There is Google Analytics, Firebase and loads of other analytic services which can capture the user events on mobile hardware and send it to an online dashboard. But AFAIK, none of these services log the events against each user i.e. although i will have a overview of user usage pattern of my app but when it comes to a particular user, I won't know for sure the events and clicks generated by him.
I understand this might be a bit of too much information for the services to handle and also might involve some rolling over some privacy fences.
But If i really feel compelled to record the events for a period of say 30 days, is there a suggested way to do it? Is there any service in the wild that provides this ?
