Private Browser Calculator S

This is a browser to protect your privacy. Its icon and name are like those of a calculator. And It starts as a calculator at first. (Off cause, it does work as a real one.)

When PIN is input to a calculator, Browser Mode starts. It’s a custom browser inside this App, Not Safari. Your history and a bookmark can't be accessed from other apps. When you turned off screen or return to a home screen, the Browser Mode finish automatically.
