How leaving soon is calculated
Movie of the Night reports expiring catalog changes for the country CineKeep detected (or the one you set). The app sorts by soonest date when MotN provides one. TMDB supplies the poster and score so you can decide whether it is worth a last watch.
Keep list warnings
If a title you saved is expiring on a service you use, CineKeep can badge it. If it left Netflix but MotN still finds it on Max in the same country, Where to watch updates — the guide follows the catalog, not a frozen screenshot.
Not a reminder to pirate
Leaving soon means the official license is ending. CineKeep will not point you at unofficial streams. Watch on the listed service, or skip it.
