I want to keep track of everything we watch… forever. Do I have to upgrade to Lifetime to get this functionality (with the Dash app)? Or is it available in the free version?
I am willing to upgrade if that will get me this feature, but will the logs retain all usage data indefinitely or will I have to periodically back up the log files so that information does not get deleted, overwritten, etc.?
Based on the available filters (e.g. Last 7 Days, Last 30 Days, Last 90 Days, Last Year, All Time), I take it Plex is not deleting any playback records.
The filter is usually in the top-right of the related views/hubs/tables (see “Play History” in the support article linked above). In the “Full History”, the time is one of the filters above the tabular playback history.
The screenshots you can see in the support are based on Plex Web or the Plex Desktop clients (Plex for Mac / Windows).
The “Plex Dash” app is on optional extension to that
