Firebase Crashlytics

Firebase Crashlytics is a platform that allows developers to track crashes:

Firebase Crashlytics is a lightweight, realtime crash reporter that helps you track, prioritize, and fix stability issues that erode your app quality. Crashlytics saves you troubleshooting time by intelligently grouping crashes and highlighting the circumstances that lead up to them.

Our issue with Crashlytics is that it is often implemented to track more, often tracking and submitting even every application start:

Crashlytics automatically starts collecting crash reports as soon as you add the SDK, but you can also customize your setup by adding opt-in reporting, logs, keys, and even tracking of non-fatal errors.

It has been added to Spybot Anti-Beacon 3.4.
