Choices saved on this device
The website stores saved title identifiers, episode checkpoints, viewing country and recently opened title pages in browser storage. These records support the features you use; they do not create a cloud account or automatically follow you to another device.
Your controls
Remove a title with its heart, clear a checkpoint on the series page and clear recent history from Recently browsed. Those controls affect separate records. A copied backup remains wherever you saved its text.
External requests
Posters and backdrops are loaded from TMDB image servers. Opening Watch now contacts JustWatch. Those services receive the requests needed to display their content, and their own privacy practices apply there.
Before clearing site data
Export a backup if you want to retain your list. Clearing browser storage can remove local choices, but it does not alter an outside subscription or delete a backup stored elsewhere.
