Remove "gad" entries from WordPress Options Table?

I used this plugin for a while, but recently decided to uninstall it because I have been really using Google Analytics directly on the Google site instead of the plugin.

I uninstalled this plugin and it removed the plugin directory.

However, when i was recently looking at my WordPress SQL database, I noticed that there are dozens of entries that have “gad” in the name, and tons that are called “transient_gad_cache_xxxx” and “transient_timeout_gad_cache_xxx”.

Are these leftover from google analytics dashboard?
Can I just delete these entries from my wordpress options table and not cause any problems to my site?

Just trying to keep my wordpress database nice and “clean”.

Thanks.

Michael
