Cyclope: Privacy Screen Filter

Cyclope turns your phone's front camera into a smart privacy filter. The moment a prying eye appears behind you, your screen dims instantly. A BODYGUARD FOR YOUR SCREEN • Real-time detection of your presence and of onlookers — entirely on-device • You alone in front of the screen: a light privacy vignette • Looking away or absent: stronger dimming • Second face detected: maximum mask immediately, with vibration and a discreet notification • Back to normal automatically as soon as the onlooker is gone BUILT FOR PRIVACY — FOR REAL • No Internet permission: the app CANNOT send data anywhere, enforced by Android at the system level • No image or biometric data is ever stored: every frame is analyzed, then immediately discarded in memory • No account, no ads, no trackers, no external analytics SMART ABOUT YOUR BATTERY • Auto-pause: screen off, phone face down, low battery, overheating • Adjustable analysis rate (5, 10 or 15 fps) • Releases the camera for your video calls and photos, then re-arms itself CUSTOMIZABLE • Filter strength and detection sensitivity on 5 levels • Configurable inattention delay (1 to 5 s) • Quick Settings tile: toggle without opening the app • Glasses-friendly detection • Local statistics: sessions, alerts, protected time • Available in English, French, German, Spanish and Italian TRANSPARENCY A software filter cannot replicate a hardware viewing-angle privacy filter: the dimming applies to the whole screen, for everyone. Cyclope relies on behavioral detection — the same approach as the built-in "Privacy Screen" features of some manufacturers — to react before an onlooker has time to read. PERMISSIONS USED • Camera: face detection, processed locally, never recorded • Display over other apps: drawing the filter on top of your apps • Notifications: discreetly alerting you when an onlooker is detected Minimal by design. Your screen looks at you only.
