A quick poll: how many of you would be offended or stop using the app if I set up Firebase Crashlytics in wasteof for Android? It would enable me to better diagnose bugs and crashes in the app, but would also mean that the app would technically contact Google's servers.
Nothing perceivable to you - but if there are any crashes or errors I'll get reports and will be able to fix bugs faster.
JavaScript error stack traces, device model, a few other things. No IP addresses or super identifiable information.
