I empty it every day in my EndOfDay housekeeping process.
I saw the Cache folder had a file named "viewer-reading-rates.json", I have no interest in such data, nor any plugins like Reading Goal that might collect such data.
If I uncheck EPUB in the Preferences->Behaviour->use viewer for: list, and let Windows start the viewer (ebook-viewer is my default program for EPUB) the viewer reading rate data is not collected, The viewer opens just as fast (maybe even faster), and I don't appear to lose any functionality I care about.
