Can AI Health Apps Sell Your Data to Third Parties?

Many AI health apps legally can sell or share user data with third parties, especially when they aren't covered by HIPAA, so whether a specific app does this depends on its privacy policy and applicable state or national privacy laws rather than any blanket protection for health data.

Key takeaways

Apps not covered by HIPAA are generally governed instead by their own privacy policy and by broader consumer privacy laws, which vary by jurisdiction.
Some jurisdictions have specific laws restricting the sale of health or biometric data, but coverage is inconsistent across regions.
Reading an app's actual privacy policy is the most reliable way to know its specific data-sharing practices.
Terms like 'we don't sell your data' can still allow broad data 'sharing' with partners, so exact wording matters.

Yes, in Many Cases This Is Legally Possible

It can come as a surprise, but many AI-powered health and wellness apps are legally permitted to sell or share user data with third parties. This is largely because a large share of these apps are not “covered entities” under HIPAA, meaning the specific federal restrictions that apply to hospitals, doctors, and insurers simply don’t govern them. Instead, these apps are generally bound by whatever their own privacy policy says, along with any applicable state, national, or regional consumer privacy laws — and those obligations can be far looser than most users assume when they see the word “health” attached to an app.

This gap between user expectations and actual legal protection is one of the most significant and under-recognized issues in digital health data privacy today.

Why the Language in Privacy Policies Matters So Much

Companies sometimes state prominently that they “don’t sell” user data, which can create a reassuring impression while still permitting extensive data “sharing” with advertising partners, analytics providers, or affiliated companies — practices that may functionally resemble a sale in terms of outcome, even if it isn’t structured as a traditional cash transaction for data. Because there isn’t one uniform legal definition of “sale” that applies everywhere, the specific wording an app uses in its privacy policy is often the only reliable way to understand what actually happens to a given piece of user data, rather than relying on general marketing language.

This is why reading the actual data-sharing and third-party sections of a privacy policy, rather than trusting a headline claim, is the most reliable way for a user to understand a specific app’s practices.

The Regulatory Landscape Is Uneven

Some jurisdictions have moved to create specific protections for health and biometric data outside of HIPAA, recognizing that consumer health apps represent a meaningful privacy gap. However, these protections are not uniform, and their existence, scope, and enforcement vary considerably depending on where both the company and the user are located. This patchwork means the same app could be subject to very different obligations depending on the jurisdiction, and a global user base doesn’t guarantee consistent data protection for every user.

Bottom Line

Yes, many AI health apps can legally sell or share user data with third parties, particularly when they fall outside HIPAA’s scope, so understanding a specific app’s actual privacy policy — not just assumptions based on the word “health” — is the most reliable way to know what happens to your data.

Important caveats

Privacy policies and applicable laws change over time and vary by company and region, so this is general guidance rather than a review of any specific app.

Frequently asked questions

How can I find out if a specific health app sells my data?

The most direct way is to read the app's privacy policy, specifically the sections describing data sharing, third-party partners, and any opt-out options. Some apps also provide account settings to limit certain kinds of data sharing.

Are there laws specifically protecting health app data from being sold?

Some jurisdictions have enacted specific health or biometric data privacy laws with restrictions on sale or sharing, but there isn't one uniform standard, and protections vary significantly depending on where a user and company are located.

Does deleting the app stop the sharing of data already collected?

Not necessarily — deleting an app typically doesn't automatically delete or recall data already shared with third parties in the past. Checking the app's data deletion and retention policy is the best way to understand what happens to previously collected data.
