Veilleuse turns your phone into a simple night light, with no ads and no trackers. Features: * Two light sources: the camera flash, or the screen with an adjustable warm tint. * Adjustable duration before automatic shutdown (1 to 120 minutes). * Instant or progressive (fade) shutdown, with adjustable fade duration. * Fully pure-black (OLED) interface, to save battery and avoid glare. * While active, the screen goes fully dark; a single tap brings back the controls (remaining time, Stop button). * Once the timer ends, the app closes itself so the phone can go to sleep normally. Settings screen: * Time display format: compact, detailed, or HH:MM:SS. * UI accent color: palette of hues and white, with a slider to darken it. * App language: 26 languages available, independent of the system language.
