This page explains what information this website handles. The short version: the diagrams run in your browser, and what you type into them is not sent to us.
Your selections
Options you pick are processed on your own device. They appear in the page address (URL) so you can bookmark or share a result; anyone you send that link to will see that setup.
Saved progress
Some tools save your progress (for example, which wires you’ve ticked off) in your browser’s local storage. This stays on your device, is never sent to us, and you can clear it at any time by clearing your browser’s site data.
Analytics
We may use privacy-friendly analytics to count page views and understand which tools are useful. This information is aggregated and is not used to identify you.
Advertising
We may show ads from third-party providers such as Google AdSense to keep the site free. These providers may use cookies to show relevant ads. Where required by law (for example, for visitors in the EU and UK), we will ask for your consent first. You can learn how Google uses data at policies.google.com/technologies/partner-sites.
