Get in touch
Found a bug, spotted a maths mistake, or have an idea for the next tool? We would genuinely like to hear it. There is no form to fill in and no account to create. One email address, read by real people.
Email us
Write to support@graphingcalculator.us for anything at all. To help us reply quickly, it is useful if you include:
- What you were doing, for example the equation you typed or the tool you were using.
- What you expected to happen, and what happened instead.
- Your device and browser if it looked like a display or layout problem, such as Chrome on Android or Safari on iPhone.
What to reach out about
- Bug reports. A curve that draws wrong, a button that does nothing, a layout that breaks on your screen.
- Maths corrections. If a result or an explanation in a calculator guide looks off, tell us. Accuracy matters more to us than being right.
- Feature ideas. A function you wish the graphing calculator supported, or a tool you would like us to build next.
- Feedback. Anything that made the site easier or harder to use.
Response time
GraphCalc is a small project, so replies are not instant, but every message is read. Please allow a few days. If your note is a bug report, a short, clear description is the fastest route to a fix.
Why there is no contact form
We keep the site free of accounts and databases, which is also why your calculations never leave your browser. A contact form would need somewhere to store submissions, so instead we use a direct email link. It is simpler, and it means your message goes straight to us with nothing collected in between. You can read more in our privacy policy.

Or just start graphing
No account, nothing to install. Open the calculator and plot your first function.
