Beta Pricing (Limited Availability): $19/month, locked in forever for qualifying beta members, including a 14-day free trial and access to all current and future modules.

Future Pricing: PN23 will introduce tiered subscription plans at higher price points as the platform grows. Beta members retain their $19/month rate indefinitely as long as they maintain continuous service.

All payments are processed securely through Stripe. Your subscription automatically renews each month. You authorize us to charge your payment method on a recurring basis for monthly subscription fees, applicable taxes, and any other charges you incur.

If a payment fails, we will attempt to process it again. Repeated failures may result in suspension or cancellation of your subscription. You remain responsible for any uncollected amounts.

4.4 Pricing Changes

Beta pricing of $19/month is locked in forever for qualifying subscribers as long as they maintain continuous service. If you cancel and re-subscribe, you will be charged the current standard rate at that time.
