TL;DR
A developer of the PoopCheck app is offering a database of over 150,000 user-submitted stool images for sale. The app claims to prioritize privacy, but the data agreement reveals it is used for AI training and commercial purposes. This incident highlights potential privacy violations and data misuse risks in health-related apps.
A developer of the PoopCheck app has publicly offered a database of over 150,000 user-submitted stool images for sale, raising concerns about privacy violations and data misuse in health apps.
The database was collected from approximately 25,000 users over several years through the PoopCheck app, which analyzes stool images to provide digestive health insights. The developer, identified as Ill_Car_7351 on Reddit, posted the database for sale, claiming it contains rare, labeled images that could be valuable for machine learning and medical research.
The PoopCheck app, created by Soft All Things, advertises itself as prioritizing user privacy, stating on its App Store page that it does not collect data and encrypts user information. However, the app’s Terms and Conditions explicitly state that by uploading images, users grant the company a license to use, reproduce, and sell the data for AI training and commercial purposes. The agreement also allows for the sharing or sale of data to third parties, including research institutions and medical organizations.
Why It Matters
This incident exposes significant privacy concerns regarding health-related apps that collect sensitive data under the guise of privacy. The revelation that user images are being used for AI training and sold to third parties raises questions about informed consent and the adequacy of privacy policies. For users, this highlights the potential risks of data misuse and the importance of scrutinizing app terms before sharing personal health information.

Background
In recent years, health and wellness apps have increasingly integrated AI features, often collecting personal health data. While many apps claim to prioritize privacy, legal documents and user agreements sometimes grant broad rights for data use, including commercialization and sharing. The PoopCheck app, launched by Soft All Things, has been available for several years, with a community of users sharing sensitive stool images. The recent disclosure of the data sale indicates a disconnect between privacy claims and actual data practices, a pattern seen in other health tech products.
“I’ve got 150k+ labeled and classified images of 💩 from roughly 25K different people. I know there’s a lot of value in it (hard to obtain, useful for ML, cancer studies etc) but not sure on how to move about it.”

Key Questions
Is my data safe if I use health apps like PoopCheck?
It depends on the app’s privacy policies and how they handle user data. Many health apps include clauses that allow data sharing or sale, which may not be transparent to users.
Can I delete my data from the PoopCheck app?
The app states that account deletion removes personal profile data, but anonymized or aggregated data may remain in AI models or datasets already used or sold.
What legal protections exist against data misuse in health apps?
Legal protections vary by jurisdiction. Regulations like GDPR and HIPAA aim to protect health data, but enforcement depends on the app’s compliance and transparency.
