Automatically collected user properties
As long as you use the Firebase SDK, you don't need to write any additional code to collect a number of user properties automatically. All of these user properties are available for use in Audience conditions, and some of them are also available as general report filters. Note that for iOS apps, the app must collect IDFA (i.e., add the AdSupport framework to the project) in order to automatically collect the Age, Gender, and Interests user properties.
|Age||Text||Identifies users by six categories: 18-24, 25-34, 35-44, 45-54, 55-64, and 65+.|
|App Store||Text||The store from which the app was downloaded and installed.|
|App Version||Text||The versionName (Android) or the Bundle version (iOS).|
|Country||Text||The country the user resides in.|
|Device Brand||Text||The brand name of the mobile device (e.g. Motorola, LG or Samsung).|
|Device Category||Text||The category of the mobile device (e.g. mobile or tablet).|
|Device Model||Text||The mobile device model name (e.g. iPhone 5s or SM-J500M).|
|First Open Time||Number||The time (in milliseconds, UTC) at which the user first opened the app, rounded up to the next hour.|
|Gender||Text||Identifies users as either male or female.|
|Interests||Text||Lists the interests of the user, e.g. "Arts & Entertainment, Games, Sports".|
|Language||Text||The language setting of the device OS (e.g. en-us or pt-br).|
|New/Established||N/A||New: First opened the app within the last 7 days.
Established: First opened the app more than 7 days ago.
|OS Version||Text||The version of the device OS (e.g. 9.3.2 or 5.1.1).|
Where Analytics gets demographics and interests data
Analytics collects demographics and interests data from the following sources:
- The Android Advertising ID. Applies to app activity only. Analytics generates an identifier based on the ID that includes demographic and interest information associated with users’ app activity.
The iOS Identifier for Advertisers (IDFA). Applies to app activity only. Analytics generates an identifier based on the IDFA that includes demographic and interest information associated with users’ app activity.
When the Device Advertising ID is not present, Analytics cannot collect demographics and interests information. Consequently, demographics and interests data may only be available for a subset of your users, and may not represent the overall composition of your traffic.
Thresholds are applied to prevent anyone viewing a report from inferring the demographics or interests of individual users. When a report contains Age, Gender, or Interests, a threshold may be applied and some data may be withheld from the report. For example, if there are fewer than N instances of Gender=male in a report, then data for the male value may be withheld.
If a threshold has been applied to a report, you will see a notice.
