Data leaks after enabling and then disabling Analytics

[uson1x]

[REQUIRED] Step 1: Describe your environment

• Xcode version: Version 11.5 (11E608c)
• Firebase SDK version: 6.26.0
• Firebase Component: Analytics or Core
• Component version: 6.26.0
• Installation method: CocoaPods

[REQUIRED] Step 2: Describe the problem

In our app we want to dynamically turn on/off Firebase Analytics. Some of our clients don't want any information to be sent to third-parties. Some clients are ok with that. And we want to keep Firebase Analytics enabled for those.

We tried to implement such cut-off disabling functionality. But in our tests, if you first configure FIRApp+enable analytics and then disable+delete the FIRApp, some information is still sent to firebaselogging-pa.googleapis.com/app-measurement.com.

Is that a bug? Is there more reliable way to dynamically enable/disable Firebase/Analytics?

Thank you!

Steps to reproduce:

1. Enable Analytics and configure the app

   Analytics.setAnalyticsCollectionEnabled(true)
   FirebaseApp.configure()
   FirebaseApp.app()?.isDataCollectionDefaultEnabled = true

2. Disable analytics and delete the app

   Analytics.resetAnalyticsData()
   Analytics.setAnalyticsCollectionEnabled(false)
   FirebaseApp.app()?.isDataCollectionDefaultEnabled = false
   FirebaseApp.app()?.delete({ (success) in  })

3. Go to home screen.

4. In network traffic I see requests like GET https://app-measurement.com/config/app/1:<some_id>:ios:<some_id>?platform=ios&app_instance_id=<some_id>&gmp_version=60600 HTTP/2.0 or POST https://firebaselogging-pa.googleapis.com/v1/firelog/legacy/batchlog HTTP/2.0 with a long body.

We also have FirebaseScreenReportingEnabled: NO set in our app's .plist file.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Can you please provide some debug log?

[uson1x]

Sure, here it is:

First, app was launched without configuring Firebase, called these two methods

Analytics.resetAnalyticsData()
Analytics.setAnalyticsCollectionEnabled(false)

FirebaseApp.configure()
FirebaseApp.app()?.isDataCollectionDefaultEnabled = true

[uson1x]

Just FYI: our clients agreed to keep Crashlytics always on, so we will not be disabling Firebase completely at any point.

The issue is no longer relevant for us, please, feel free to close if you don't plan to investigate further.

[ryanwilson]

Thanks for the update - it's important that we do keep this open and investigate to ensure we understand what's going on here and stop it since this shouldn't be happening.

[shengyang998]

Hello, is there any investigation going on? I'm facing the same issue here.

Unlike @uson1x , unfortunately, this is an unacceptable behavior due to our privacy policy.

If it cannot be fix in a reasonable time, maybe a removal of firebase framework shall be necessary.

Update:

Same issue means: The network request (to firebaselogging-pa.googleapis.com) exists even In an app that does not even @import Firebase; and call [FIRApp configure]method, all I've done is integrated the framework.

I do use strings command search the binary, and found something like this:

https://firebaselogging.googleapis.com/v0cc/log/logging-pa.googleapis.com/v1/firelog/legacy/batchttps://crashlyticsreports-pa.googleapis.com/v1/firelog/legacy/

What kind of black magic have you done in binary framework, for there is nothing in source code...

Please respond when there is something new.

[volmus]

@ryanwilson Any updates on this? We're facing the same issue.

As @shengyang998 mentions, this is also unacceptable for us due to our privacy policy.

[ryanwilson]

Hey folks, thanks for commenting. I'll get a more detailed answer soon, but a few things to note here:

The APIs that show crashlyticsreport-pa are for Crashlytics reporting.

Re: the strings not being found in the source code, they're there just harder to find to avoid abuse from bots scanning GitHub: https://github.com/firebase/firebase-ios-sdk/blob/fa7b3f9e7e247edfdd79ef9054a5112285c88d28/GoogleDataTransport/GDTCCTLibrary/GDTCCTUploader.m#L115-L164

Question for both @shengyang998 and @volmus - can you please provide the exact API calls in the order you're making them, and the issue you're seeing? The original post had a variety of enabling, disabling, and deleting the FirebaseApp which can affect the runtime flags. It'd be helpful having an exact setup that we can replicate to ensure your issue is addressed and investigated properly. That, and the SDK version you're using since this was reported a few versions ago. Thanks!

[shengyang998]

Thank you for your information @ryanwilson . I will dig deeper with those.

In my case: The exact API is none.

We use Cocoapods to integrate Firebase framework, and configure it with :configurations => ['AppStore']. However, we did not exclude it from compiling. The version is:

Firebase/Analytics (6.29.0)
Firebase/Core (6.29.0)

The tested app is built with Release and not AppStore macro is defined. We did not even import or access any Firebase class, and voila, there the request it is.

