What we publish
The home-page scientific calculator runs in the browser. Specialist tools enter the public catalog only when their exact formula versions, source scope, reference examples, validation boundaries, and current engineering tests are explicitly bound by a production authorization. A site-owner authorization is disclosed as such and is never called independent expert, QA, editorial, or legal approval. Unbound work stays outside production.
The calculation methodology describes the release gate, while the editorial policyexplains source selection, corrections, and versioning.
Review and corrections
Software verification does not replace subject-matter review. Higher-stakes tools without a published qualified reviewer remain estimates for general information, and their results must be independently checked before a consequential decision. Reviewer requirements are documented on the expert review page.
Suspected errors can be reported through supportusing synthetic or redacted inputs. Material formula or source changes create a new version and close the release gate until the affected checks pass again.
Advertising boundary
Advertising cannot determine a formula, source, ranking, or review outcome. Ads remain off unless a page is released, indexable, individually approved for monetization, policy-safe, served on an allowed production host, and the visitor has provided any consent required for an ad request.
