It went without a name, an address or an identifier attached. It lands in the maker's inbox as an ordinary e-mail. Because nothing identified you there is no way to reply, so fixes and changes show up in the next release instead.
Messages are passed to an e-mail relay which turns them into an e-mail to the maker of Uncoil. Uncoil is an independent app made in the Netherlands. Full detail is in the privacy policy.
