Record a completed episode
Open a series, choose the season and enter the last episode you finished. Save the checkpoint. The form limits the episode number to the recorded range for that season. It does not import progress from an external player.
Resume with context
Check the title, year, season and episode together. Specials and split seasons can be organised differently by viewing services. Compare descriptions carefully without reading ahead into spoilers.
Clear or keep it
Clear the checkpoint when starting over. The title bookmark in My List is separate, so removing one does not require removing the other. Both are local to this browser. Another device or a private window can have a different list.
