GDPR and delete account data

I would like to know if it is possible which data are deleted when account is deleted under GDPR => Permanent Delete.

Thanks in advance

Sure. Please see implementtion of this method here

Thanks for your reply. I just tested it by going into customer and click on GDPR/Permanent Delete.
I then run the following SQL scripts

SELECT * FROM [dbo].Customer WHERE Id = 1278
SELECT * FROM [dbo].[CustomerAddresses] WHERE Customer_Id = 1278
SELECT * FROM [dbo].CustomerPassword WHERE CustomerId = 1278
SELECT * FROM [dbo].GdprLog WHERE CustomerId = 1278
SELECT * FROM [dbo].[Order] WHERE CustomerId = 1278
SELECT * FROM [dbo].[ShoppingCartItem] WHERE CustomerId = 1278

and I see that only CustomerAddresses were deleted and Customer table some fields are set to empty.
All other tables have data of the deleted account.
