# Are my payment details secure?

_Category: Plans and billing_

Yes. Your card details go straight from the payment form to our payment processor, Braintree, a PayPal service. HelpCenter.io never stores your card number.

- We keep only the card type and its last four digits, or your PayPal email address, so you can see which method you're billed with.
- Braintree follows PCI DSS, the security standard for handling card data.
- Card payments can be confirmed with your bank through 3-D Secure.
- Only the account owner can see or change billing details.

For how we protect the rest of your account and content, see [Security and privacy at HelpCenter.io](https://self.helpcenter.io/content/security-and-privacy).
