Regarding credit card information and Premium membership

Just looking for someone more experienced in this field of chess.com to answer me

I'm pretty sure credit card info remains once you first enter it for Free Trial / Gift / Buying Premium etc... and I have a couple questions about this

1. Is this per account? How would this work with multiple devices or accounts?

2. Can you remove that data? I'm pretty sure you need do ask Support to do that, right?

3. Can you edit that information somewhere?

I've had like a couple more questions prior to writing but I've just completely forgot them now. I'll add them on later if I remember. Thanks to anyone who can come up with an answer (like, a useful one, of course)!

This seems ominous yet disregardable

The site doesn't store credit card details, but does have an authorization with the payment processor. So, your card details can't be retrieved from the site.

I believe support can remove the authorization that's stored but you can't. You can add a new payment option but I don't see anywhere to edit the existing information.

I let my friend use my card for free trial but he wasn't able to - I guess due to the same card being used chess.com thought that was my own other acc or something, so he ended up using his paypal for free trial.

Money

bruh
