Eight tools that protect your child's Android phone — from the network layer to the screen they're reading. All managed behind a PIN only you know.
Blocks websites at the DNS level using a local VPN — not a browser plugin your child can uninstall. Works across every app and every browser on the phone.
Network-level · All apps coveredBlock certain websites only during school hours or homework time. Allow them on weekends. Set a schedule once and it enforces automatically every day.
Per-site schedulesCut all internet access during set hours. No exceptions — every website and every app loses connectivity during the lockout window. Perfect for bedtime.
Full internet cutoffUses Android accessibility services to read on-screen text and flag harmful content in messaging apps. Parents review color-coded alert cards — red for urgent, yellow for caution.

"I'm a teacher and a father of four in Japan. I built Layers Guard for Chrome to protect my students, but then I realized — my own children's phones needed the same protection. So I built this app for them. No subscription traps, no data harvesting. Just a parent protecting their kids."
Peter Hoang — Teacher & Father of four, Japan
