1. The file you see itself is the configuration recorded when the App starts, including information such as the ID used by the service. There is no private data.
    This configuration is only used when alert service is enabled. It doesn't keep generating. If you delete it without restarting the App, it won't be produced again.
    If you don't enable alert service, it won't connect with Google and won't report this information.

  2. The only situation in which data may be collected by third parties is when a user manually turns on the alert cloud service. The user's mobile phone ID will be obtained by the third party to push messages.
