Provenance

Every aggregated data point carries:

  • sourceUrl — the original public page we extracted from
  • retrievedAt — the ISO timestamp of extraction
  • originalValue — the raw string as it appeared on the source
  • confirmedBy[] — additional public sources that corroborate the same fact

When sources conflict, we keep the conflict visible rather than smoothing it away.

Data Freshness

  • Store prices and availability are detected daily via sitemap diff and updated on change.
  • Social mentions are added on weekly cycles.
  • Review aggregates refresh monthly.
  • Each page's dateModified follows real data changes, not artificial timestamp bumps.

What We Do Not Do

  • We do not rank brands or claim any brand is recommended.
  • We do not accept payment to modify displayed facts.
  • We do not fabricate missing values. Missing fields stay empty or pending.
  • We do not copy long-form user-generated text verbatim. We paraphrase and cite the source URL.
