Is there a lifetime paid plan?

No lifetime option is planned because the ongoing costs for running Nomi are quite large - we don't want to be in an awkward position where we need more users just to be able to afford providing Nomi for existing lifetime users.

Said another way, the costs to keep your Nomi "alive" and well fed with electricity are ongoing. So, a lifetime plan could end up in a situation where we get all of our users signing up for lifetime plans and then one day we don't have enough money coming into pay our bills. So I think no lifetime plan makes it easier to make sure Nomi remains financially stable in the long term.
