How Qarn360 works
Canonical products and exact variants
Each device has one canonical identity and exact variants (storage, RAM, connectivity). We match offers to the exact variant, not just a name.
Ingestion, validation and matching
Data flows through controlled ingestion, then validation and normalization, then matching with human review for uncertain cases. Nothing publishes automatically.
Publication gates
An offer publishes only after fail-closed gates: explicit published state, correct market and currency, an approved source, and authorized data access.
Total cost and price observations
We compute item price, shipping and fees separately and never treat unknown as zero. Every price observation is an immutable record.
Anomaly exclusion and deal confidence
We detect anomalies and exclude them from public intelligence until reviewed. We then compute evidence confidence (deal-confidence-v1) with hard gates, showing "insufficient data" instead of a misleading number.
Recommendation and affiliate links
A "buy now" recommendation requires explicit thresholds. Retailer links are always direct — no opaque redirect — and monetization is enabled only with an approved account and a validated link.
