Editorial policy
How CalculateFox pages are written and reviewed, how automation is used, how corrections work, and why advertising never influences a calculation.
Who writes the pages
Every page is written for the person who will use it, not for a search engine. That means starting from the question they typed, answering it, and then showing the working. Pages are reviewed against a checklist before publication: is the native keyword the slug, title and heading; is there a worked example; are the edge cases named; does the calculator handle empty and invalid input.
Review and dates
Pages that touch health or money name a reviewer and a review date, because those topics can affect someone’s decisions. Other pages carry a “last updated” date. That date changes only when the content materially changes — not when a page is re-saved or re-deployed.
Use of automation
Some drafts are produced with AI assistance and then edited. We say so because you would reasonably want to know how a page was made.
What automation is not allowed to do here:
- invent an author, a reviewer, a headshot or a credential;
- state a medical, tax or legal rule without a source;
- publish a page that has not been checked against the method on the “How we calculate” page.
Every calculator’s arithmetic is covered by tests, so a factual error in a formula fails the build rather than going live.
Corrections
If you find an error, contact us with the page, the inputs and what you expected. We fix the page, note the change, and move the review date. If a page cannot be corrected quickly, it is unpublished until it can be — a wrong answer is worse than no answer.
Advertising
The site is funded by ads. Advertising has no influence on what a calculator returns, on what a page says, or on which tools exist. Ad slots are labelled, kept below the result panel, and never placed between an input and its answer.
Language and localisation
Each language version is written for its own market rather than machine-translated from English. Formats follow local convention: number separators, date order, currency, week start. Where a rule is country-specific, the page states the year it applies to.
