How your data is stored

Both tools run entirely in your browser — there's no account, no server, and nothing you enter is ever sent anywhere. Saved layouts and factory setups live in your browser's local storage.

Your data stays on this device, in this browser. It won't show up if you switch browsers or devices.
Clearing your browser's site data (or using private/incognito mode) will remove what you've saved.
No cookies, no tracking, no sign-up.
The Layout Planner can export a plan to a file and import one back in — use this to back up your work, move it to another device, or share your city with someone else.
