The domain was purchased from Hostinger and it’s getting annoying to me how I must ask for help here every time I decide to put up a website from 000webhost when the domain was purchased from Hostinger. The last time I did this, I got the branding taken off-hopefully that concept is still a thing (buy domain from Hostinger = you can remove the branding)
If you purchase your domain on 000webhost.com using the provided menu then branding should be disabled.
If you make your way over to Hostinger and purchase a domain then no the branding is not disabled by standard but I will check now if this can be done for you individually.
