This page covers this website only. For the Android app's own open-source dependencies — every library it ships, with its license — open the app itself: Settings → About → Open source licenses. That list is generated fresh from each dependency's own package metadata every time the app is built, so it can't go stale the way a hand-written page here would.
01Fonts
This site doesn't bundle any font files of its own — every typeface loads on request from Google Fonts, under the SIL Open Font License 1.1.
02Services, not code
Together also relies on Google Firebase (hosting, auth, database, storage, functions, messaging) and OpenStreetMap's public tile servers for map images. Neither ships any code in this site or the app — see the Privacy Policy for what each one actually sees.
