Google Analytics offers features which allow you to control the collection and use of Analytics data.
Disable Analytics data collection
In some cases, you may wish to temporarily or permanently disable collection of Analytics data, such as to collect end-user consent or to fulfill legal obligations. Google Analytics offers multiple options for disabling and deactivating Analytics collection. Used together, they support many typical use cases.
Temporarily disable collection
If you wish to temporarily disable Analytics collection, such as to get
end-user consent before collecting data, you can set the value of
NO (Boolean) in your app's
Info.plist file. For example, viewed in the source XML:
To re-enable collection, such as after an end-user provides consent, call the
instance method of
Analytics. For example:
If you need to suspend collection again for any reason, you can call
and collection is suspended until you re-enable it. The value set by the
setAnalyticsCollectionEnabled method persists across app executions and
overrides the value for
FIREBASE_ANALYTICS_COLLECTION_ENABLED in your app's
Info.plist file. Once you set a value for
Analytics collection remains in that state until
is called again, even if a user closes and re-opens your app.
Permanently deactivate collection
If you need to deactivate Analytics collection permanently in a version of your
YES (Boolean) in your
app's Info.plist file. Setting
YES (Boolean) takes priority over any values for
FIREBASE_ANALYTICS_COLLECTION_ENABLED in your app's Info.plist as well as any
values set with
To re-enable collection, remove
your Info.plist. Setting
(Boolean) has no effect and results in the same behavior as not having
FIREBASE_ANALYTICS_COLLECTION_DEACTIVATED set in your Info.plist file.
Disable IDFA collection
If you wish to disable collection of the IDFA (Advertising Identifier) in your iOS app, ensure that the AdSupport framework is not included in your app.
Disable IDFV collection
If you wish to disable collection of the IDFV (Identifier for Vendor) in your
iOS app, set the value of
(Boolean) in your app's Info.plist file.
Configure the use of Analytics data
Disable personalized advertising features
If you have linked your Google Analytics project to an ads account or
otherwise enabled an ads integration, or opted into
your Analytics data may be eligible for use in personalized advertising.
This means for instance, that you may use collected events such as
to create and deploy audience lists for remarketing unless you indicate that
such data is not available for personalized advertising.
To programmatically control whether a user's Analytics data should be used for personalized advertising, set the appropriate default behavior in the app's AndroidManifest.xml file, and then use the methods described below to override that default behavior.
To set the default personalized advertising behavior, set the value of
in your app's Info.plist file.
Re-enable peronalized advertising features
To re-enable personalized advertising features for a user at run-time, such as
after an end-user provides consent, use the
method as shown below:
Analytics.setUserProperty("true", forName: AnalyticsUserPropertyAllowAdPersonalizationSignals)
[FIRAnalytics setUserPropertyString:@"YES" forName:kFIRUserPropertyAllowAdPersonalizationSignals];
If you have chosen to temporarily disable analytics collection (for example, until an end-user provides consent), and you want to control personalized advertising features upon re-enabling analytics collection for a user, ensure that your call to specify this setting precedes your call to re-enable analytics collection. For example:
Analytics.setUserProperty(..., forName: AnalyticsUserPropertyAllowAdPersonalizationSignals) Analytics.setAnalyticsCollectionEnabled(true)
[FIRAnalytics setUserPropertyString:... forName:kFIRUserPropertyAllowAdPersonalizationSignals]; [FIRAnalytics setAnalyticsCollectionEnabled:YES];
Confirming your settings
When ad personalization signals have been disabled for a user via one of the mechanisms defined above, subsequent event bundles logged from that user's device will contain a user property named "non_personalized_ads" with a value of 1 to indicate that events in that bundle are not available for personalized advertising. Disabling personalized advertising does not affect the use of the data for measurement purposes, including reporting and attribution.
