It might just be me, but I find it confusing that the upgrade statement says "a one-time payment of $39" and then the first checkbox says "3 months of access".
Does this mean I pay $39 every quarter to continue access? In which case why is it a one-time payment?

Thanks for the great feedback. We've just pushed an update that tries to clarify by removing "One time payment" and removing the "every area of Quantblocks" language.
