## NTN SafetyOne Description
Safety Zone helps you take control of your screen time by blocking distracting apps, setting focus schedules, and building healthier digital habits — all 100% on-device and private.

• Block Distracting Apps
Choose which apps to block with Apple's built-in app picker. A shield overlay appears when you try to open blocked apps, keeping you focused.

• Focus Schedules
Create recurring schedules (Work, Study, Sleep, Morning Routine) that automatically block selected apps during specific hours and days of the week.

• Focus Sessions
Start timed focus sessions — 15, 25, 45, or 60 minutes — with a visual countdown timer. Stay on track and see your progress in real time.

• Strict Mode
Enable a 5-second delay before unblocking apps, helping you resist the impulse to open distracting apps.

• PIN Lock
Set a 4-digit PIN to prevent accidental or impulsive changes to your blocking settings.

• Quick Presets
Get started fast with built-in schedule presets for Work, Study, Sleep, and Morning Routine.

Safety Zone uses Apple's official Screen Time APIs (FamilyControls, ManagedSettings, DeviceActivity). All data stays on your device — nothing is sent to any server. No analytics, no tracking, no ads. Your digital habits are your business.
