Gmail does. All those services — to, say, find all the big emails you should delete or the important emails you should read — may, too. They may still read your mail, label it or move it around and get a hold of your contacts to boot.
Fortunately, Gmail not only remembers who you granted access, it makes it easy to find out and revoke all rights as well.
