Explore regional diagnostic trends, heatmaps, and top DTCs. Privacy-first. Aggregated. Updated frequently.
The OBD Index aggregates anonymized diagnostic trouble code (DTC) signals from consenting users to estimate regional vehicle health (0–100). We never store VIN/PII. Counts are thresholded and rounded for privacy.
DTCs, app version, coarse region (ISO-3166-2). No VIN, no license plate, no precise coordinates.
K-anonymity thresholds and aggregation windows. Small-population regions are smoothed or suppressed.
