Give Foundation does not store your credit card numbers. To keep your credit card details secure is one of Give's top priorities. We make sure we protect the information you provide while making a donation. All of our platforms and APIs use TLS encryption with HSTS and Forward Secrecy for clients and browsers that support it. Our payment processing partners CCAvenue, Razorpay and Stripe have been certified to PCI DSS which is the most stringent level of certification available in the payments industry.
