Your saved choices
My List, series checkpoints and viewing-country preferences are stored in the browser where you use them. They are not automatically shared with another browser. Clearing site storage removes those local choices. Create a list backup beforehand if you want to keep them.
Search and artwork
Search terms appear in the search page address, so they can remain in browser history. Movie artwork is loaded from TMDB's image service, which receives the network information needed to deliver those images. The catalogue does not require an account for these browsing functions.
When you open a viewing link
Watch now sends the selected title or opens a matching title page on JustWatch for the chosen country. That website and the service you subsequently select have their own privacy terms, cookies and account features. They do not use this catalogue's local checkpoint as automatic playback history.
Manage local data
Remove a saved title from its detail page or clear a checkpoint using the series form. You can remove all local preferences through the browser's site-storage settings. Check any backup text you keep in another note or document separately, because clearing the browser does not erase that copy.
