Trust & transparency
Editorial policy
ONLINTools publishes practical, calculation-led guides. Our standard is simple: the reader should be able to understand the reasoning, reproduce the example, and inspect the sources.
Search intent first
Every guide answers a defined question and connects to a calculator that helps the reader act on the answer.
Calculations are reproducible
Worked examples state their assumptions and are recomputed before publication.
Sources are visible
Health, finance, standards, and technical claims link to primary or authoritative references whenever available.
Limitations are explicit
We identify uncertainty, exceptions, and situations where a calculator cannot replace professional judgment.
Updates are dated
Material changes update the visible modified date. Corrections are made as soon as a verified issue is found.
No paid conclusions
Advertising does not determine calculator results, article conclusions, or tool recommendations.
Corrections
If you find a factual, formula, accessibility, or citation problem, email [email protected] with the page URL and a short explanation. We review reproducible issues and update the article when warranted.
