Building a mobile health app brings HIPAA into your technology stack. The Health Insurance Portability and Accountability Act requires that covered entities and their business associates protect "Protected Health Information" (PHI). When crash reports and session data from your health app flow to a third-party monitoring tool, that tool becomes a business associate — and must sign a Business Associate Agreement (BAA) before you send it any PHI.

This guide covers what qualifies as PHI in a mobile app context, which monitoring tools offer BAAs, and how to configure crash reporting to stay HIPAA-compliant.

What Qualifies as PHI in a Mobile App

PHI is individually identifiable health information. In a mobile health app, PHI could be present in:

Session content: If a user views their diagnosis, lab results, or medication list and you're capturing screen video, that's PHI in your crash data
Network request bodies: A POST to /api/appointments with a body containing a diagnosis code or patient ID is PHI
Custom breadcrumbs: If you log "User viewed diabetes management screen" with a user identifier, that combination may be PHI
Error messages: Exceptions thrown by medical data parsing may contain PHI in the error message string

Importantly, anonymized data is not PHI. If you remove all 18 HIPAA identifiers (name, date of birth, geographic data smaller than state, phone, email, SSN, device identifiers, etc.), the remaining data is de-identified and not subject to HIPAA.

The Business Associate Agreement Requirement

Any vendor who "creates, receives, maintains, or transmits" PHI on your behalf is a business associate under HIPAA and must sign a BAA before you send them any PHI.

This applies to your crash reporter if:

Session replay captures screen content showing PHI
Network monitoring captures request/response bodies containing PHI
You log custom events that include PHI

Common mobile monitoring tools and their BAA availability:

Firebase Crashlytics: Google offers BAAs for Google Workspace enterprise, but standard Firebase does not come with a BAA. Not suitable for PHI without explicit Google HIPAA agreement.
Sentry: Offers BAA for qualifying Sentry Business/Enterprise customers. Video session replay needs to be disabled or masked.
BugsPulse: Available to enterprise customers on request. Event-based replay means screen PHI is never captured. Safe to use with appropriate configuration.

Configuration for HIPAA-Safe Crash Reporting

The safest approach minimizes PHI reaching your crash reporter at all:

BugsPulse.init({
  apiKey: process.env.BUGSPULSE_KEY,

  // NEVER capture request/response bodies in a health app
  captureNetworkRequestBodies: false,
  captureNetworkResponseBodies: false,

  // Sanitize URLs that may contain patient identifiers
  networkUrlSanitizer: (url) => {
    return url
      .replace(//patients/[^/]+/, '/patients/[REDACTED]')
      .replace(//users/d+/, '/users/[REDACTED]');
  },

  // Don't use video session replay
  sessionReplay: true,         // event-based only — no screen capture
  captureScreenshots: false,   // explicitly disable if option exists

  // Don't set user identity to PHI
  // setUser({ id: user.medicalRecordNumber }) // WRONG
  // setUser({ id: user.internalDbId })        // OK — opaque internal ID
});

Custom breadcrumbs: be careful with health context

// WRONG — health information in breadcrumb
BugsPulse.addBreadcrumb({
  message: `User viewed diabetes treatment plan`, // PHI
});

// CORRECT — de-identified navigation context
BugsPulse.addBreadcrumb({
  message: 'User viewed care plan screen',  // no diagnosis
  data: { screen: 'CarePlanScreen' },
});

Network Monitoring in Health Apps

Network monitoring is valuable for debugging but high-risk for PHI. The safe configuration:

// Capture network metadata (URL, status, timing) WITHOUT bodies
BugsPulse.init({
  captureNetworkRequests: true,  // captures URL + status + timing
  captureNetworkRequestBodies: false,   // NO request bodies
  captureNetworkResponseBodies: false,  // NO response bodies
  captureNetworkHeaders: false,         // NO headers (may contain auth tokens with PHI)
});

This gives you: "POST /api/appointments returned 500, took 1.2s" — enough to debug the crash without capturing any appointment data.

De-identification Strategy

If you want richer crash context, de-identify data before it leaves the device:

// Flutter example — de-identify before logging
void logUserContext(Patient patient) {
  BugsPulse.setUser(
    id: patient.internalId,  // opaque UUID, not MRN or SSN
    // Do NOT set: name, DOB, diagnosis, insurance ID
  );
}

The Non-PHI Approach: What You Can Safely Capture

You can capture substantial debugging context without touching PHI:

App version, device model, OS version
Navigation path (screen names, not health content)
Network request metadata (URL, method, status code, duration) — no bodies
Crash stack traces — as long as error messages don't contain PHI
Custom events describing app state (e.g., "user completed onboarding") — not health data

This is usually sufficient to debug 95% of production crashes without any HIPAA exposure.

Summary

HIPAA compliance for mobile health app monitoring requires: a BAA with your monitoring vendor if PHI may be transmitted, configuration to prevent request/response body capture, no screen video recording, and careful de-identification of any custom events that might reference health context. Event-based crash reporting and session replay — which capture behavior, not content — is the architecturally safest approach for health apps.
