Corrections Policy

Report a problem

Send the page URL, the disputed statement or result, your evidence, and the expected correction through the contact page.

Our process

We reproduce calculator issues, verify cited material against the primary source, assess translations separately, and prioritize errors that could affect safety or purchasing decisions.

How corrections appear

Minor spelling and formatting changes may be corrected without a notice. Substantive factual, formula, or safety changes receive an updated modification date and a visible correction note when necessary.

Response standard

Every credible report is reviewed on its evidence. We do not remove accurate information because it is inconvenient to an advertiser, retailer, or other commercial party.
