What to send

Error reports help the most when they name the tool, list the inputs you used, and say what result you expected. You can also suggest a tool you would like to see, or ask a general question about the site.

After you send a message

Messages are read by the people who build the tools. We reply to the email address you enter, so check it for typos before you send. Your message is used only to answer you and to fix what you report, as described in the privacy policy.

Many questions about how a result is calculated are answered in the "How it works" and "Frequently asked questions" sections of each tool page.
