When pledging, project creators will see your profile name, pledge amount, the reward tier and any add-ons you have selected, and your shipping country (if applicable). If the project is successfully funded, the project creator will also see the email address linked to your Kickstarter account, in case they need to contact you about your reward.
Is my pledge amount publicly displayed?
No, the amount of your pledge and the rewards you have selected are never publicly displayed — only the project creator will be able to see that information.
What if I want to pledge anonymously?
It isn’t possible to pledge anonymously, but if you'd prefer to change the name displayed on your Kickstarter profile, you can do so by going to the Edit profile tab under Settings and adding your preferred profile name.
