How do I get the tool to remember my cutter size?

Sign in, then any Settings change auto-syncs to your profile (debounced ~1s after the last edit). Next time you load the tool on any device while signed in, your settings come along. Signed-out, settings live in this browser's localStorage and won't follow you.

If the cutter size keeps reverting on reload — that was a bug we fixed mid-May 2026. Hard-refresh the page (Ctrl+Shift+R / Cmd+Shift+R) to clear cache.
