history and even if youre in a incognito mode they still can see it.
I've been having nightmares abt this
Because my brother and cousin are talking about opening it like sht im losing my mind like everytime i walk pass by them theyre talking abt this.
Also how to delete it, thankss (╥_╥)
