When users create an account through login.vuplex.com/signup, Vuplex stores the user's email address and a cryptographic hash the password that the user provides. When a user adds additional users to their account, the same is done for those additional users.
Vuplex store checkout (store.vuplex.com/checkout) uses Stripe and PayPal to collect payments. Stripe and PayPal collect payment information directly from users (e.g. credit card information) and pass that information directly to their own servers. So, Vuplex never sees or stores personal card information. Instead, Stripe and PayPal provide Vuplex with an ID that represents an order, and Vuplex stores that order ID.
