hey, you might wanna change your website a little bit then. it's not obvious right now.
i clicked on the link of your site, and the first box i saw said "9$/month". that's enough to click away (for me).
only after i did some more clicking and followed an external(!) link to the store it was obvious you can do a one-time purchase.
in a normal situation i would never have gotten to that point and would have clicked away immediately after seeing 9/month for a new product that still has to prove itself and doesn't have a big name behind it.
