Editorial Policy
How to interpret the publication’s sources, examples and commercial disclosures.
Sources and scope
Primary documentation and platform terms are the preferred references for product-specific facts. Links are provided so readers can compare our explanations with the source. This site does not operate a live fee, price or availability feed.
Examples and dates
Examples are simplified teaching tools and omit factors unless expressly stated. A publication date identifies when a page was produced, not a continuous verification of every external fact. Product rules should be checked again before use.
Corrections and commercial interests
Send proposed corrections with the page URL and supporting source to our support email. Referral links are labelled. The existence of a disclosure does not eliminate a financial conflict, so readers should also consult independent material.
