When you create an account on Seed&Spark, your profile will be viewable to the general public. This will include your name, city, your projects, and projects you've supported.
You can view your public profile by logging into your account, and selecting "View Profile" in the dropdown menu on the upper right, after hovering over your name.
You can make your user profile private by adjusting the privacy settings on your Seed&Spark account when you're logged in.
