Thank you for this opportunity.
I have just activated a Premium subscription because I think your application is truly excellent (thank you for your work).
If possible, I need support about a change in my personal informations; can you tell me how to do this?
Thank you and keep up the good work!
Thanks for the nice words and your support 
I hope you are having a great time with Kurviger 
Ciao and welcome to Kurviger. What kind of support do you need in detail?
Thank you for your support; I need to change my login details (email and password).
Browse kurviger.com and login → Profilo → Azioni → Cambia email
There you can enter a new e-mail and confirm with the origin password. Once you did that, you can so the same for the password. Take care that you do this in two steps 
Thank you, very much!
