Looks and works great. Couple of nitpicks:

1. in "Clear download cache" there is no space between "using" and the actual size so its "we are using21 KB of storage", or, after cleanup: "We are usingZero KB of storage"
2. I would rename "Flush" to "Everything" 2b) Maybe we could allow selecting / defining number of days (with comment "0 means everything" below the input field -- just an idea)

It would be possible to let users select no. of days but we would need to "rewrite" UI in some way to use stepper or slider and some other view to present them instead of just "menu". Initially, I've not implemented that, so for now just added a way to clean up metadata, but adding this new view with a slider could be a good idea.

Naming should be fixed.

Thank you. And selecting timeframe is just a side idea ("something for the future"). I think it can be closed.
