So as long as you access the application once a week, you're safe. Or, alternatively: > As mentioned, the seven-day cap on script-writable storage is gated on “after seven days of Safari use without user interaction on the site.” That is the case in Safari. Web applications added to the home screen are not part of Safari and thus have their own counter of days of use. Their days of use will match actual use of the web application which resets the timer. We do not expect the first-party in such a web application to have its website data deleted. Still, horrible idea and horrible implementation, but I think it's known by know that Apple/Safari will always be hostile towards web apps as it cuts into their own App Store revenue.
