Source Code Nutrition Label

You shouldn’t have to worry Replies for Hacker News is using some privacy-sucking third-party library. Apps shouldn't be mystery meat. You should know what code goes into them.

Generally speaking, there are two kinds of third-party code used by apps: those used inside the app, and those used to build the app.

Code used in the app is included with Replies and will run on your device. For example, if an app shows ads from Facebook, it might include the Facebook SDK (Replies does neither).

Then there’s code used to build the app, which is not included with Replies. It only runs on my computer when I make a new version of the app. I can’t list every piece of software that goes into building Replies ("macOS"), but I can tell you what third-party code directly helps build the app.
