CamBlock

This app helps visitors establish a temporary secure session on their iPhone while entering the secure facilities through a QR-guided check-in and verified check-out.

CamBlock helps visitors establish a temporary secure session on their iPhone while entering designated secure facilities.

Visitors begin by scanning an entry QR code provided by the facility. The app then guides the user through Apple's Screen Time authorization process to enable a temporary secure session on their own device for the duration of the visit. Once the visit is complete, the secure session ends through a verified checkout process.

CamBlock uses Apple's public Screen Time frameworks (FamilyControls, ManagedSettings, and DeviceActivity) together with explicit user authorization. The app does not use Mobile Device Management (MDM), configuration profiles, private APIs, or location tracking.

Key Features

• QR-based visitor check-in

• Guided secure-session setup

• User-authorized temporary device restrictions during an active visit

• Verified exit-code workflow

• Force-exit request and approval workflow

• Push notifications for exit request updates

• Secure restoration of normal device functionality after checkout

CamBlock is designed for organizations that require visitors to follow a temporary secure-session workflow while accessing designated facilities. All device restrictions are initiated only after the user explicitly grants authorization through Apple's Screen Time interface and remain under user control.
