Your email will not be shared with the person you are reporting. Reports go to our admin team, not to the developer. If you report is something that needs to be shared with the developer (eg. you are trying to trouble shoot a bug), then it may be forwarded to them by someone on our team.
Furthermore, why does itch even ask for my email address, if I’m already logged in?
The field is pre-filled with your account’s email address if you are logged in. If you with to be contacted at another address then you can change the email address there.
