How leaving soon is calculated
TMDB does not publish an expiry feed. CineKeep does not invent leaving dates. The Shelf is your bookmarks for this country; Where to watch still uses TMDB providers.
Keep list warnings
When you open a saved title, CineKeep refreshes TMDB watch providers so a show that moved services in your country updates on the Shelf.
Not a reminder to pirate
CineKeep will not point you at unofficial streams. Use Find on the listed service, or skip it.
