Some features of the app are free to all users, some are to be paid for. The app makes it abundantly clear which feature fall into which category. The app provides you with the ability to pay for these features, if you wish to. Once you have paid for, or while are paying for subscribed-to premium features, you may have access to those items. That right is linked exclusively to the persona (username and password) that you create when you so pay / subscribe.
If the persona that you create is inactive for a substantial period of time (perhaps a year, or so), we may delete that persona. In which case that persona's rights are forfeit.
When you create a persona (username and password) so as to gain access to premium features, sensitive information is shared between you and a 3rd party authentication service. We do not know your password.
