Save choices as you browse
Choose Save title on a movie or series page. My List keeps that choice in this browser, and the same control removes it when your plans change. On a series, a checkpoint records the last episode you completed. It is a reminder you set yourself, not an automatic record of what a player has watched.
Create a copy before moving
Open My List and choose Create backup. Copy the complete text from the backup field and keep it somewhere you can find again. The backup contains selected title identifiers and checkpoints. It is not a movie file and does not include another service’s account or playback state.
Restore by merging
In the destination browser, open My List, paste the backup into Restore backup and choose Merge backup. Existing title selections remain, duplicate selections are avoided and existing checkpoints are kept when they conflict. Read the result message instead of assuming a partial text paste succeeded.
Why a list can disappear
Private browsing, a different browser profile or clearing site data can leave you looking at a new list. Before clearing anything, create a backup if the old list still opens. Search and catalog browsing do not require you to keep a watchlist, so you can use the site without saving choices.
