Is there an iphone 4 app that allows no one to see youre history?

I was woundering if therw is an iphone 4 app that makes it so no one can see what you do or what you searched on iphone four

On safari, click on the icon on the bottom that looks like an open book go to history and in the bottom corner, there will be a button that says clear. Press it

Just turn on private browsing on safari
Go to settings>safari and then turn "private browsing" on

  • What does it mean if someone says youre a colorful person? Last night I was with my friends and I was wearing a mint green shirt, and my friend was like "that shirt matches your mentality" and I was like uh okay what does that mean and he was just like "i don't know it just does" and then I remembered I was telling my friends I was gonna get the iphone 5c and they were saying the 5s was better, but then one of my friends said " I can see her with the 5c cause she's a colorful person" wth does that mean?
  • What app allows me to paste one photo to another? Does anybody know the name of an app for iPhone which allows you to have two or more photos, you can cut a section off of one photo and paste it to another photo? I believe there was one called "cut copy paste lite" but I can't find this.
  • Is there an iPhone photo app that allows you to draw on of a photo? After taking the photo, I want to draw arrows to show the person I'm sending the picture to what to look for in the shot.
  • Is there an iPhone app that allows you to block photos? I've tried a few and they're all complicated. They make you transport all your pictures into an app instead of locking the photos on the iPhone. I want it to lock the photos as soon as you click on the photo app. I want it to ask for a passcode to access the pictures ON the phone itself, NOT through an app. Like a feature or something? My sister always goes into my pictures when she uses my phone to talk to my dad and sees my private pictures.
