How It Works
What Shield Does on Your Child's Device

On-Device Encryption

All data encrypted locally before transmission. Your keys, your data. The server cannot decrypt child content.

Gaming Session Protection

Monitors Roblox, Discord, and Minecraft communications for grooming patterns and harmful content in real time.

Instant Parent Alerts

Severity-graded alerts pushed to your dashboard and mobile device. Only threats — not every conversation.

60-Second Heartbeat

Parents see real-time device status. If Shield goes offline for more than 5 minutes, you're notified immediately.

Pre-Filter Layer

Lightweight on-device AI screens content before network transmission. Most benign activity never leaves the device.

Auto-Updates

Shield updates automatically. New detection models and security patches delivered without manual action.
