## What is Google's role in this project?

Google led the design and development of the open source components and design
guidelines published as part of the Open Health Stack (OHS).

**Note:** As of December '25, ownership of the project has been transferred to
the Linux Foundation and we are in the process of establishing the Open Health
Stack Software Foundation with partners in the ecosystem.

## What is FHIR?

FHIR (Fast Healthcare Interoperability Resources) is the latest version of the
HL7 standard for building modern patient centered healthcare applications - see
[getting started with
FHIR](https://developers.google.com/open-health-stack/resources/getting-started-with-fhir).

## Why is Open Health Stack needed?

Open standards, such as [FHIR](https://www.hl7.org/fhir/index.html),
are gaining a lot of attention and have continued to show momentum with
increased awareness and interest. For developers it can be challenging to adopt
new standards into solutions, especially for those building for
resource-constrained settings. Open Health Stack makes it easier for developers
to leverage the FHIR standard, easing its adoption into digital health
solutions. OHS components provide a rich set of features relevant to developers
that simplify transitioning to FHIR. For example, the Android FHIR SDK provides
bi-directional sync and storage to enable full offline capabilities for mobile
app developers.

## What kinds of use cases does Open Health Stack support?

OHS has been designed to address the needs of developers building digital health
solutions for health workers who often operate in areas with poor connectivity.
Solutions built using OHS components can support any kind of healthcare program
and through our collaboration with the World Health Organization, OHS based
solutions are able to run the WHO Smart Guidelines content that makes evidence
based care easy to deploy. See our [use cases](https://developers.google.com/open-health-stack/use-cases) and
[stories](https://developers.google.com/open-health-stack/stories) to see how developers are using OHS
today.

## Who is Google working with?

We're collaborating with the World Health Organization and a community of
developers on Open Health Stack. To date developers from Ona, IPRD Solutions,
IntelliSOFT Consulting, Argusoft, and a number of independent software
engineers have contributed to the codebase.

**Note:** As of December '25, ownership of the project has been transferred to
the Linux Foundation and we are in the process of establishing the Open Health
Stack Software Foundation with partners in the ecosystem.

## Is Open Health Stack a managed service?

No. Open Health Stack provides a suite of building blocks that developers use to
build and implement their own solutions. These can be deployed in local
data-centers or on cloud providers.

## What does Google do with the data?

Google does not receive, collect, store or process any data.
