Editorial standards

These standards govern calculator explanations and informational content published by Allcalcy. They are designed to make clear what a result means, where it came from, and when it should not be relied upon.

Accuracy before persuasion

We do not change an explanation to make a calculator sound more certain, useful, or authoritative than its underlying method permits. We distinguish mathematical output from real-world prediction, and we identify material assumptions close to the result or in the accompanying explanation.

Facts, models, and estimates

• Facts should be traceable to an appropriate source.
• Formulas should name the standard, publication, or convention they implement when one exists.
• Heuristics should be labelled as rules of thumb rather than official methods.
• Estimates should explain the most important reasons an actual outcome may differ.

Health, legal, and financial subjects

Pages involving consequential decisions receive additional scope, jurisdiction, source, and limitation review. We do not present a calculator as a diagnosis, legal opinion, credit decision, insurance recommendation, or personalized financial plan.

Authorship and review

Allcalcy is the publisher. We do not create fictional bylines, biographies, credentials, or expert-review claims. If a page has not been reviewed by a named qualified professional, we do not imply that it has.

Commercial independence

Advertising or affiliate relationships must be clearly distinguishable from calculator results. Payment must not determine a formula, result, warning, or factual conclusion. Sponsored material, if introduced, will be identified as such.

Use of automated tools

Software may assist research, editing, testing, and quality checks, but generated wording is not treated as evidence. Factual claims and citations must still be checked against the referenced source, and calculation changes must pass the same tests as other code changes.
