android - How is the Firebase Remote Config rate limit counted?

Question

I am using Firebase Remote Config to store a secret key for a mobile app ( I do not want to include in client app due to security problems).

The problem is I know that fetching config from server many times in a short period of time can throw a throttling exception. In a production app there is a limit of 5 requests per hour but I do not know if this limit is count per user or globally.

This is the code I have:

//first search cached result, if present
    String key = FirebaseRemoteConfig.getInstance().getString("key");
    if(key != null && !key.isEmpty()){
        setKeyAndGoHome(key);
    }else {
        //no key present, let's fetch it from config
        FirebaseRemoteConfig.getInstance().fetch().addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if(task.isSuccessful()){
                    FirebaseRemoteConfig.getInstance().activateFetched();
                    //key is cached 12 hours
                    String key = FirebaseRemoteConfig.getInstance().getString("key");
                    setKeyAndGoHome(key); 
                } else {
                    //this can happen due to a throttling exception
                }

            }
        });
    }

This is very important because without this key my app can not work. I need to know if throttling exception condition can be reached.

Do you know how is the limit counted?

Thanks.
