SUMMARY

I would really like to donate via debit card but the payment processor settings on your site are way too strict. Apart from my credit card details they insist on getting my email address, my phone number and my home address. Insult to injury: although the request comes from an EU IP address there's a complete disregard for GDPR issues. 

STEPS TO REPRODUCE
1. Follow the Plasma pop-up link for donation https://kde.org/donate/?app=plasma-donation-request-notification
2. Click on "Donate" from the "One-time donations" panel
3. On "Donate to K Desktop Environment e.V. " Paypal page click on "Donate with Debit or Credit Card"
4. In the next page fill in "Write a note (Optional)" "Card number" "Expires" "Security code" "Given name" "Last name" 
5. Click "Agree & Donate Now"

OBSERVED RESULT

Paypal processor page insists (by changing border colors) that  

Address line 1
Mailing address is required.
 
City
City is required.
 
Phone number
Phone number is required.
 
Email
Email is required.

EXPECTED RESULT

Payment processor should have allowed me to pay the same way I pay other goods which is without making other than necessary fields a requirement. 

Payment processor should have enabled a form where I should have been able to chose how my personal data is processed.
