Why Pregnancy Apps Sell Your Data (And How to Check)

How Pregnancy Apps Make Money From Your Data

The pregnancy app market is worth billions, and the vast majority of that value isn't coming from subscriptions. It's coming from your reproductive health data. Here's how the pipeline works.

Ad-supported revenue models. When a pregnancy app is free, the product is your attention — and the data that makes ad targeting precise. Your due date, trimester, symptoms, and shopping interests are packaged into advertising profiles that fetch premium rates. Pregnancy data is among the most valuable demographic signals in digital advertising.

Data broker ecosystems. Beyond direct advertising, many apps share data with brokers who aggregate and resell it. Your pregnancy status, expected due date, and health conditions flow into databases purchased by insurance companies, employers, retailers, and political campaigns. A 2024 Duke University study found data brokers openly selling lists of pregnant women sorted by trimester and income level.

Third-party SDK tracking. Even apps that claim not to “sell” data often embed analytics and advertising SDKs — Facebook Pixel, Google Analytics, AppsFlyer, Adjust — that transmit user behavior to third parties. These SDKs collect device identifiers, usage patterns, and sometimes health data, creating a tracking profile that persists across apps and websites.

FTC enforcement tells the story. In 2021, the FTC settled with Flo Health for sharing sensitive fertility and pregnancy data with Facebook and Google analytics despite promising users their data was private. In 2023, the FTC took action against BetterHelp and GoodRx for similar violations. By 2024, the agency had established a clear pattern: health apps routinely share intimate data in ways that contradict their privacy promises.

The data being collected goes far beyond what most users expect: menstrual cycles, sexual activity, pregnancy loss history, symptoms suggesting complications, location data near clinics, and emotional states logged in journals. This isn't metadata — it's your most intimate health information.

Why Reproductive Health Data Is Different After Dobbs

Privacy in pregnancy apps was concerning before June 2022. After the Supreme Court's Dobbs v. Jackson decision overturned Roe v. Wade, it became potentially dangerous.

In states with restrictive abortion laws, reproductive health data can now be used as evidence. Law enforcement agencies can subpoena data from app companies, request geolocation records near clinics, or obtain period-tracking data that suggests a pregnancy that didn't result in a birth. This isn't hypothetical — prosecutors in multiple states have already sought digital evidence in reproductive health cases.

The legal landscape varies dramatically by state. Some states — like California, Washington, and New York — have passed laws protecting reproductive health data. Others have no such protections. And critically, most pregnancy apps are not covered by HIPAA. HIPAA only applies to healthcare providers and their business associates. A consumer pregnancy app that you download from the App Store has no HIPAA obligation whatsoever.

This means the only things standing between your reproductive health data and a law enforcement request are the company's privacy policy and its willingness to fight a subpoena. Most companies comply. And if your data is on their servers, compliance is straightforward — they hand it over.

Pregnancy data is uniquely sensitive because it reveals not just your current health status, but your reproductive decisions, timeline, and outcomes. No other category of health data carries the same legal risk in post-Dobbs America.

How to Audit Your Pregnancy App's Privacy

You don't need a law degree to evaluate whether your pregnancy app respects your privacy. Here's a five-point checklist you can run in under ten minutes.

Check for ads. Open the app and look for banner ads, sponsored content, or “recommended products.” If the app shows advertising, your data is funding the ad targeting that makes those ads appear. An ad-supported pregnancy app is monetizing your health data — full stop.
Read the data sharing section of the privacy policy. Skip to the section about sharing data with third parties. Look for phrases like “trusted partners,” “service providers,” “analytics partners,” or “affiliates.” Count how many third parties are listed. If the list is long or vague, your data is flowing to companies you've never heard of.
Check App Privacy labels in the App Store. Go to the app's listing in the App Store and scroll to “App Privacy.” Look at “Data Linked to You” and “Data Used to Track You.” If you see categories like “Health & Fitness,” “Identifiers,” or “Usage Data” under tracking, the app is linking your health data to your identity for advertising purposes.
Look for analytics and advertising SDKs. The privacy policy often lists the analytics tools used. Facebook SDK, Google Analytics for Firebase, AppsFlyer, Amplitude, Mixpanel — these all transmit behavioral data to third-party servers. Some privacy policies mention these by name. You can also check tools like Exodus Privacy (for Android) that scan apps for embedded trackers.
Check where your data is stored. Look for language about data storage. “Our secure servers” means the company possesses your health records and can access, share, or be compelled to hand them over. “On your device” or “local storage” means the data stays with you. The difference is fundamental: server-stored data can be breached, subpoenaed, or sold. Device-stored data cannot.

