BackerKit surveys are coming!
2 months ago – Wed, Apr 10, 2024 at 03:02:02 PM


Soon, you’ll receive an email from us with a special link to your BackerKit survey. It’s essential to respond to your survey as quickly as possible since we need this information to fulfill your rewards.

You do not need to create a BackerKit account to fill out your survey. When you receive the survey invite email, click the survey link to respond. Answer the questions about your reward preferences, provide shipping information, and purchase add-on items if you like. You don’t have access to this survey link yet, but it will be available soon via email!

After you respond to your survey, you can go back later and change your responses at any time before we close the surveys and get our final counts.

Due to the volatility of shipping prices globally right now, shipping fees for this project will be calculated at a later date once we have the best estimates for everyone. We plan to enter & charge backers for shipping a month or two before fulfillment when we have better estimates of what it will cost to ship backers rewards. We will alert backers when shipping costs are finalized & before we charge your cards in your BackerKit survey. We will keep you informed all along the way!

If you need to review your information or pledge status, you can return to your survey by clicking the link in your survey email or requesting your survey link under "Lost your survey?" on our BackerKit project page at

If you used your Facebook credentials to log in to your crowdfunding account, the BackerKit survey is sent to the email address associated with your Facebook account. If you have another email address that you prefer to use, please contact support at

After surveys are sent, if you did not receive the email, and you Signed in with Apple ID, your email address might be a private relay email address. We can help locate your survey and update your email address, please message us or post a comment with your Backer ID or Pledge # found on your confirmation. You can learn more about your email hiding for your Apple ID here.
