I have disabled Web & App activity, so I presume that means Google doesn't save my history of websites against my account. They still see the data when I go to the website, but they don't save it?
The other thing I have heard but cannot verify is that Google scans your photos you load and use that to build data, I don't see any of that in the activity either to disable.
