Use this Contact PDGPT page to get in touch with the team behind PDGPT. If a calculator gives a wrong result, a page does not load, or you have a suggestion for a useful new tool, we want to hear about it. The form below is the only contact route on this site, and it sends your message to us without requiring an account or a sign-up.

Contact PDGPT: Contact Form
Please fill in the form below. Your name and email address help us reply to you, and your message should describe the issue or idea as clearly as you can. If you are reporting a problem with a calculator, please include the name of the tool, the numbers you entered, and the result you expected, so we can reproduce the problem and fix it.
Contact PDGPT: What to Write About
You can use the Contact PDGPT form for several kinds of messages. Report a calculator that does not work, a formula that looks wrong, or a worked example that does not match the result. Suggest a new calculator that would be useful for everyday life, study, or work. Tell us about a page that is hard to read on your phone, a link that does not work, or wording that is unclear. You can also ask a general question about how PDGPT works.
Please do not send personal information that we do not need, such as passwords, bank details, or identity documents. The calculators on PDGPT never ask for such information, and we never need it to answer a question or fix a tool. If you are unsure whether a detail is needed, leave it out and describe the problem in general terms instead.
Contact PDGPT: After You Send a Message
After you submit the form, you should see a confirmation message on this page. That means your message was sent. We read every message we receive, and we aim to reply as soon as we can. Because PDGPT is a small, free site, replies may take some time, and we cannot promise a reply by a particular date. If your message is about a broken tool, fixing the tool is often the reply itself, and you will see the corrected page on your next visit.
If you do not hear back, please check that you entered your email address correctly, and try again with a clear subject line. A short, specific message is easier to answer than a long one, so please focus on the tool, the problem, and what you expected to happen.
Contact PDGPT: Your Privacy
The only personal information in a contact message is what you choose to write in the form, normally your name, your email address, and your message. That information is used only to read and reply to your message. It is not sold, and it is not used to build a profile about you. Our Privacy Policy explains this in more detail, and our cookie notice gives you a simple choice about cookies on this site.
Before you write, you may also find the answer on the About PDGPT page, which explains what PDGPT does, or on the tool page itself, which shows the formula and worked examples. If you still need help, use the form above, and return to the PDGPT homepage to keep using the free calculators. For background on how contact forms work on WordPress sites, see Wikipedia’s article on WordPress.
Thank you for using Contact PDGPT. Your message helps us keep the calculators accurate, clear, and useful for visitors in the United States, the United Kingdom, and Canada. We appreciate every report, suggestion, and question, and we use them to decide which tools to add next and which pages to improve first.
