## What is TraceLock?

Turn your iPhone or iPad into a tracing lightbox: import an image, position it, lock the screen against accidental touches, place paper on top, and trace.

TraceLock is intentionally focused. It solves one specific job with no account, no ads, and no cloud photo uploads.

• Import an image from Photos
• Convert it to sketch, outline, comic, black-and-white, or high contrast
• Scale, move, rotate, and mirror it to fit your paper
• Lock the canvas so paper and palms do not move the image
• Keep the display awake and use full brightness while tracing
• Hold for two seconds to unlock safely

Photo processing happens on your device. TraceLock does not collect personal data.
Try every feature with total peace of mind.
