Personally I think you are making the right call avoiding subscriptions in a side hustle project like this.

Once subscriptions get involved you have to deal with a lot more complexity, churn metrics, refunds (more so than now because of people 'forgetting' to unsub), the stuff around do you pro-rata at subscription cancel or leave it running until date is reached, stripe makes that a little easier but its still a thing.

so yeah, good move imo.
