Data sources and verification

What is checked, what is not, and how to get something corrected. We publish this because a directory is only worth reading if you can tell verified facts from placeholders.

Three states of information

StateWhat it meansWhere you see it
VerifiedChecked against a manufacturer, standards body or store listing. The source link is shown on the record.Brand official sites, app store links, protocol and standards pages
EditorialOur own summary or scoring. Clearly opinion, with the method stated. Not a measurement.Comparison scores, brand coverage index, AI signal estimates
PlaceholderSample data for layout review. Not real. Must not be relied on.Amazon ASINs, rankings, prices, ratings; some app store links are search links rather than direct listings

What we do not do

  • We do not invent a company relationship. An app is attributed to a parent company only when the app is that vendor's own first-party app or the relationship is documented.
  • We do not present an estimate as a measurement. AI signals and scores are labelled as estimates with stated inputs.
  • We do not publish a product record without a source link. Records that cannot be sourced are removed rather than padded out.
  • We do not rank companies by financial value. The brand coverage index describes what a catalogue covers, not what a company is worth.

Corrections

If a record is wrong - a misattributed brand, a dead link, an incorrect specification, a product that no longer exists - send it to us with the source that shows the correct value.

Brands and manufacturers: you may request a correction, a clarification or the removal of a record. We will respond and, where the request is supported, update the record and note the change.

Known gaps at this stage

  • Marketplace data (ASIN, rank, price, rating) is preview data until a licensed source is connected.
  • Some app store links point at an official store search rather than a direct package listing.
  • Comparison scores and the brand coverage index are editorial estimates, not benchmarks.
  • Legal pages are drafts pending jurisdiction-specific review.
