Analytic to get a list of player IDs for core/custom events

I am currently using GameAnalytics but not satisfied for our marketing purposes.

I got my own server saving some player details and IDs. Now I want to get the list of player IDs for core or custom events, so we can further promote for specific players.

Of course I can write code and record that on my server, but since I already record the events in analytic, that would greatly saved my time.

E.g:

• List of players who churn (stop playing) in last 7 days

• List of players who paid only once

• List of players who buy a item in game

• List of players who paid and leveled up to lv.50

• List of players who stuck (keep playing) lv.50 more than 10 times

• etc

GameAnalytics can only return the numbers/stats of the events. Any other analytic tools / servers like Kii can do the job?
