How secure is Leaky Paywall?
If you are running Leaky Paywall with our Stripe integration we lean on the security measures of WordPress core, Stripe, and your hosting setup.
Leaky Paywall simply adds meta information to the WP user. We use all the standard WP login functionality so the subscriber is simply a logged in WP user.
Payments are securely sent to Stripe (assuming your host has an SSL installed) and Stripe manages the transaction and credit card info.
If we integrate with a 3rd party CRM we send the encrypted data (via SSL) to the CRM provider and they manage your customer info. In this case Leaky Paywall manages your content access and the CRM becomes your source of customer truth.

The same would apply for PayPal as they would store all your transaction data.
