Platform detail
Sub-scores and key findings for each platform audited.
19% of sampled listing images retained GPS coordinates — the highest rate in our index. EXIF data broadly retained across uploads. WebP served inconsistently.
12% GPS leak with substantial EXIF retention. App uploads appear to strip less aggressively than web uploads. No modern format served in tested sample.
GPS leak rate in the C band. Partial EXIF stripping observed — some metadata removed, some retained. WebP served on majority of tested images.
15% GPS leak with high EXIF retention. Metadata stripping appears minimal. Predominantly JPEG delivery with no modern format detected in sample.
Strong performance across all sub-scores. GPS leak rare and EXIF largely stripped. WebP delivery solid. Minor gaps prevent A grade.
Moderate GPS leak and partial EXIF retention. Luxury positioning makes privacy gaps more notable. WebP served on majority of listing images.
No GPS exposure detected. Near-complete EXIF stripping. WebP delivery on 92% of tested images. Best performer in the index — professional image pipeline evident.
Good GPS and EXIF hygiene. Authenticated product images (sneakers, streetwear) predominantly studio shots — low natural GPS exposure. WebP served widely.
Seller-uploaded images show inconsistent processing. GPS leak in expected range given craft/home-studio photography. EXIF partially retained. WebP broadly available.
9% GPS leak across diverse seller base. Legacy image hosting pipeline shows uneven EXIF handling. Modern format adoption lags behind newer platforms.
Strong privacy posture. GOAT's authenticated marketplace model relies heavily on standardised studio and seller-submitted product shots — GPS exposure is rare. EXIF largely stripped. WebP broadly served.
14% GPS leak — second-highest in the expanded index. Peer-to-peer mobile-first upload flow means most listing images are shot and uploaded directly from smartphones with location services enabled. EXIF broadly retained. JPEG-dominant delivery.
8% GPS leak across a geographically diverse seller base. MercadoLibre's image CDN strips EXIF on the majority of paths, but inconsistencies persist — particularly for listings uploaded via the mobile app. WebP adoption is growing but uneven.
Excellent privacy posture — GPS rarely exposed and EXIF largely stripped. 0% modern format adoption.
