There is, it’s right here:
The main issue is that as you pointed, out, you can’t cherry pick which profile info you want, like “full name”, you get the full package of public user info:
- view your name, public profile URL, and photo
- view your gender
- view your country, language, and timezone
… which IMO is not that onerous, and if it is.. hey, see above image 
That’s why I never, ever will have a Facebook account.
That said I don’t object to putting “we will only use name and email” somewhere in the UI, just don’t really see room for it without adding clutter at the moment.
