Project description:
"I need a lightweight Android utility that keeps a device in kiosk mode until an authorised operator unlocks it, then lets me relock the screen when work is finished. The flow is straightforward: the app boots directly into a single full-screen activity, hides the system UI, blocks the Home and Back keys, and prevents users from accessing settings or other apps. When I enter a configurable PIN (or another secure method you propose), the device should leave kiosk mode and behave like a normal Android tablet or phone. Pressing a visible “Lock” button must restore kiosk mode instantly.

Key details
• Written in Kotlin in the latest stable Android Studio.
• Target Android 12 but remain compatible down to 8.0.
• Uses DevicePolicyManager for device-owner provisioning (no root).
• Must automatically relaunch on reboot or unexpected crash.
• Clean, well-commented code so I can extend the UI later.

Deliverables
1. Signed APK ready for installation.
2. Complete Android Studio project with source code.
3. Short deployment guide explaining device-owner setup and PIN change.

If you already have experience building kiosk or lock-screen solutions, note how you will handle secure PIN storage, fail-safe exits, and any edge cases such as system updates or battery removal." (client-provided description)
