Corrections Policy

If you spot an error, an outdated statement or something that is simply unclear, you can tell us through our contact page. Please include:

• The page or section you are writing about.
• The text or figure you believe is wrong.
• Any source or explanation that supports the correction.

You do not need to be an expert to report a problem. A short, specific message is more useful than a general one, and a link to a reliable source helps us verify the point quickly.

We review factual claims, calculations and statements about tipping practice. Because our methodology page describes how the calculator works, we also welcome reports that point out a mismatch between what the calculator does and what the page says it does.

Tipping is a matter of custom rather than strict fact, and practices genuinely vary. Where a report concerns a judgement call rather than an error, we may clarify the wording to make the uncertainty explicit instead of asserting a single answer.

When a correction results in a meaningful change, we keep a record of that change. The record captures what was corrected so there is a trace of the edit. Minor fixes such as a typo repair may not be recorded individually, but a substantive correction is.

Each page shows a last reviewed date. We update that date only when the page has actually been reviewed and its content has been checked or changed. We do not change a reviewed date to make a page appear more current without a genuine review behind it. If a reported error does not result in a change, the reviewed date stays as it was.

We do not add invented percentages, made-up reviews, ratings, testimonials or statistics in response to a report. If the honest answer is that a figure is uncertain or that practices vary, we say so rather than manufacturing precision.
