Audio, electronic, visual, thermal, olfactory, or similar information. 

Clarification: after a bit of research it seems the olfactory section pertains to CCPA California law, many places have olfactory in the privacy policy because it is required by the law. I can't believe we reached a point where we have to put olfactory in the privacy policy, but then again it won't be long before Smell-O-Vision becomes reality.

Also have a California ip you get a different privacy policy.
