Wi-fi history and phone?

[Josh]

ok so I don't want my mom to know what i do on her wi-fi i use my phone and use it. i turned off all the gps location and etc. i clear my cookies. cache. data etc. if it matters. can she see what i look up on the wifi also, can she see what apps i go on. and before you say it no its not for that but my moms nosy and likes to tell everyone what i do and i google very embarising stuff. she isnt good with computers at all and i delete everythig i do on my phone while using the wifi and she doesnt touch my phone.
