Advertising and privacy
The Android version is free to use and supported by a labeled banner at the top of app screens. All ad requests use child-directed treatment and G-rated content with personalization disabled. A broad age range is stored only on your device to choose privacy handling. You can continue without answering and without ads. Games and XP are never gated by watching an ad.

This Android version focuses on vocabulary learning. It does not block other apps, offer screen-time unlocks, or request Accessibility or Usage Access.

For students, families, homeschool learners, tutors, and adults who want consistent vocabulary practice.
