Make Paid Access Follow Real Stripe Payments

A Login Screen Does Not Decide What Each Person May Do

A working login screen is only the first step. Compare two test accounts to find out whether one person can view or change another person’s information.

Stop Your App from Giving Away Passwords and Payment Keys

Your published app gives every visitor files needed to show its screens. Check that those files do not contain passwords, payment keys, or codes that can expose customer information or create charges.

Check What Your Live App Shares With Strangers

Make Sure Paid Features Open Only for Paying Customers

Hiding a paid button is not enough. Your app must check a trusted customer record before it creates a report, opens a lesson, sends a download, or performs another paid action.

A Hidden Admin Link Does Not Keep People Out
