A subscription is an instrument to make the app (thus benefits offered by the app) to work continuously, without any interruption or pause. The architecture of the app subscription is structured by Apple - and utilized by the 2ndLine app. Apple oversees and gathers payment from the user's Apple ID, i.e. the payment method associated with it. 

The subscription renews automatically once the user gives initial consent. It is the app that offers a subscription plan with various renewal (payment) frequencies like - week by week, month to month, and yearly.
