If you use someone else's WiFi can they see what you do on your device?

I used to attend a school where we had to have an iPad. I was curious if using their WiFi they could see what apps I used or what I was looking at while using and also when not using their WiFi. I know it seems like a weird question, but people say things about using other's WiFi and how they can see your information. Thank you.

My son is seven and his aunty is ten.every toy that my son wants she goes out with her dad and he buys it for her.that she never plays with?

How do i deal with this. Its becoming ridiculous. Like full on boys toys she brings home. I can't afford to go out and buy most of it. But she ll come home with it all, ipads, ipods, phone, tablets, ds… It upsets my son but more for the fact that she doesn't play with it and refuses to let him. How do i deal with this. My child doesn't expect stuff but i just feel like he is going to grow up and think that i did nothing for him. How do i deal with this.thanks
