We're in the process of adding a "Close my account" feature which will allow you to deactivate your account and close it.

As of now, all you have to do is reach out to us on Profile>Other>Help and let us know that you want to close your account and we'll do it for you. You'll know your account has been deactivated after we've seen your message and you wont be able to log in with the information you used to sign up with.
