How this works

Every tool on this site writes its numbers to this browser's storage and registers itself here the first time you open it. This page just reads what's already been registered — it doesn't talk to any server. That also means it only knows about tools you've opened in this browser; a different browser or device starts empty. Use "Export all" any time you want a backup file covering every tool at once. The Plan Audit at the top reads the same saved numbers and checks the tools against each other. It never changes them.
