Simple play, with you in charge.
Keymallow is a supervised cause-and-effect toy for babies and toddlers. It responds to curious keys, taps, and drags without accounts, ads, or third-party content.
What happens during play?
Pressing a key, tapping, or dragging creates original animated shapes and an optional gentle note. There are no levels, scores to beat, or content feeds—just immediate cause and effect.
How do I open parent controls?
Hold the top-left corner for two seconds or type parent. Play pauses before the controls open. You can change the theme, sound, and motion level, resume, or end the session.
Does fullscreen lock the device?
No. Fullscreen reduces accidental browser navigation but cannot block operating-system shortcuts. Keep play supervised. Guided Access on Apple devices or screen pinning on Android provides a stronger device lock.
What is saved?
Only local play preferences: theme, sound, energy, and an explicit motion choice. Input counts and session duration stay in memory and disappear when the page closes. Read the full privacy explanation.
Which devices work?
Keymallow is designed for current desktop and mobile browsers with keyboard, touch, or pointer input. Fullscreen and Web Audio support differ by browser; unavailable features fall back without blocking visual play.
How is motion handled?
A new visit follows the device's reduced-motion preference. A grown-up can then choose a different setting. Reduced motion uses fewer, slower shapes and removes particle spin.
