OfflinePuffin I also want to ask dose Vanadium sandbox web apps like normal webpages or dose it give them more permissions or features on launch.
The only real difference between a web app and a normal website on Vanadium, is that the web app does not open in a new tab in your browser, but as a separate window. Apart from that, they are essentially the same thing.
Both web apps and websites benefit from the additional sandboxing present in Vanadium, when compared to a native app.
When you use a web app, site data and cookies get saved in Vanadium, which you can manage in Vanadium settings, just like for any other website. Note that if you remove the web app from your home screen it does not delete cookies or site data from that web app. You would need to go back and do that in the Vanadium app, should you wish to.
A web app can also request certain permissions if it likes, but then so can a normal website.
