Editorial standard
Editorial Policy
Our goal is to make calculator software decisions easier to verify, compare and revisit.
Evidence and attribution
Factual product claims are checked against current vendor documentation, the product interface when available and other directly relevant primary material. Editorial conclusions are labeled through clear verdict and best-for language.
Freshness
The date on a page changes only when its decision-relevant content is reviewed or updated. The sitemap uses the same real modification date. Product pricing and plan limits are rechecked before material ranking updates.
Corrections
Substantive corrections are recorded in the changelog. Readers and vendors can submit specific evidence through the contact page. We review the evidence, not the requester's preferred conclusion.
