Does RoundUp App need my personal information if I am an admin on my nonprofit organization’s RoundUp account?

RoundUp App doesn't require personal information, but Stripe will ask you for it.

No, RoundUp App doesn’t need any personal information, but we use Stripe as our third-party credit card processing company, so if you are creating a Stripe account while you are creating a RoundUp App account, you will see their process requires some personal information collection. RoundUp App will not have access to any information collected by Stripe.
