Questions, bug reports, or a calculator you wish existed — we read every message.

Email us directly

The fastest way to reach us: [email protected]. We aim to reply within a couple of days.

Or send a message

Fill in the form below and it will open your email app with the message addressed to us — nothing is sent until you press send in your own mail client, so your words stay yours until you decide.

This form does not store or transmit anything itself — it composes an email to [email protected] in your own mail app. Prefer to write directly? Email [email protected].

What happens after you write

Your message opens in your own email app addressed to [email protected] — you review it and press send there, so nothing transmits until you say so. We aim to reply within a couple of days. Bug reports with exact numbers and steps get priority, because a reproducible bug is a fixable bug.

Corrections and suggestions

Found an error in an explanation or a worked example? Tell us the page and the exact sentence — we fix verified corrections quickly and appreciate every one. Suggested calculators go on our build list; the most-requested ideas get built first. If you are a teacher using these tools in class, we would genuinely love to hear how the lessons went and what would make the pages more classroom-friendly.

Linking to CalculateZScore

Writing a tutorial, a course page, or a blog post that mentions z-scores? You are welcome to link to any of our calculators or guides — a plain link with the page title as anchor text is perfect. If you quote a worked example or an explanation, a credit line and link back is appreciated. For anything beyond that — republishing full pages, using our content in a paid product — email us first at [email protected] and we will work something out.
