Yeah, I will write it down on the website. As I mentioned below (https://news.ycombinator.com/item?id=28700703), I do not store the URLs that you go to (though of course you have to trust me on that), and as all the processing is done on the server, that URL doesn't get sent to any external APIs (though if I go through with adding reddit I might need to send it to the reddit API).
I do collect some telemetry statistics (right now the number of times you have seen the sidebar + the number of times you clicked/scrolled/closed it), aggregated hourly.
