Hi @h1234

Log in at cpanel.hostinger.com with your credentials you have used for the purchase.

Note: 000webhost and our premium services (Hostinger) has two different user systems

it is posible to transfer 000webhost’s dns and file to Hostinger

You can transfer your files to hostnger easily. Just ask any live chat support member. But you can’t transfer 000webhost domain to hostinger

i am not able to live chat on 000webhost, it show upgrade option.
it is posible to upgrade 000webhost account, because it already configure with our game, game going to release tomorrow. and refund from hostinger.

cpanel.hostinger.com, then login, follos the below tutorial
