Recurrent Payment with Pause/Start

Hello! We are a small mobile developers team from Kazakhstan. Nowadays I'm developing an alarm clock mobile app. We have the following concept of our application - User pays when he woke up late and can save money if woke up in time. We have a problem now, in terms of making great UX. To follow Apple Store rules we don`t have permission to use side payment providers, but in our case, we should use recurrent payments and we need a feature to pause payments by request. Please tell, us how can we develop this functionality and do not break up Apple rules?
