Primary-source first
Every substantive tool or marketplace verdict is tied to an official source. We prefer binding terms, licensing agreements and seller or contributor policies. Official help pages can explain implementation, but promotional copy, forum posts and third-party summaries do not override a narrower primary-source rule.
How we handle uncertainty
When an answer depends on plan, revenue, model, disclosure, destination or intended use, the verdict is conditional until those facts are known. If official sources conflict and the difference cannot be resolved by scope or date, we explain the conflict rather than selecting the more permissive interpretation.
Dates and policy changes
A provider’s published update date and our own review date are recorded as different facts. We do not refresh a date without reopening the source. When a rule changes, the affected tool, platform and combination pages must be reviewed together so that a new conclusion is not mixed with an old explanation.
Corrections
Material errors are corrected in the page content and in every affected checker result. A correction should identify the current primary source, remove the superseded conclusion and preserve a clear reviewed date. Readers can report a suspected error through the contact page.
Editorial independence
Advertising, sponsorship or affiliate relationships do not change a policy verdict, source choice or page ranking. Paid placements must be labeled and kept separate from the checker’s editorial result.
Limited, useful coverage
The checker supports 72 generator × destination combinations, while only the 40 combinations with bespoke editorial pair analysis are indexable. Extended checker results remain noindex and outside the sitemap until they add a materially distinct rule, decision or workflow. We do not create near-duplicate model, country, plan or keyword pages merely to increase URL count. A new indexable page must add a materially different rule, decision or workflow.
