Pregnancy Apps That Don't Share Data: How to Check

Store facts checked 20 October 2026 · Written by the Momi team · Medically reviewed by: Safi Allah Khan (not required for this privacy guide, but included for consistency)
Quick answer: Few pregnancy apps share no data at all, so look for pregnancy apps that don't share data with advertisers. Open the App Store "App Privacy" section or Google Play "Data safety" before downloading and check for "Data Used to Track You". Momi's free version does show ads and has that label; we explain exactly what it lists below.
Disclosure: Momi is our app. This page tells you what its own label says, plainly, so you can decide.
How to read App Store privacy labels
Every App Store listing has an App Privacy section, filled in by the developer. Apple notes this information isn't verified by Apple. It has three parts:
| Section | What it means |
|---|---|
| Data Used to Track You | Data that "may be used to track you across apps and websites owned by other companies", usually for advertising |
| Data Linked to You | Data collected and tied to your identity (account, device or user ID) |
| Data Not Linked to You | Data collected without being tied to your identity |
Each section shows what data (such as health, contact info, identifiers, usage data) and why (such as app functionality, analytics, third-party advertising).
An app that shows "Data Not Collected" says it collects nothing. That's rare for pregnancy apps with accounts or ads.
How to read Google Play Data safety
Google Play's Data safety section shows:
- whether data is shared with third parties
- what data is collected and why
- whether data is encrypted in transit
- whether you can request deletion
Google says the information comes from the developer. Look also for the "Contains ads" label near the install button.
Momi's privacy label, honestly
Here's what Momi's US App Store App Privacy section listed on 20 October 2026:
| Section | Data types | Purposes listed |
|---|---|---|
| Data Used to Track You | Contact info, identifiers | Tracking across other companies' apps and websites |
| Data Linked to You | Identifiers (user ID), health, email address, name | Third-party advertising, analytics, app functionality |
| Data Not Linked to You | Device ID, usage data, advertising data, crash and performance data | Third-party advertising, developer's advertising, analytics, diagnostics, app functionality |
What this means: the free version of Momi is supported by ads, and identifiers and some contact info may be used for advertising across other companies' apps. Health data is listed as linked to you for app functionality. If that isn't right for you, consider turning off tracking (below), choosing Premium to remove ads, or choosing another app.
Momi's privacy policy names Google Play Services, AdMob and Google Analytics for Firebase as third-party services. See our privacy policy for details and how to ask for your data to be deleted.
How other pregnancy apps compare
In our check of the US App Store on 20 October 2026 (see best pregnancy apps), What to Expect, BabyCenter, The Bump, Pregnancy+, Flo and Momi all had a "Data Used to Track You" section. Ovia was the only one whose label didn't, though it still listed data linked to you. Consumer Reports' 2026 evaluation of four pregnancy apps also looked at privacy and security and rated What to Expect's privacy only fair.
Labels change when apps update, so check the current listing before you download.
A cautionary example
In June 2021, the US Federal Trade Commission finalized an order against Flo Health after alleging the app had shared sensitive health data, including pregnancy information, with analytics providers such as Facebook and Google. The order requires Flo to get users' consent before sharing health data. It's a reminder to read labels and policies carefully. For a fuller look, see Momi vs Flo.
Tips to limit sharing
- Turn off app tracking on iPhone. Apple Support explains: Settings, Privacy & Security, Tracking, then turn off "Allow Apps to Request to Track" or turn it off app by app.
- Share only what you need. Most week-by-week features only need your due date.
- Skip optional fields such as your name, birthday or location if the app works without them.
- Use a separate email for app sign-ups if you want.
- Check permissions for location, contacts and photos, and allow only what a feature needs.
- Read the privacy policy, especially the sections on third parties, sale of data and deletion.
- Delete data when you're done. Ask the developer to delete your data, then delete the app.
Is HIPAA protecting my app data?
Usually not. In the US, HIPAA applies to healthcare providers, health plans and their business associates. HHS guidance explains that a consumer app isn't covered just because you enter health information into it. Most pregnancy apps you download yourself aren't covered, so your data is protected mainly by the app's own policy and consumer protection law. Notes in a hospital's patient portal are different.
How Momi helps
Momi keeps the basics simple: you can track your pregnancy from your due date, keep a diary and bump photos, and use the kick counter and contraction timer. Our free web tools, such as the due date calculator, work in your browser without an account.
Download Momi free on the App Store or Google Play. Free with ads; optional Premium.

FAQ
Are there pregnancy apps that don't share data?
Very few apps share nothing at all. Most collect some data for the app to work, and many free apps share data with advertising partners. When we checked the US App Store in October 2026, Ovia's label had no 'Data Used to Track You' section, but it still listed data linked to you. Always check the label yourself.
Does Momi share my data?
Momi's free version shows ads, and its App Store label includes 'Data Used to Track You' for contact info and identifiers. It also lists data linked to you for advertising, analytics and app functionality, including health data. Read the label and Momi's privacy policy before you sign up.
Do pregnancy apps sell your data?
It depends on the app. Selling data and sharing it for advertising are different, and each app's privacy policy explains what it does. In 2021 the FTC finalized an order requiring Flo Health to get users' consent before sharing health data, after alleging it had shared sensitive data with analytics providers.
How do I stop a pregnancy app from tracking me?
On iPhone, go to Settings, Privacy & Security, Tracking, and turn off Allow Apps to Request to Track, or turn it off for a specific app. On Android, review the app's Data safety section and your ad settings. Share only the information you need.
Is HIPAA protecting my pregnancy app data?
Usually not. In the US, HIPAA covers healthcare providers, health plans and their partners, not most consumer apps you download yourself. App data is governed mainly by the app's privacy policy and consumer protection laws, so read the policy carefully.
