Export all starred posts in CSV or XML

I've used the app for many years and I've starred too many posts for history chronology and, in order to avoid to loose them (because there's no method to sync with Google Account, for example) it would be better if I could integrate a button in the settings that allows me to export a CSV or XML file and choose what fields I want to export (title of the post, content, posted_date, URL and so on...)

It would be possible?
