Just because you use WiFi in someone else's home doesn't mean that they have easy access to what you did on your Smartphone, iPad, laptop, etc.

OP be careful taking advice regarding technology on a nanny forum. You don't have to believe me but unless every page you visit is encrypted (and only things like banks, etc are encrypted. Amazon, Facebook, etc are not encrypted.) then MB can see everything you saw. All the data that ended up on you smart phone went through MBs router and she can see a page for page history.
