Do I need permission for services like Fabric Crashlytics in iOS?

Question

I have developed an app which has nice download figures, however when I look at App Statistics on iTunes Connect, I can see that it does crash a couple of times. I'd like to take that out by using a service like Fabric Crashlytics.

What I'm wondering though, and what I can't find a lot of info about, is whether I need to ask my users permission to do this? In the end of the day, the service does send data from their device to a server. Can I just do this in the background or do I need to ask for permission?

Answer 1

As per Crashlytics terms https://try.crashlytics.com/terms/

What information does Crashlytics collect from End Users?

The Services automatically collect certain information that does not personally identify End Users who access or use mobile applications that use the Services. This information includes, but is not limited to, device state information, unique device identifiers, device hardware and OS information, information relating to how an application functions, and the physical location of a device at the time of a crash.

Answer 2

It is not mandatory, but you should ask your users to collect these datas. Here you can see how to do this.

Edit:

Go here to select the app you want to add the dialog to and then click on "Enable Privacy Prompt" in the top left corner.
