Q: How can I get credit card information off of my iPhone

Hi Jessicalovesjosh,

Welcome to the Apple Support Communities!

I understand you want to remove your credit card from iTunes. You can either do this on your iPhone itself or from the iTunes application on your computer. The attached article has the steps to do both.

Change or remove your payment information from your iTunes Store account (Apple ID)

Have a great day,
