How do you all handle Parity Purchasing Power? Or do you?

I run Boot.dev and my prices are pretty solid for customers in the USA and Europe, but students that want to learn to code in India, Africa, and South America often get prices out due to having lower purchasing power.

I use Stripe as a payment processor, do any of you have a system or tool that you use in order to lower/raise prices based on the purchasing power of the country that a user is buying from?