If your current pregnancy app fails more than one of these checks, your reproductive health data is likely being shared in ways you didn't explicitly agree to.

What Privacy by Architecture Means

Most pregnancy apps treat privacy as a policy problem: write rules about what employees can and can't do with data, publish a privacy policy, and hope for the best. MamaHush treats privacy as an architecture problem.

Local-first storage. Your health records — symptoms, medications, appointments, journal entries, kick counts, emergency card data — are stored in an encrypted database on your device. Not on our servers. Not in the cloud. On your phone, under your control. If our servers were breached tomorrow, your health records wouldn't be exposed because they were never there.

No ad-tech. Period. MamaHush contains zero advertising SDKs, zero data broker integrations, and zero third-party analytics that profile users. We use privacy-respecting analytics that count page views without identifying individuals. No Facebook Pixel. No Google Analytics. No AppsFlyer.

Subscription model. Our business model is simple: you pay for a subscription, and we provide a service. We have zero financial incentive to collect, analyze, or sell your data because we don't make money from advertising. Our revenue comes from building a product good enough that people want to pay for it.

This is the “can't vs. won't” distinction. Other apps say “we won't sell your data.” We say “we can't sell your data” — because we don't have it. Policies can change. Companies get acquired. Promises get broken. But architecture is structural. If your health records never leave your device, no policy change, acquisition, or subpoena can expose them.

Questions to Ask Any Health App

Before trusting any app with your pregnancy journey — including MamaHush — demand clear answers to these questions:

Where is my health data stored? On your servers or on my device? If it's on your servers, who can access it?
How do you make money? If the answer isn't “subscriptions” or “one-time purchase,” your data is likely part of the business model.
What happens if you receive a subpoena for my data? Do you have the data to hand over? Will you fight it? Have you received law enforcement requests before?
Which third-party SDKs are in the app? List every analytics, advertising, and tracking SDK embedded in the app. What data do they collect?
Is my data used to train AI models? Are my conversations, symptoms, or health records used to train or improve AI systems?
What happens to my data if the company is acquired? Does the privacy policy survive a sale? Can the acquiring company change the terms?
What happens when I delete the app? Is my data actually deleted from your servers, or just deactivated?

Any app that can't or won't answer these questions clearly doesn't deserve access to your reproductive health data.

Frequently Asked Questions

Do pregnancy apps sell my data?

Many free pregnancy apps monetize user data through advertising networks, data brokers, or partnerships with health companies. The FTC has taken enforcement action against multiple health apps for sharing sensitive reproductive data without meaningful consent. If a pregnancy app is free and shows ads, your data is almost certainly being used to generate advertising revenue.

Is Flo safe for pregnancy tracking?

Flo settled with the FTC in 2021 over allegations it shared user health data with Facebook and Google analytics despite promising privacy. While Flo has since introduced an “Anonymous Mode,” its core business model remains ad-supported. Users should carefully review Flo's current privacy practices and consider whether an advertising-funded model provides adequate protection for reproductive health data, especially in post-Dobbs legal environments.

Can pregnancy app data be subpoenaed?

Yes. If a company stores your reproductive health data on their servers, that data can be subpoenaed by law enforcement. After Dobbs, this is a real concern in states with restrictive laws. Most pregnancy apps are not covered by HIPAA and have limited legal grounds to resist a subpoena. Data stored locally on your device is significantly harder to access through legal process.

What is the safest pregnancy app for privacy?

The safest pregnancy apps use local-first data storage (health records stay on your device), have no advertising or data broker partnerships, use a subscription business model, and are transparent about what data leaves your device. Look for “can't access your data” over “won't access your data” — architecture is more trustworthy than promises.

How do I know if my pregnancy app shares data?

Run a five-point check: (1) Does the app show ads? (2) Does the privacy policy mention sharing with “partners” or “affiliates”? (3) What do the App Store privacy labels say under “Data Used to Track You”? (4) Are third-party analytics SDKs like Facebook or Google embedded in the app? (5) Is your data stored on their servers or on your device? If more than one answer concerns you, your data is likely being shared.

What is local-first data storage?

Local-first data storage means your health records — symptoms, medications, appointments, journal entries — are stored in an encrypted database on your device, not on a company's servers. The company literally cannot access, sell, or lose your health data in a breach because they never possess it. It's the strongest form of data protection available: privacy enforced by architecture, not by policy.
