Choices kept in this browser
Cinebloom uses browser storage for My List, episode checkpoints and your viewing country. These features do not require a Cinebloom account. The information stays with that browser unless you copy it using the backup tool. Removing site storage removes the saved choices.
Images and viewing destinations
Movie artwork can load from TMDB image servers. Watch now opens JustWatch, and a viewing option can take you to another service. Those destinations receive the requests involved in opening their pages and operate under their own privacy policies.
Backups are yours to manage
A copied list can reveal the movies and series you saved. Store the text somewhere appropriate for that information and share it only when you intend to. The backup does not need personal identifiers or service-account credentials.
Using a shared device
Another person using the same browser can see its saved list and checkpoints. If you want to remove those choices, remove the saved titles or clear this site's storage after preserving anything you want to keep. A private browsing session may discard storage when the session ends.
