What works without a connection?
Previously opened public calculator pages can work offline after the app has prepared its cache. Sign-in, account favorites, saved portfolios, goals, and admin changes need an internet connection. Account information is not stored in the offline cache.
Installation depends on your browser. The hosted website needs HTTPS; installation does not work from an unzipped HTML file.