Since I didn't import it, so the network request maybe inside of some +load or +initialize method? Since I couldn't reproduce it (reported by others), I consider it is some kind of multi-threading issue?

Hope these information could help.

[ryanwilson]

Thanks for the quick reply @shengyang998.

To confirm, you don't call FirebaseApp.configure(), correct? There are definitely calls inside of +load that are needed for Analytics to be able to get helpful Analytics data for your product. If you need to ensure that analytics aren't being sent to FirebaseAnalytics during startup, please use the FIREBASE_ANALYTICS_COLLECTION_ENABLED Info.plist key and set it to false. You'll likely still see local logs but should not see any networking from the Analytics SDK itself. If you do see networking with that key disabled, please let us know what calls are being made and that should get resolved.

Note: the above controls FirebaseAnalytics specifically, not all of Firebase. If you want to disable all automatic data collection for Firebase at startup, use the FirebaseDataCollectionDefaultEnabled key in your Info.plist. Then, you can enable it at runtime after a user has opted in using the dataCollectionDefaultEnabled flag on FirebaseApp.

Edit: the other option is - if you have no intention of calling any Firebase APIs and don't want Analytics to ever be collected in a target, the safest bet is always to remove the code entirely.

[shengyang998]

Thanks @ryanwilson I will try those keys.

Yes, I didn't call FirebaseApp.configure()

To be clear, if I want to disable all automatic network request for Firebase and FirebaseAnalytics, I need to set FirebaseDataCollectionDefaultEnabled to false in Info.plist. And it won't cause automatic data collection if FirebaseDataCollectionDefaultEnabled is set to false. If I want to enable data collection, I should set the property dataCollectionDefaultEnabled to true.

Is that correct? Or should I use both keys in Info.plist?

[ryanwilson]

Correct, the global key FirebaseDataCollectionDefaultEnabled is likely what you want. It is newer and controls all automatic data collection in Firebase SDKs, not just the Firebase Analytics SDK. Then once a user has opted in, or whatever control you're using, you can set the dataCollectionDefaultEnabled runtime property to true and it will persist across app launches for that device.

[shengyang998]

Thanks a lot, it seems to me that the issue is been fixed. At least I hope so.

[eikSchli]

In our project we ran into the same issue.

We want to use the Firebase Remoteconfig and still be able to turn tracking (user behavior statistics) dynamically on and off. So we cannot avoid using „FirebaseApp.configure()“.

After the newest updates on this Thread, we made following adjustments to our code:

In the info.plist, we set :

• FirebaseDataCollectionDefaultEnabled: false

as our default setting. If the user wants to allow tracking of „User Statistics“, we changed the value at runtime, like mentioned above:

static func initialize() // Called at appstart
    {
        if Features.fireBaseSupport        {
            FirebaseApp.configure()
            FirebaseApp.app()!.isDataCollectionDefaultEnabled = false      // here: turn it off again

            FirebaseConfiguration.shared.setLoggerLevel(.min)

            Performance.sharedInstance().isDataCollectionEnabled = false
            Performance.sharedInstance().isInstrumentationEnabled = false
            Analytics.setAnalyticsCollectionEnabled(false)

            if(AnalyticsTracker.isEnabled())
            {
                FirebaseApp.app()!.isDataCollectionDefaultEnabled = true                  //here: turn it on

                Performance.sharedInstance().isDataCollectionEnabled=true
                Performance.sharedInstance().isInstrumentationEnabled=true
                Analytics.setAnalyticsCollectionEnabled(true)

                let token = PushManager.sharedInstance.userPushToken;
                if (token != "")
                {
                    Crashlytics.sharedInstance().setUserIdentifier(token)
                }
            }
        }
    }

The problem still seems unsolved, because we ran into following bahaviour:

• After a fresh installation, there is just one call of "app-measurement.com“ – no matter the configuration
  • Something already seems to be going wrong here

Operational:

• Firstly, tracking of „User-statiscs“ is deactivated by default

  • Except for the point above, this works as expected. No more leaks here

• Secondly, the user activates „User-statistics“

  • Our tracking works as expected and we see the results in the Firebase console
  • We can see, as expected, traffic of: -- "app-measurement.com“ -- "firebaselogging.googleapis.com“ -- "firebaselogging-pa.googleapis.com“

• Thirdly – and here is another Problem – the user deativates „User-statics“ again.

