Contact the site owner
The official contact address is contact@exactsizetools.com. Use it for site feedback, accessibility questions, and general enquiries.
There is no contact form. Reliable form delivery would require a properly secured mail service, validation, rate limiting, and spam controls that this static site does not use. Do not send passport photos, signatures, identity documents, PDFs, passwords, or other sensitive files by email.
What to include
For a site issue, describe the page, device/browser, and the visible error without attaching personal files. If a tool result is unexpected, include the non-sensitive settings you selected rather than the source document.
Email messages are handled through the owner's mailbox. This site does not make a claim about the mailbox provider, retention period, or response time.
