Maybe an older version of JD will work?
Sometimes people who distribute their software include tracking data that is used for marketing. Usually the tracking is "harmless" but still is intrusive. They probably were offered money to add this tracking (if this is the case).
That being said, if you can find an older version of JD that still works, it may not have this issue with it.
I don't use JD so I don't know how it works really. Just offering my technical view
Good luck!
P.S. If JD is a type of software that allows you to download video from tube sites etc, I use a Firefox addon called "Video DownloadHelper". This works perfect for me
