I use Firebase Analytics and Crash Reporting services. These services may use device identifiers (e.g. Android Advertising ID, Advertising Identifier, Instance ID) to generate analytics and crash reports.

For more detailed information on what data is collected in Analytics see - Analytics keeps data associated to ID for 60 days and keeps aggregate reporting data without automatic expiration. Crash Reporting retains crash stack traces for 180 days.

You can opt-out of these services by uninstalling the app.
