We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
May implement local payment support via OmniPay library (http://omnipay.thephpleague.com/gateways/official/). If we do that put a note in other payment gateway issues that OmniPay supports as now supporting local payments (but payment button work may still be desired), and document.
