Read this site offline

Off by default. Turning it on saves the reference onto this device, in this browser, so it keeps working on a plane, in a basement, or on a train through a tunnel.

How it behaves

With a connection, pages come from the network exactly as before, so a saved copy never shows stale text to a reader who could have had the current build. The saved copy is the fallback, used only when the network is not there.

Each deploy replaces the whole saved copy rather than mixing two builds. Open the site once while connected after an update and the new version is picked up.

On an iPhone or iPad

iOS gives a home-screen web app its own separate storage. Turning this on in Safari does not carry over to the icon on the home screen. If this site is added to the home screen, open it from that icon, come back to this page, and turn it on again there while connected.

iOS also clears an unused site’s saved data after about a week. Opening the site while connected refills it.
