How did she find my history after it was deleted?

A few weeks ago my mom took my phone from me and went through it, she has a friend that's son works at one of those stores where they sells phones and stuff. Anyways back to the story the lady showed my mom a trick on how to pull back up my history and it didn't require a computer because she did it on my sisters phone and I was only a few feet away. Can anybody tell me how the lady might of brought back my history and yes this did happen on a IPhone.

When the NSA and the Illuminati start working together there's no limit to the fun they can have with your data. Oh, also Google and Neiman-Marcus were probably involved. And Bill Clinton.

It all gets logged. Deleting history doesn't fully hide it. Only stops the casual user from looking at it. Also probably logged at providers level

Start asking your geek friends then learn how to block the search. Then teach your sis and have a friend for life.

Haha… Perhaps the question should be, "How do I use my phone responsibly so that I don't have to worry about my browsing history?"
