Is there a site that tracks all flights? Some of my flights are tracked on sites like Flightradar24 and others are not, regardless of flight plans being opened and closed. It would be nice to go to a website that tracks all flights, so I can review the flight dynamics after I land.

I am interested in a website that provides this service, not an app (I have had limited success with these).
No, there will always be flights that are private, or for any other reason not traceable.
