About Stripe
Stripe is a payment services provider used by millions of merchants, ranging from very large companies like Amazon and Apple to innumerable small businesses. If you make purchases online, you’ve likely used Stripe at some point. It’s comparable to PayPal and Square, which may be more readily recognized by consumers.
The most important security information for you to know is that as the merchant, I don’t have access to your credit card information.
