In May 2021, Google Play announced the new Data safety section, which is a developer-provided disclosure for an app's data collection, sharing, and security practices.
This page can help you complete the requirements for this data disclosure in regards to your usage of Firebase Android SDKs. On this page, you can find information on whether and how our SDKs handle end-user data, including examples of applicable configurations or invocations you can control as the app developer.
We aim to be as transparent as possible in supporting you; however, as the app developer, you are solely responsible for deciding how to respond to Google Play's Data safety section form regarding your app's end-user data collection, sharing, and security practices.
How to use the information on this page
This page lists the end-user data collected by only the latest version of each Firebase Android SDK.
Each SDK has its own section later on this page where we provide information about data collected automatically versus data collected depending on your usage. Automatic collection means that the SDK collects specific data without you invoking any specific method or class in your app. However, in many cases, the data collected by the SDK depends on your app's specific usage of the product, meaning your app's configuration and how you invoke the SDK.
To complete your data disclosure, you can use Android's guide about data types to help you determine which data type best describes the collected data. In your data disclosure, make sure to also account for how your specific app shares and uses the collected data.
Overview of data encryption, data sharing, and data deletion for Firebase Android SDKs
| Data encryption | For the collected end-user data listed on this page, Firebase encrypts the data in transit using HTTPS. |
| Data sharing | For the collected end-user data listed on this page, Firebase does not transfer this data to third-parties except:
|
| Data deletion | Firebase enables developers to delete end-user data in a manner consistent with the functionality of the Firebase services. |
Firebase user agent
The Firebase user agent is not a Firebase Android SDK, but rather a bundle of information that's collected by several Firebase Android SDKs and includes the following:
Device metadata: OS version, name, model, brand, and form factor
App that was used to install your app (for example, the Play Store) (see documentation)
Which Firebase SDKs are used in your app, including their versions
The Firebase user agent is used internally by Google to determine platform and version adoption in order to provide, maintain, and improve Firebase services. It is never linked to a user or device identifier.
If a Firebase Android SDK collects the Firebase user agent, it will be listed in the SDK's section below.

Depending on how you configure or invoke the Vertex AI in Firebase SDK and the product's features, your app may collect end-user data that needs to be included in your data disclosure. Make sure that you account for any developer-defined end-user data that's collected by your specific usage.
Other considerations
If you use Vertex AI in Firebase with Firebase Authentication, and if an end-user is signed-in, then every request from Vertex AI in Firebase automatically includes the applicable User ID from Firebase Authentication.
Additional information
Purpose for data collection
Vertex AI in Firebase generally uses the collected data listed in the sub-sections above to invoke the backend service in response to requests from your app. Also, review the sub-sections above for information about how specific data may be used. In your data disclosure, make sure to also account for how you specifically use the collected data, in addition to how you use any developer-defined end-user data collected by the SDK.
Transitively included Firebase libraries
The Firebase libraries listed in this section are transitively included in some of the other Firebase libraries. None of the following libraries have an accessible surface for developers, but they might collect end-user data (see each library below for details).
Firebase sessions
com.google.firebase:firebase-sessions
Data collected automatically
The Firebase sessions SDK collects the following data automatically.
| Data | By default, the Firebase sessions SDK... |
|---|---|
| App metadata | Collects metadata about the application, such as the package name, OS information, SDK version, and network connection type. |
| Device metadata | Collects metadata about the application, such as device manufacturer and model. |
| Application metrics | Collects usage data such as the time an app was foregrounded to start a new session. |
Data collected depending on your usage
The Firebase sessions SDK doesn't have optional features that the developer can configure or invoke to collect other end-user data.
Additional Information
Purpose for data collection
The Firebase sessions SDK uses the collected data listed in the sub-sections above to provide crash and performance metrics for the application. Also, review the sub-sections above for information about how specific data may be used. In your data disclosure, make sure to also account for how you specifically use the collected data, in addition to how you use any developer-defined end-user data collected by the SDK.
