Write
There is no public inbox on the site yet. Ads and analytics stay off until there is one, because both need a dated privacy policy and an address people can actually write to. The form still prepares the note so you can copy it; when an address exists, it will be listed here and the same form will open your mail app.
Calculator requests
If a calculator is missing, say what it should compute, who it is for, and which official table it should use if you know one. The closest page already on the site helps. A request is read. Building it is a separate decision. There is no queue you can check, and no promise of a date.
Complaints about the product (a page that will not load, a ZIP lookup that hangs, copy that contradicts the numbers) go in the same form. Pick Something broken. Product complaints and wrong figures are different notes. Mix them and the Method line gets lost.
Wrong figures
Open Technical details under the answer and copy the two lines there into the form.
- The page URL
- The Method version
- The Data snapshot id, or “Manual inputs / fixed rules” if that is what it says
- What you typed, what the page showed, and what you expected
- A title, period, and link for the official table you are comparing, if you have one
Do not send paystubs, tax returns, account numbers, Social Security numbers, or medical records. The calculators do not need them, and neither does this form.
What this is for
A formula that does not match its worked example. A stored dataset that does not match its hash. A source, period, or geography labelled as the wrong one. A page still showing an older figure as current after the provider has published again. A calculator this catalogue does not have. Copy or layout that gets in the way of reading a result.
Personal tax, lending, medical, payroll, or travel questions belong with the official source named on the page, or with someone licensed to take that on. Common questions about what a result is, where the data comes from, and what the site stores are on the FAQ.
After you send it
A report with the Method and Data lines can be checked against the tests and the stored snapshot. If the engine is wrong, the Method string changes. If the data is wrong or stale, the Data id changes. Older results keep the strings they printed, so a past screenshot still points at that copy.
A calculator request is not a ticket. If it is built, it shows up in the catalogue with a Method version of its own. There is no promised response time. A complete note gets read. A screenshot with no version usually cannot be checked.
