Privacy Filter Free

A "Privacy filter" app has been created to guard your privacy from the prying eyes of others.
Guard from prying eyes using filters with cute designs.
Recommended for people who feel uneasy about prying eyes when on a train, or other places where you may notice prying eyes.
The black filter greatly reduces screen brightness in dark places.
With one tap of the widget, that can be arranged anywhere on the screen, the filter can be switched ON or OFF.
The transparency of the filter can be freely set, making it possible to adjust to a level that allows easy viewing for you.
