Scope, limits & privacy
Four separate captures are placed into a 2×2 grid or vertical strip. Each collage cell is 480×360 with proportional contain fitting, so unused areas use the selected border colour. Capture spacing is approximate active-page timing, and the camera stops after the fourth frame. After capture, adjust layout, gap or border and choose Rebuild collage to reuse those four photos. No face detection or cloud gallery.
HTTPS or localhost and browser camera permission are required. Facing direction and dimensions are preferences; delivered settings are shown. No camera history or uploads. Hidden tabs stop capture, and Reset, switching or exit releases captures, workers, URLs and tracks.
