Our accuracy commitment

Five promises — each shown beside the live, computed proof that backs it. Because every proof is derived from the same data it describes, we cannot quietly break a promise without visibly breaking this page. Trust you can check, not just read.

1. History is never rewritten.

   ✓ The append-only hash-chain verifies clean — unbroken, 15 entries, head 556c9126709b…. Verify →

2. Every figure is sourced and dated.

   ✓ 3,954 products and tools tracked across 501 categories, each price linked to the seller's page and dated; tracking since June 2026. Verify →

3. A null beats a guess.

   ✓ Where a price or spec cannot be sourced, we publish nothing rather than a guess. Quote-only vendors return null, never a fabricated number. Verify →

4. Corrections are free for everyone, and logged.

   ✓ Every correction is public, dated, and emitted as a machine-readable ClaimReview. Accuracy is never paywalled. Verify →

5. No ranking is ever for sale.

   ✓ Ordering is a published, versioned algorithm computed from the data itself; paid verification is a machine-readable flag that never changes a position, score or inclusion. Verify →
