Privacy

This is a static website. It is deliberately boring from a privacy perspective:

• No user accounts, no login, no forms that submit data to a server.
• The engineering tools (calculators, viewers) run entirely in your browser. Values you enter are never uploaded anywhere.
• The site stores a single theme preference in your browser's localStorage to remember light/dark mode. No tracking cookies are set by the site itself.
• Search runs client-side against a prebuilt index; queries are not transmitted.
• Hosting providers may log standard HTTP request metadata (IP address, user agent) for operational purposes; see your hosting provider's policy once the site is deployed.
