--- Comment #5 from Pedro V <voidpointertonull+bugskdeorg at gmail.com> ---
I'm not convinced that this is a duplicate, at least as I see:

This report describes the problem that Okular keeps on leaking metadata,
breaking down encryption boundaries, and ignoring the user's privacy settings
regarding remembering recent files. The solution is not necessarily hashing,
but there's definitely a problem that's a bug, even a security issue, and
definitely not a wishlist matter.

Bug 249572 is a wishlist item for improved metadata storage control. While as a
superset that can also solve this issue, it wants to generally do a whole lot
more than what would be enough here.

I believe this should be reopened, and set to be a regular bug with higher
priority.
I'm not even sure why is Okular one of the few programs that tracks usage by
default, but doesn't even have an option to disable that often undesired
behavior.
