AI Poop-Analysis App Database Offered for Sale

404 Media reports that a Reddit post on r/DHExchange by user Ill_Car_7351 advertised "150k+ labeled and classified images of 💩 from roughly 25K different people," quoting the post verbatim. Per 404 Media, the dataset allegedly came from an app called PoopCheck, produced by a company referred to as Soft All Things. The article quotes the app that advertises, "Our AI analyzes your poop using the Bristol Stool Scale and advanced pattern recognition." 404 Media also reports the app displayed about 151,317 "shared stools" in its community and included a leaderboard feature.

Companies and researchers building image-based medical or health datasets should treat images of bodily outputs as high-risk, sensitive data. Industry-pattern observations: training ML models on such user-submitted images typically requires rigorous deidentification, informed consent, and IRB review when used for medical research, even if individual faces or names are not present.

The 404 Media piece frames this episode as part of a broader underground market for app-collected user data. Industry-pattern observations: marketplace demand for niche, hard-to-obtain labeled datasets can create incentives for secondary sales of data originally gathered for consumer features.

For practitioners and data stewards, monitor legal and ethical boundaries around reusing consumer-submitted health-adjacent images, platform terms that enable community sharing, and whether any entities claim ownership or offer to commercialize such collections. 404 Media documents the offer and forum reactions but does not cite statements from PoopCheck or Soft All Things on the dataset sale.
