How long will a pay per view customer be able to see the content?

Hello,

I have just installed the Pay per View plugin and wonder how long a paid customer (pay per view, not subscription) will be able to actually see the content?

How is the accessible duration controlled (e.g. via a cookie)?

In the optimal case a user should be able to see the post content for quite a while (e.g. 48 hours) and not only for one view.

Thank you very much.

Best regards,
Alex
