Voyager is built using capacitor and ionic framework, which is a web framework to build mobile apps, basically. It doesn’t “use elements from chrome”, it uses progressive web apps (PWAs), which you can set up with whatever browser you choose. They’re basically web apps that you install to your phone’s desktop.

Additionally, there’s currently an app in TestFlight to install it on iOS natively and will probably soon be a version for Android. It’s still a web app wrapped in a native wrapper, but it unlocks native functionality and feels much nicer.

Anyway, all of this to say, nothing about the way the app was built inherently includes anything from chrome. Only if you use chrome to make it a PWA.

It’s a webapp so you run it in your browser - it only uses chrome if you choose to use chrome.

I’m using it in Firefox on Android, but you could also use it in Safari on iOS for example.
