BrainGuard

Is your child glued to their screen? BrainGuard helps parents take back control — without the battles.

When a child has been using their device too long, BrainGuard gently intervenes with a humorous reminder, then offers a menu of healthy alternatives:

🧠 BRAIN CHALLENGES
Five categories of stimulating questions — math, logic, trivia, vocabulary, and riddles — automatically generated and never repetitive. Kids actually enjoy these!

👨‍👩‍👧 FAMILY BATTLE
Parents set questions for kids, kids set questions for parents. A fun way to turn screen time limits into family bonding time.

👁️ EYE RELAXATION
A guided video to rest tired eyes after screen use.

🏃 PHYSICAL ACTIVITY
Suggested movements to get kids away from the screen and moving.

🏆 BRAIN POINTS & TITLES
Kids earn points for completing challenges, unlocking titles from "Beginner" to "Brain Master". Daily streaks keep them coming back.

🔒 PARENTAL CONTROLS
PIN-protected settings. Set age group (8–10, 11–13, 14–16, adult) for age-appropriate challenges. Parents can create custom questions for a personal touch.

HOW IT WORKS
BrainGuard runs quietly in the background. After a configurable period of screen use, it triggers an intervention screen. The child must complete a short brain break before returning to their device. The mandatory rest period is tracked even when the screen is locked.

PRIVACY FIRST
BrainGuard collects zero data. Everything stays on your device. No accounts, no ads, no tracking.

Available in English, 中文, and Français.

Note: BrainGuard requires Device Administrator permission to prevent unauthorized uninstallation. Accessibility Service is optional but recommended for full protection.

ACCESSIBILITY SERVICE NOTICE
BrainGuard optionally uses Android's Accessibility Service. This feature must be manually enabled by a parent or guardian. It is used solely to detect when a different app is opened during a mandatory rest period, to remind the child that rest time is not yet complete. BrainGuard does not read screen content, record keystrokes, or collect any personal data through this service.
