Plasma 5.13 user actions tracking and indexing

Plasma tracks down all user activity and keeps records of everything the users do (what apps, files, URLs they use, open or visit, what they type and where all their files are located. From the privacy point of view it is very dangerous, as unauthorized access to logs or indexes will literally render you naked. Did anyone look at this issue (e.g. I cannot turn off the clipboard) - is there a clean way of disabling all those features, unnecessary from the point of view of a home user with still good memory?
