Little Painter is a finger-painting app for toddlers that keeps the phone locked to the canvas, so little artists can draw freely without calling anyone, opening the camera, or wandering into your email.

Features:

* Kid-proof lockdown: uses Android screen pinning to keep the child inside the app, with system bars hidden and edge gestures suppressed while painting
* PIN-protected exit: a hidden long-press zone (top-right corner, 2 seconds) asks for a parent PIN before unlocking the phone
* Simple painting tools: 8 colors, adjustable brush size, eraser, and fun stamps (star, heart, flower, snowflake) with a long-press picker
* Clear with undo, for accidental canvas wipes
* Optional gentle screen-time reminder: an hourglass fades in after a configurable time, without ever interrupting the child
* No ads, no tracking, no internet permission; the exit PIN is stored only on the device, salted and hashed
* Available in English and Spanish

Note: there is no PIN recovery. If the exit PIN is forgotten, clear the app's data from Android Settings to reset it.
