jCalc uses Stripe.com to securely collect, transmit, process and store your credit card information.

Stripe.com is a level 1 PCI certified payment service provider. And it is one of the top 5 payment service providers in the world.

jCalc does not collect, transmit, process or store credit card information on the jCalc server.

The credit card input form on the jCalc payment page is loaded directly from the Stripe server. And when you click "Pay", your information is submitted directly to Stripe over a secure SSL connection.

On the Stripe system, only the last 4 digits of your card number and expiry date are visible to a Stripe administrator.
