Privacy Filter: Screen Dimmer

Keep your screen private on crowded trains, in cafes, and at the office. Privacy Filter overlays a filter on your screen so people around you can't easily read it. PAID VERSION PERKS - No ads. - Set a different filter for each of the 4 styles (Style 1-4), and switch them by time and place: a pattern filter for your commute, a dark filter at night, a blue light cut before bed. MAIN FEATURES - Privacy protection Around 30 pattern filters (hearts, plaid, Japanese patterns, and more) make your screen hard to read from the side or behind. - Extra dimming Overlay a dark filter to make the screen even darker than your device's minimum brightness. Great for reading or watching videos in a dark room. - Blue light cut Warm color filters that are easy on your eyes, with color temperature presets: Candle (1900K), Lamp (2900K), and Moonlight (4000K). - Your own style Use any photo saved on your device as a filter. - Freely customize the color and opacity. ONE-TAP ON/OFF Turn the filter on and off from the Quick Settings tile or the notification area, without opening the app. It works on top of any app and any screen. NOTES - A free version with ads is also available (Style 1 only): https://play.google.com/store/apps/details?id=jp.android.poro.privacyfilter - On some OLED devices the filter effect may be limited or not displayed. - This app overlays a filter on your own screen, so it cannot make the screen hard to read only for others.
