Google very likely only scans the input application, I'm not sure why you would bother with an automated system to detect a code repo for it when the majority of applications on the Play Store are closed-source and there's a low confidence if the builds are not repeatable. Anyway, regardless of that it sounds like it would be easily defeated with the following C format string: "%s-%s: %s/%s (%s) %s/%s %s/%s" with argument list: "User", "Agent", "Mozilla", "5.0", "X11; Ubuntu; Linux x86_64", "Gecko", "2010000", "Firefox", "90.0" For bonus points you can make those floating points, too, and split it up a bit further. Now nobody can scan for this without a lot of false positives (The strings are going to display in anything that embeds a web browser or references it, lol) and you get ultimate flexibility.
