CORRECTION PROCESS
Calculator corrections and review policy
Answer Atlas is built around useful, checkable calculations. If a calculator, converter, explanation or accessibility behavior looks wrong, this page explains how to report it and how we review it.
Last reviewed: 28 August 2026.
What to send
Email editorial@answeratlasglobal.com with the calculator name, the value you entered, the result shown, the result you expected and a reliable reference if one exists. Do not send account numbers, identity numbers, medical records, passwords, card details or other sensitive personal information.
What we review
- Formula or conversion-factor accuracy.
- Rounding behavior and displayed units.
- Invalid, zero, decimal, negative or over-limit input handling.
- Whether the wording could create unsupported tax, legal, financial, medical or safety claims.
- Accessibility, keyboard, mobile and right-to-left layout behavior.
- Privacy behavior, including whether calculator inputs or results remain local.
How fixes are accepted
A correction is accepted only after the relevant source, formula and regression tests support it. Arithmetic changes must be deterministic and must pass known-value checks before release. Payment, advertising or sponsorship requests cannot change formulas or calculated results.
Local-rule limits
Some calculators depend on local laws, tax rules, health guidance, construction standards or regulated financial assumptions. Those pages must avoid strong country-specific claims until the correct source, disclaimer and review standard are ready.
