An API for enabling web applications on the lock screen of a device. The API would provide a way for web applications to indicate they can be run on the lock screen, pass data from the lock screen instance of the app to the unlocked instance (and vice versa), and be notified when there is data available.


This is needed for enabling web apps on the lock screen of a device. This would allow users to use web apps for tasks such as checking a calendar, using a calculator, taking a photo, or taking a note, all without going through the extra step to unlock their device first. Such an API would be applicable to both desktop and mobile platforms, though it will require some operating system support to implement it.
