I know that there is a problem with creating subtitle files containing the original phrases (or even the translation of what has been said) and to release them.


There are platforms, eg. OpenSubtitles, where you can download all these subtitle files. Even though the providing of these subtitles is not legal, I would like to get only the words and their count in the movie.


If an developer sells an app, that uses a subtitle API, to retrieve the subtitle files for creating word-statistics about the movie, would this be a legal problem to any person involved?


* Is the developer breaking the law, because his app downloads the whole subtitle file temporarily to the users device?
* Is the user of the app breaking the law, because the app downloads the whole subtitle file temporarily to his device?
* Are the resulting statistics (words and their count) in anyway copyrighted?



Usage of subtitle files of copyrighted movies to get statistics about used words and their number count
