It currently has no paying customers, verified revenue, production usage metrics, or established uptime history. Stripe and PayPal are not integrated. Payments are recorded manually. Email reminders require SMTP configuration and are manually triggered rather than automatically scheduled. The project has not undergone an independent security audit or production acceptance test.
