You might find someone, but otherwise you’re really just better off letting it fade to obscurity. That’s a really crowded space with a very low cost of entry (development-wise). Unless there is something significantly novel that makes it stand out, there is no real value to anyone taking it over for you. If you’re that worried about your personal details, which Google already has (can’t I ring that bell), make your own second dev account and transfer the app or call any costs the price of the anonymity you seek.
