This comment is irrelevant to the topic at hand. Not only is this app (or any other torrent streaming app, including uTorrent and qBittorrent and PopcornTime) not have any DRM, you can use the fully downloaded file after you stream it. [1]

For non-torrent sources, streaming is not tied to DRM either. Most youtube videos are not flash based, but streamed MP4 files that aren't DRM'd in any way; you can get the MP4 file if you want. Service disruption is a problem, but there is always a trade off- and honestly, I'm more likely to lose a hard drive full of video files than Youtube is likely to disappear in the next 10 years.
