Email support@getwishlist.app and describe what happened. Wishlist is made by one person, so replies usually take a day or two rather than minutes.
It helps to include which device you were using, what you were trying to do, and what you saw instead.
Signing up never sets a password. You enter your email address and we send you a sign-in link, with a short code you can type back in instead. If neither arrives, check your spam folder first, then try again. Codes expire, so always use the most recent one. If your account already has a password, the sign-in screen offers it as another way in.
Nothing is shared until you share it. A list is private until you either make it visible to friends or send someone its link. When somebody reserves a gift from your list, it stays hidden from you until you reveal the list. After the list's date, Thank offers to show who reserved what. A list with no date can be revealed at any time. If you change a list away from "Anyone with the link", the old link stops working.
You can delete your account from inside the app, on any platform, without emailing anybody. Open your account settings and choose to delete your account. You will be shown exactly what gets destroyed before anything happens, and it cannot be undone.
