Health Connect is Android’s central platform for health and fitness data, letting apps share steps, heart rate, sleep, blood pressure, glucose and more through one on-device store with user-controlled permissions. For healthcare apps serving Android users, it is now the standard way to access wearable and device data. Teams moving from older Google Fit integrations must also plan their migration. This guide explains how Health Connect works, the permission and Play Store rules that shape integrations, and how to build reliably for healthcare. It supports our healthcare app development services. Planning an Android health app? Request a free mobile architecture review.
How Health Connect Works
Health Connect stores health and fitness data on the user’s Android device and lets approved apps read and write specific data types. Users manage permissions centrally, deciding exactly which apps can access which information, and can revoke access at any time.
An on-device data platform
Health Connect keeps data on the device rather than in a cloud service, combining information from wearables, fitness apps and health apps. Your app reads and writes through Android APIs, so you control what leaves the device and how it is protected afterward.
Built into modern Android
On recent Android versions, Health Connect is part of the operating system, while older supported versions use an installable app. Your integration should check availability and guide users through any setup steps, because availability varies across devices and Android versions in the field.
Records and data types
Health Connect organizes data into record types, such as steps, heart rate, sleep sessions, blood pressure, blood glucose and weight. Each record includes timing, values and metadata about the source. Request only the record types your features genuinely require. Review choices every release.
Reading, writing and changes
Apps can read records written by other apps and write their own, such as readings from connected devices. Health Connect also supports retrieving changes since a previous sync, which helps apps update efficiently instead of rereading large amounts of historical data repeatedly.
Permissions and Play Store Rules
Health Connect permissions are granular and closely tied to Google Play policies. Planning permissions and policy declarations early prevents rejected releases and confusing user experiences, especially for healthcare apps requesting many sensitive data types.
Granular read and write permissions
Each data type has separate read and write permissions, and users grant them individually. Request permissions in context, explaining why each type matters. Clear explanations improve grant rates and help users feel confident sharing sensitive health information with your app.
Historical and background access
By default, apps can read limited recent history, with additional permissions available for older data and background reads. Request these only when needed, and explain why. Monitoring apps often need background access, so design flows that justify it clearly to users.
Google Play declarations
Apps requesting Health Connect permissions must complete Google Play declarations describing how they use health data, and must follow Play’s health data policies. Prepare accurate declarations and privacy policies early, because incomplete submissions delay app review and release timelines. Keep declarations updated.
Privacy and data use limits
Google restricts how Health Connect data can be used, including limits on advertising and data sales. Use data only for features users understand. Review current Play policies regularly, because policy updates can affect existing apps as well as new submissions.
Migrating From Google Fit
Many existing Android health apps were built on Google Fit APIs. Google has deprecated those APIs in favor of Health Connect, so teams maintaining older integrations need a migration plan that protects users and avoids data gaps.
Why migration matters
Apps relying on deprecated Google Fit APIs risk losing data access as those services wind down. Migrating to Health Connect keeps integrations supported and aligned with modern Android privacy expectations. Confirm current deprecation timelines in Google’s developer documentation. Plan migration work early.
Mapping data types
Map each Google Fit data type you use to its Health Connect equivalent, noting differences in structure, units and metadata. Some types may not map perfectly. Document mappings and test them carefully, so trends and alerts remain accurate after migration.
Handling historical data
Decide how to handle historical data previously collected through Google Fit, including what remains on your servers and what users must re-authorize. Communicate changes clearly to users, so they understand new permission requests and why reconnecting is necessary. Test the reconnection experience carefully.
Running both during transition
Some teams temporarily support both integrations while users update apps and grant new permissions. Plan this period carefully to avoid duplicate readings. Remove legacy code promptly once migration completes, reducing maintenance burden and security exposure. Set a clear end date for supporting the legacy integration.
Health Connect and HIPAA
Health Connect is an on-device consumer platform, and Google is not acting as your business associate for data stored there. HIPAA obligations depend on whether your app serves a covered entity and how you handle data after it leaves the device.
When data becomes PHI
If your app is provided by or for a health system, clinic or other covered entity, health data you transmit to clinical systems is usually PHI. Consumer apps chosen independently by users may fall outside HIPAA but still face privacy laws.
Securing transmitted data
Once data leaves the device, protect it with encryption, strong authentication, audit logging and HIPAA-eligible hosting where required. Our HIPAA-compliant app development practice builds these safeguards into mobile health platforms. Every safeguard is documented for security reviews, helping your team answer questions from health system partners quickly.
Consent for clinical sharing
When clinicians review readings, users should clearly understand who sees their data and how to stop sharing. Explicit consent screens and easy controls build trust and support compliance with privacy laws and platform policies alike. Revisit consent wording as features change.
Minimizing collected data
Collect only data needed for your features, at the frequency required. Smaller datasets reduce security risk, storage costs and compliance effort, and make Play Store declarations easier to justify during app review. Review requested types regularly as features evolve. Less is safer.
Building a Health Connect Integration
The steps below reflect how we deliver Health Connect integrations for healthcare apps. They prioritize data purpose, permissions and reliable sync, because these factors drive Play Store approval, user trust and the quality of data reaching care teams.
Step 1: Define data and purpose
List each record type your app needs, why and how often. Map types to features and clinical goals. This list guides permission requests, Play Store declarations and backend data design, keeping the integration focused and defensible. Review the list with stakeholders.
Step 2: Design permission flows
Design in-context permission requests with clear explanations, and plan for denied or partial permissions. Include guidance for users who need to change settings later. Thoughtful flows improve grant rates and reduce support requests after launch. Test flows with real users first.
Step 3: Implement reads, writes and sync
Implement reading, writing and change-based sync, handling duplicates, units and time zones carefully. Use background reads only where justified. Reliable sync prevents missing or duplicated readings that could mislead clinicians monitoring patient health. Log sync errors for faster troubleshooting. Test edge cases.
Step 4: Connect to clinical systems
Send data securely to your backend and integrate it with dashboards, EHRs or analytics using standards such as FHIR. Our remote patient monitoring software development team connects device data to care workflows. Every pipeline includes monitoring and clear documentation. Test end to end.
Step 5: Test, submit and monitor
Test across Android versions and devices, including those requiring the installable Health Connect app. Complete Play declarations accurately before submission. After launch, monitor sync errors, permission rates and user feedback to improve reliability continuously. Fix issues quickly between releases. Track trends.
