No. Argent doesn't collect your billing information, we neither store it nor process it in any way.
As soon as you navigate into Add funds menu you start using our fiat-to-crypto partners widgets.
If you want to change/remove your billing details from the partner's system, you will need to reach out to the provider you used, either Wyre or Moonpay depending on your location:
- Wyre: email@example.com
- MoonPay: firstname.lastname@example.org
