Axel here, one of the builders of Epilude. Appreciate the question.

Whilst the subscription plans work as any normal SaaS subscription, we're fond of pay-once models that don't tie you into continuing to pay for a product unless you feel you continue to get value from the updates we're shipping to the product.

We currently think of model updates as part of the updates that we continuously ship to make to the product better, and so we include model updates in the "one year of app updates" that come with the Pay Once option. At the moment, I think this approach makes sense, but we're of course open to feedback.

In any case, I'll update the info on the website to clarify this. Thanks for pointing it out.
