Corrections and questions → hello@calculatorsking.com
Or email hello@calculatorsking.com
Write to Calculators King when a formula label is unclear, a statutory figure needs an update, or a page is behaving badly. The mailbox is hello@calculatorsking.com. The form on this page sends the same mailbox a plain-text message with your name, your email, a topic, and whatever you type. We use it to reply. We do not use it as a newsletter signup.
Say which page you mean by pasting the URL. If a result looks wrong, include the inputs that are safe to share and the figure you expected. Do not send medical record numbers, full card numbers, or copies of identity documents. A question about the mean, a mortgage formula, or a maternity-pay model can be asked without those. If the form fails, the page will say so and the email address above still works. Shared hosting sometimes blocks automated mail, and the form is built to admit that instead of pretending the message vanished into a successful silence.
We read corrections with the editorial rule in mind. If the convention on a page is a real convention and it is labelled, we may keep it and clarify the sentence. If the arithmetic is wrong against a known anchor, we change the page. If a rate such as statutory maternity pay moves, tell us the date it moved and the source you are looking at. The field on that calculator is already editable so a reader is not stuck waiting for us.
This is also the right door for privacy requests. If you want contact messages deleted, say so from the same email address you used to send them. We do not operate user accounts, so there is no password to reset and no dashboard of saved calculations. Anything still sitting in a browser tab is on your device.
Please write in ordinary language. A short note with one URL is more useful than a demand to change fifty pages at once. We answer as quickly as a small editorial desk can. The rest of the site keeps working while a message sits in the queue, because the worksheets do not depend on the mailbox.
If you are writing about a health, pay, or dosing page, you still should not include a patient's name or a colleague's salary. Describe the formula and the public inputs. We can check a mortgage example with round numbers. We cannot and should not receive a real personnel file in order to see that a pro rata fraction was unclear. The same restraint applies to screenshots. Crop them.
The form asks for a topic so the inbox is sortable: a correction, a formula question, a privacy request, or something else. Pick the closest. A privacy request should say whether you want a copy or a deletion. A correction should say what you think the page should show and why. A formula question can be as simple as which page divides by n and which divides by n minus 1. That last one is already answered on the variance page, and you are still welcome to ask it.
We will not reply to messages that ask us to pretend a result is official, to write a medical dose, or to bypass a game. Those are outside the desk. We will reply to messages that make the public reference more accurate. If you do not get a reply, the usual reason is that the host rejected the mail, which is why the address is also printed in full on this page and in the footer of every worksheet. A second useful kind of note is a clash between two of our own pages. If the mean page and the descriptive statistics page ever disagree on the same list, that is an error even if both explanations sound calm. Send the list. We would rather see five numbers than a general complaint that the site feels wrong.
Office hours are not posted because the desk is not a call centre. The site itself does not depend on a reply. Every calculator that is already published keeps working if the mailbox is quiet for a day. If your question is which tool to open, the category pages and the FAQs are the faster answer, and they do not require anyone to be awake. Please do not send the same note several times in an hour. Duplicates make the real correction harder to see. One clear message with the URL is enough, even if the confirmation banner never appears and you also used your own mail programme as a backup. A second copy sent the same afternoon does not make the first one more accurate. It only makes the queue longer, and a longer queue is slower for the person who included the URL the first time.
When you write from a school or a newsroom, say so in one line. Attribution requests and classroom packs are easier to answer when we know the context. We still will not invent a personal diagnosis or a payroll ruling, and we still need the URL of the page you mean. A clear note beats a long one.
To hello@calculatorsking.com. You will see a confirmation if the server accepts it, or a clear failure if it does not. The email address still works when the form does not.
The page URL, the inputs that are safe to share, and the result you expected. Leave out medical record numbers and payment cards.
No. A message is a message. It is not a mailing-list opt-in.
There are no accounts and no passwords. Calculator values live only in the browser tab you already have open.
As fast as a small desk can read the note. A single URL and a specific figure are the notes we can answer first.