  • This should turn off all unexpected traffic
  • BUT, there are still calls to bee seen from: -- "firebaselogging.googleapis.com“ -- "firebaselogging-pa.googleapis.com

As @ryanwilson mentioned before „[…] you can set the dataCollectionDefaultEnabled runtime property to true and it will persist across app launches for that device.“ Does that mean, it is not possible to turn it off again? We believe, this should not be the case. And in this constalation, is still unacceptable for us due to our privacy policy. We connot force our users to reinstall the app every time they turn this setting on and off again.

Is this intentional behavior or are there any other solutions to this?

Thanks in advance.

Adding a “me too” to this bug. Specifically, I’m seeing an unexplained network call to app-measurement.com. [FIRApp configure] has not been called, and this is in the app’s Info.plist:

<key>FIREBASE_ANALYTICS_COLLECTION_ENABLED</key>
    <false/>

This is a violation of our privacy policy. Unfortunately if this isn’t fixed before our next update, we’ll be pulling Firebase from the app.

Filed internal Analytics issue b/168251939

[htcgh]

Firebase 6.33.0 includes changes to address this issue in Analytics. Please re-open this issue if it persists after updating.

[eikSchli]

After updating our Firebase Library to 6.33.0, the problem still persists. Especially after enabling and re-disabling DataCollection and AnalyticsCollection.

[htcgh]

@eikSchli Apologies for the delay. Is this issue still happening in Firebase 7, and if so, which network calls are being triggered while data/analytics collection is disabled?

[haozhutw]

@htcgh We are using Firebase 7.4.0, but still encounter this issue.

We firstly setup Firebase with FirebaseApp.configure() at app launch, then if the user opt out the analytics function on a consent management screen, we disable the Firebase analytics by setting:

FirebaseApp.app()!.isDataCollectionDefaultEnabled = false   
FirebaseConfiguration.shared.setLoggerLevel(.min)
Performance.sharedInstance().isDataCollectionEnabled = false
Performance.sharedInstance().isInstrumentationEnabled = false
Analytics.setAnalyticsCollectionEnabled(false)

But firebaselogging-pa.googleapis.com is still triggered, something wrong with our implementation?

[ryanwilson]

@haozhutw can you please share more information about this, specifically:

• Which products are you using?
• What Xcode/iOS version are you using?
• Is this reproducible in Firebase 8.0.0 (just released)?
• What is the full URL that the data is being sent to?
• Does this reproduce in our quickstart application with the code above?

Note that the runtime flags do persist data and override any previous settings, so if you are also using a product like Crashlytics and have previously set the Crashlytics specific flag to enabled, it will still make requests.

Without knowing the full list of products you're using and a reproducible case (either within your app or ideally our quickstarts) we won't be able to make further progress on this.

Thanks!

Hey @uson1x. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Sorry for the late reply! To answer your questions one by one:

• I'm using Firebase Analytics, crashlytics, performance monitor and dynamic links
• Xcode v12.4, iOS 11.0 and above
• Haven't tried Firebase 8.0.0 yet, I can only install Firebase 7.11.0 when I added previous comment at that time because v7.11.0 is the latest on CocoaPods.
• I didn't notice the full URL, will send you later if this issue happens again.
• I haven't tried the quick start application, but all of them have the same initialization logic with [FIRApp configure], is this the root cause? Does the configure method send any api request to Firebase through firebaselogging-pa.googleapis.com?

[swrobel]

I'm seeing this with Firebase 8.0.0 on an iOS React Native app that only uses Cloud Messaging. My app is sending tons of pings to Firebase logging:

[morganchen12]

@swrobel the logs you're seeing are general purpose non-Analytics logs used by the Firebase team for metrics collection. If you don't have the Analytics SDK in your app, you don't have to worry about this issue.

[swrobel]

you don't have to worry about this issue.

I don't have to worry about unexpected network requests every 30 seconds 🤔? Are you saying there's absolutely no way to disable this?

[paulb777]

@swrobel Do you have the relevant flags initialized like described above?

[maksymmalyhin]

@haozhutw Setting FirebaseApp.app()?.isDataCollectionDefaultEnabled = false should be enough to prevent requests to firebaselogging-pa.googleapis.com in Firebase 8.1.0. The caveat here is that Firebase Performance may trigger the requests before the flag is set (as a part of FirebaseApp.config()). It means that a request may still be sent during the first app launch. To set this flag earlier you can add a key FirebaseDataCollectionDefaultEnabled with value NO to your app Info.plist as suggested in the docs.

Could you please try adding FirebaseDataCollectionDefaultEnabled and let us know the result? If you still see the requests could you please provide a sample project to reproduce the issue.

Also, I would probably suggest to create a separate ticket for your issue as it looks quite different from the current one.

Since there haven't been any recent updates here, I am going to close this issue.

@uson1x if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
