I own a fire stick and I'm considering selling it and buying an hdmi cable in order to connect my PC to the TV.

But before doing that I'm curious, if I were to install KODI on the FireStick TV, where does the app/device actually store my pirate videos such as TV series, anime etc.?

Also, if you do know how to use closed captions I'd really appreciate it because a big reason of me using netflix on fire stick and paying for the service were subtitles to improve my English.

I just realized chrome can do that on any video, that's why I'm really considering to just connect my personal computer to my television and stream pirated content from any platform.
