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.

They removed it, archived here: https://archive.ph/YYBuJ
Also have a California ip you get a different privacy policy.
It is always better to do that shit with a separate gizmo. Ideally, something computery enough that it will not betray you, or cheap enough that you can take a hammer to it when it does.
