RoWarden now has paid plans. There's still a Free plan, and it's staying free. Running this costs money though, and I'd rather be upfront about how it's funded.
There's Free, Starter, Pro and Enterprise. Each one sets how many experiences you can add, how many staff each can have, and how far back analytics and the audit log go. The details are on the pricing page.
Subscriptions run through Stripe, so you can switch plans, update your card and download invoices from the billing page. I've also added license keys, which can be redeemed for plan time. They're handy for giveaways, or if you'd rather pay outside a subscription.
Nothing you've already set up gets removed. If you're over a limit on your plan, your data stays where it is. You just can't add more until you're back under it.
If anything looks wrong with billing on your account, message me before you do anything else and I'll sort it out.
