If a project is still live, you can cancel your pledge before it ends. However, once a successful project has ended, and collection has started, it is no longer possible to cancel your pledge.
All money raised goes directly to the creator and is managed by the creator, minus a 5% fee collected by Kickstarter. If you’re interested in having your pledge refunded, you’ll need to reach out to the creator directly. To message a creator, visit the project page and click on the creator's profile name. This will open their bio page where you can then click the "Contact me" button.
If a creator issues you a refund on Kickstarter, this will be automatically applied to the card you originally pledged with. It may take up to two weeks for the refund to appear back on your card. If you don’t see your refund after a couple of weeks we recommend reaching out to your bank for assistance, as this process varies from one financial institution to another.
