Your email will never be used to flood you with messages (maximum once a month). Your card details are encrypted so no one can use them. If you’re still concerned about security, please read this piece before proceeding to checkout.
TLDR: Both Stripe and PayPal take security seriously. At the core, they’re both very stable and secure platforms. Let’s talk about how they’re different, and how Stripe intrinsically encourages good security.
Stripe’s killer feature when they first launched was Stripe.js. When you use Stripe.js on your website, the credit card data entered into your payment form is never sent to your server. Instead, the data is sent directly to Stripe.
If you follow the normal flow with Stripe, you’ll just automatically store your cards in their vault. You’ll never touch the sensitive data. This encourages good security.
