10:44 AMWhy Software Screen Privacy Beats Rigid Glass Filters
Physical tempered-glass privacy protectors solve one problem while creating three new ones. Aura Privacy gives you flexible control when and where you need it.
- × Permanently Dims Your Display: Micro-louvers cut light transmission by 30-40% even when relaxing alone in your living room.
- × Degrades Touch Sensitivity: Extra glass layer can hinder ultrasonic fingerprint scanners and swipe gestures.
- × Zero Notification Protection: Pop-up verification codes and WhatsApp previews remain visible to anyone standing directly behind you.
- × No Smart Automation: Cannot automatically engage when banking apps open or warn you when people gather behind you.
- ✓ On-Demand Digital Dimming: Slide opacity from 10% to 98% on crowded trains; turn it completely off when you're alone.
- ✓ Zero Hardware Impact: Uses Android system overlays; your screen retains 100% natural brightness, color accuracy, and touch responsiveness.
- ✓ Safe Notification Masking: Intercepts incoming SMS OTP codes and chat popups, masking the text with bullet dots (••••••••).
- ✓ On-Device AI Multi-Face Detection: Automatically triggers the privacy shield when two or more people are detected near your display.
Built for Complete Public Screen Confidence
Every feature is engineered natively for Android, adhering to strict local processing and genuine operating system capabilities.
Privacy Screen Shield & Opacity Control
Conceal your screen from casual glances and shoulder-surfers in public with a dynamic, on-demand dark overlay.
Uses Android TYPE_APPLICATION_OVERLAY with FLAG_NOT_FOCUSABLE, FLAG_NOT_TOUCHABLE, and FLAG_LAYOUT_NO_LIMITS. Digitally dims screen content while allowing full touch interaction with underlying apps.
Control: Variable slider (10% subtle tint to 98% near-blackout), Quick Settings Tile for one-tap system-wide toggle, persistent notification with instant Stop button, and a floating draggable intensity handle.
Advanced Focused Viewport Modes
Surgical privacy cutouts that reveal only the line or area you are reading while blacking out everything else.
- Reading Strip: 320-pixel horizontal clear window for reading chats line by line with a smooth vertical drag handle.
- Circular Spotlight: 480-pixel circular aperture tailored for entering bank OTPs or PIN codes with a 2D floating joystick.
- Privacy Curtain: Top-to-bottom pull-down shade with snap-to-dock points at 0%, 50%, and 100%.
Custom window overlay viewports with floating physical handles and gesture snapping.
AI Shoulder Surfer Detection (Multi-Face Peep Alert)
Automatically activates the screen shield when two or more people are detected near your screen.
Leverages the front camera via Android CameraX and Google ML Kit Face Detection at a battery-friendly 2 FPS (every 500ms). Triggers blackout when faces.size >= 2.
Control: 100% On-Device Processing. Camera frames are processed purely in local volatile RAM and immediately recycled via imageProxy.close(). No facial recognition is performed, and no photos or videos are ever captured or uploaded.
Safe Notification Cover & OTP Masking
Masks incoming message popups and banking verification codes with bullet text so bystanders cannot read them.
Powered by Android AuraNotificationListenerService. Intercepts alerts from user-selected apps and replaces the visible text with bullet characters (••••••••).
Control: Includes an inline 'Show Content' reveal toggle to inspect sensitive text safely. Automatically excludes critical alerts like incoming phone calls, alarms, and navigation.
Child Lock & Accidental Touch Blocker
Locks screen touch interactions while children or friends watch a video or browse photos.
A 100% transparent full-screen overlay that consumes touch events (onTouchEvent -> return true), preventing accidental app closures, timeline scrubbing, or unintentional button presses.
Control: Unlocked via an intentional double-tap on a glowing floating handle with haptic feedback, or through the system notification drawer.
Smart Sensor Gestures (Hands-Free Privacy)
Instant panic concealment using your phone's built-in motion and proximity hardware.
- Flip to Privacy: Turning your phone face-down or sliding it into your pocket immediately turns on the shield.
- Wave to Hide: A quick hand wave above the front proximity sensor toggles the privacy overlay.
- Shake to Hide: An intentional wrist shake toggles the shield instantly in emergencies.
Reads hardware sensor events to toggle screen concealment without touching the display.
Tailored Protection for Every Situation
Switch between surgical reading viewports, circular security apertures, and instant panic sensors.

10:44 AMChild Lock Touch Blocker
Full-screen transparent overlay that consumes all touch inputs. Hand your phone to toddlers or friends for videos without worrying about accidental touches or app closures.
Your Screen Content Stays on Your Device. Always.
Privacy tools must be held to the highest standard of technical honesty. Aura Privacy does not monitor your personal data, does not upload camera feeds, and does not sell browsing habits.
Volatile RAM Processing
Camera frames for AI face counting are processed strictly in device memory at 2 FPS and immediately destroyed via imageProxy.close().
Zero Facial Recognition
The algorithm only counts the number of detected faces (faces.size ≥ 2). It does not identify who people are and cannot detect gaze direction.
No Cloud Telemetry
Overlays, touch blocking, notification masking, and sensor gestures execute 100% locally on Android without requiring an internet connection.
Transparent Permissions
Every requested Android permission (Overlay, Notification, Camera) is clearly justified in our in-app Trust Center and Privacy Policy.
Frequently Asked Questions
Honest explanations of how Aura Privacy works, what it does, and what it does not do.
Does Aura Privacy replace a tempered glass privacy screen protector?
No. Physical tempered-glass privacy protectors use microscopic optical louvers embedded in the glass that permanently restrict horizontal viewing angles, which darkens your screen even when you are alone at home. Aura Privacy is an on-demand software overlay that digitally obscures or dims screen content only when you need it, masks private notifications, and alerts you to nearby bystanders without permanently darkening your hardware display.
Does the AI face detection take photos, record video, or recognize who is looking?
No. Aura Privacy does not perform facial recognition, does not identify people, and never records or saves any images or video. The on-device Google ML Kit algorithm only detects the count of faces in the camera frame. All processing occurs strictly inside your phone's temporary volatile RAM, and camera frames are immediately recycled and destroyed via imageProxy.close(). Zero imagery or data is ever saved to storage or uploaded to any server.
Why does Aura Privacy request the 'Display over other apps' (Overlay) permission?
Android requires the SYSTEM_ALERT_WINDOW permission so Aura Privacy can draw the digital dimming shade, reading strip, and touch blocker above your running apps. The overlay operates with standard Android system flags (FLAG_NOT_FOCUSABLE and FLAG_NOT_TOUCHABLE), allowing you to interact with your underlying apps normally while the dark shade is active.
Why does the app ask for Notification Access?
Notification Listener permission is strictly required for the Safe Notification Cover feature. It enables the app to detect incoming push notifications from selected sensitive apps (such as WhatsApp, Telegram, or banking apps) and replace the visible preview with privacy bullets (••••••••), preventing bystanders from seeing confidential verification codes or messages. Critical alerts like phone calls and alarms are never blocked.
