OhhPro Fusion - For Signaller

Ohhpro Technologies Pvt. Ltd.

About this app

OhhPro Fusion – For Signaller is a secure, single-launcher kiosk app designed to lock users into a focused, task-specific interface. Ideal for professional environments such as field operations, logistics control, signal monitoring, and public kiosks, this app ensures users stay restricted to a single screen, reducing distractions and preventing unauthorized access to other parts of the device.

Whether you're managing a fleet of devices used in transportation systems, industrial sites, or enterprise workflows, OhhPro Fusion transforms any Android device into a secure terminal. Once activated, users can only interact with the designated screen — with no multitasking, app switching, or system navigation.

🔒 Key Features
✅ Single Launcher Mode

Locks the device to a single screen or app to maintain a controlled work environment.

✅ Kiosk-Mode Ready

Turns any device into a restricted-use terminal for POS, field operations, signaling stations, and more.

(See “AccessibilityService Disclosure” below.)

✅ Auto-Start on Boot

Auto-launches after restart to maintain a secure locked state.

Smooth performance on both modern and older devices.

🛠️ Why OhhPro Fusion?

Standard Android devices allow users to switch apps, open the power menu, access settings, and multitask — which becomes a security risk in critical operational environments.
OhhPro Fusion eliminates that risk by enforcing a controlled, single-screen, distraction-free workspace.

⚙️ Easy Setup

Install OhhPro Fusion

Set it as the default launcher

Select the target screen/activity to lock the device

Compatible with Android 6.0+ and does not require root.

🔐 AccessibilityService Disclosure (Required by Google Play)

OhhPro Fusion – For Signaller uses the AccessibilityService API only to support kiosk-mode security features by restricting access to the power menu and detecting specific system UI events. This ensures users cannot exit the locked workspace or shut down the device unintentionally during operation.

The AccessibilityService is used only for:
• Detecting power-menu and system UI events
• Assisting in maintaining kiosk lock mode
• Preventing accidental exits or shutdowns during workflow operations

The app does NOT:
• Collect or share personal data
• Record audio or calls
• Control the device without user consent
• Modify system settings
• Perform hidden or unauthorized actions

It is required solely to provide a secure, uninterrupted operational environment.
