Any website that you use could store all kinds of data about you without even telling you. Not to mention your ISP, who knows everything! At least Google is making it clear via Google History that they do have the means to do it.

Assuming no MITM attack, yes. Of course they can still see what hosts you're connecting to for your HTTPS sessions, just not the content going back and forth.
