What this site stores
Effective September 6, 2026. Maintenance notes and arcade best scores use localStorage in your browser. They are not sent to our server or synced across devices. Clearing browser data removes them.
You can export the maintenance log as JSON and delete individual notes or the entire log. Clear arcade scores on the game page. Calculator inputs stay in page memory and reset when you leave or reload.
