When creating or editing a wish in your wishlist, you can select the “Secret wish” option. Only you will be able to see this wish. You can make it public again at any time.
A secret wish is only visible in your profile. It will not be displayed to your friends when they visit your profile, or via the link to your wishlist.
A link to a secret wish sent to another person will not open. However, if you make the wish public again, the link will work again.
