# Payment methods

> Paying by card or cryptocurrency, what appears on your statement, and keeping it private.

## Cards

You can pay with major credit and debit cards, including Visa and Mastercard. Card payments are handled by our payment processor on its secure checkout page: **we never see or store your full card number.**

Your bank may ask you to confirm the payment in its app or with a code (3-D Secure). That's normal.

## Cryptocurrency

You can also pay with cryptocurrency, through NOWPayments. Crypto payments can't be charged again automatically, so plans bought this way are **paid in advance** for 30 days or a year and **don't renew**. Buying again adds the time on.

Send the exact amount shown, on the network shown, before the payment window closes. If you send less, the payment won't complete; email [billing@sinfully.ai](mailto:billing@sinfully.ai) with the transaction ID and we'll help.

## What appears on your statement

Your statement shows the name of our payment processor or a neutral billing descriptor, not the names of any companions or anything explicit. Your receipt email tells you exactly what to look for.

## Currency

Prices are set in US dollars. If your card is in another currency, your bank converts the amount and may add a fee.

## Changing your card

When you buy again or renew, the checkout lets you use a different card. If a renewal fails because your card has expired, see [Your payment didn't go through](https://sinfully.ai/help/payment-declined).
