Contact

YardPlanHQ has no public-office address or phone line — it is a small independent website. The honest way to reach us is by email. We read every message.

Email

The site owner has not yet configured a contact email address. This page is the intended contact route — it will show a real address once PUBLIC_CONTACT_EMAIL is set in the site configuration.

What can I contact you about?

A calculation that looks wrong — tell us your inputs and expected result, and we'll check the engine.
A density, packaging or source claim that should be updated.
New calculator ideas — suggestions genuinely shape the roadmap.
Technical issues: a layout problem on your device, or a control that doesn't work.
Guest articles or link requests are not accepted.
