Privacy oriented rss feed that I can put my own links and turn them into a rss feed

Hello. I'm not looking for something too feature rich, I don't mind if it has a lot features but not looking for them right now.

I want to be able to copy a link and paste it into an app then be able to read is as a rss feed. If the app has a feature to categorize rss feeds I could enjoy it a bit but if not then that's ok.
