About this app

BlinkRoll is an Android accessibility tool that turns deliberate eye blinks into vertical scrolling, moving long screens up or down in compatible apps. It helps users with upper-limb motor impairments navigate apps and web content without repeated taps or swipes. The front camera recognizes eye blinks and sends a vertical scroll action to the current screen.

Key features:
- Short close (default): close briefly, then open, to move in the configured direction each time
- Short or long close: close briefly for the configured direction, or hold longer for the opposite direction
- Long close: hold closed longer, then open, to make one larger move in the configured direction
- Primary direction and movement distance controls
- Session distance shown for blink-controlled movement
- A small indicator that shows the current status
- Start and stop scrolling from notifications and Quick Settings
- Automatic pause when the screen is off or locked, and optional no-face auto-stop
- Camera frames are processed only on the device and discarded after analysis
- Current-screen scrolling through Android Accessibility Service

Privacy:
BlinkRoll does not send or store camera frames, face images, or face landmark data on a server. Eye blink detection runs on the device, and input frames are discarded after analysis.

Access time:
On first install and after access expires, finishing one rewarded ad grants 24 hours of access from completion. Remaining time continues to elapse while the app is closed, in the background, or the screen is locked. Canceling, not completing, or failing to load the ad does not grant access time.

How to use:
1. Allow camera and notification permissions.
2. Turn on BlinkRoll · vertical scrolling in Android accessibility settings.
3. If no access time remains, finish one rewarded ad.
4. Start with Short close. Switch to Short or long close or Long close when needed.
5. Tap Start scrolling, move to another app, and close and reopen your eyes once.

Safety:
BlinkRoll is not a medical, diagnostic, treatment, or vision protection app. Do not use while driving, walking, or performing dangerous tasks. Stop scrolling and rest if your eyes feel tired or uncomfortable. Recognition accuracy may decrease in very dark environments, strong backlight, or unstable camera conditions.
