Privacy-Focused Pregnancy and Health Apps

Pregnancy apps collect some of the most sensitive data imaginable — gestational age, symptoms, medical history, location, and intimate physical details. This data is routinely sold to data brokers, insurers, employers, and marketers. Several major apps have shared user data with law enforcement following abortion-related investigations.

This guide covers what to look for, which apps are worth trusting, and how to minimize exposure if you must use a mainstream option.

Why Pregnancy Data Is High-Risk

Pregnancy and reproductive health data sits in a unique legal gray zone. In the United States post-Dobbs, this data has been subpoenaed by state prosecutors. Even in jurisdictions where abortion is legal, the data trails created by these apps can be:

Sold to health insurance underwriters who adjust pricing
Shared with employers via wellness programs
Aggregated by data brokers and sold to anyone willing to pay
Used in targeted advertising for formula, diapers, or debt products
Accessed via law enforcement legal process without a warrant in many states

Threat Model Questions

Before picking any app, answer these:

Do you need cloud backup/sync, or is local-only acceptable?
Are you in a jurisdiction where reproductive data could be weaponized legally?
Do you want to share data with a partner or healthcare provider?
Are you using iOS or Android?

Your answers determine how strict your requirements need to be.

The Privacy Audit Checklist

For any health app, verify these before entering data:

[ ] Privacy policy reviewed — does it explicitly prohibit selling data?
[ ] Can you use the app without creating an account?
[ ] Does the app work without internet access?
[ ] Is there an export/delete function for all your data?
[ ] Does the policy explicitly address law enforcement requests?
[ ] Is the app open source or independently audited?
[ ] Does it use end-to-end encryption if syncing?

Recommended Apps

Drip (Android/iOS — Open Source)

Drip is an open-source menstrual and reproductive health tracker that stores all data locally on the device with no account required. The source code is publicly available on GitHub, meaning independent researchers can verify what it does and doesn’t transmit.

Key facts:

All data stays on your device by default
No account creation required
No third-party analytics SDKs
Supports export to CSV for backup
Available on F-Droid (Android) for accountless install

Privacy verdict: Excellent. Drip is the go-to recommendation for anyone in a high-risk legal jurisdiction.

Euki (Android/iOS)

Euki is built by a reproductive health advocacy organization explicitly focused on user privacy in the post-Dobbs landscape. It includes a PIN lock and a “quick exit” button that closes the app and wipes recent session data.

Key facts:

No data collected or transmitted to servers
PIN protection built in
Quick exit feature for safety
Includes pregnancy information and symptom tracking
Free, no ads

Privacy verdict: Excellent. Designed specifically for people concerned about legal exposure.

What to Avoid

Apps to stay away from if privacy is a concern:

Glow, Flo, BabyCenter — All have histories of sharing data with third parties. Flo signed a FTC consent order in 2021 after sharing health data with Facebook and Google despite promises not to. They’ve improved somewhat, but their business model depends on data monetization.

The Bump, What to Expect — These are content/community platforms owned by large media companies. Extensive ad tracking, data sharing with partners.

Any app tied to your insurance or employer wellness program — These apps often have contractual data sharing obligations that override any privacy policy.

Hardening a Mainstream App If You Must Use One

If your OB or midwife requires a specific app that isn’t privacy-friendly, apply these mitigations:

# Android: Use a work profile to isolate the app
# Install Shelter from F-Droid to create a work profile

# Revoke unnecessary permissions via adb
adb shell pm revoke com.example.pregnancyapp android.permission.ACCESS_FINE_LOCATION
adb shell pm revoke com.example.pregnancyapp android.permission.READ_CONTACTS

# Block the app's network access using NetGuard (no-root firewall)
# Install NetGuard from F-Droid, add the app to the blocklist

On iOS:

Settings > Privacy & Security > Tracking — deny tracking permission
Settings > [App Name] — revoke Location, Contacts, Photos access
Settings > Privacy & Security > Health — review exactly what the app can read

Data Minimization Principles

Regardless of which app you use:

Never enter your real name or date of birth in an app that doesn’t require identity verification
Use a separate email address — create a dedicated alias via SimpleLogin or AnonAddy
Disable cloud backup for any folder where the app stores its data (check Android’s auto-backup settings and iCloud settings)
Export and locally encrypt your data periodically, then delete it from the app’s history
Uninstall the app after you no longer need it and explicitly request data deletion

Requesting Data Deletion

Most apps in the US and EU must honor data deletion requests under CCPA and GDPR. Template message:

Subject: Data Deletion Request — [Your Username or Email]

I am requesting immediate deletion of all personal data associated
with my account under [CCPA / GDPR Article 17].

This includes: all profile data, tracked health events, location
data, usage logs, and any derived inferences. Please confirm
deletion within the required timeframe.

Send this via email to the privacy contact listed in the app’s privacy policy. Screenshot or save the response.
