Privacy notice

Design information

When you generate a custom design, your entered specification is sent to this app’s server to perform calculations and return drawings and instructions. The application does not save submissions in a database or send them to an AI provider. Avoid entering private or confidential information in project names.

Browser state and downloads

Form values, generated results, and checklist selections are held in the current page’s memory. They reset when the page is reloaded. Downloaded files are saved by your browser to your device.

Technical requests

The hosting infrastructure processes requests to operate and protect the service and may maintain technical logs, including IP addresses and request metadata. When a tutorial check runs, the server requests the listed Arduino or Adafruit pages. Design inputs are not included in those tutorial requests.

Advertising and analytics

Google AdSense code is installed to connect and review this site for advertising. Loading that code sends a request to Google, which may process technical information such as your IP address, browser information, cookies, or other identifiers under its policies. No manual display ad unit or separate analytics script is configured. Ad availability depends on Google approval and account settings. Required consent messages must be configured before serving ads to audiences for whom consent is required.

How Google uses information from sites that use its services

External links

Opening a tutorial or other external link takes you to a third-party service with its own privacy practices. This app does not control those services.
