Update: We're being told by one developer that actually this wording is unchanged, and the 15-minute window still applies, it's just that Google has that long to refund the money. We're seeking clarification from Google, and watching our hope wane.
Google caused a fairly big stink nearly a year ago when it changed the window to uninstall and refund a purchased application to just 15 minutes -- a far cry shorter than 24-hour window we'd previously enjoyed.
But according to a new version of the developer distribution agreement being pushed out today, that window has been expanded, and expanded to a full two days. Here's the line from Section 3.4:
Products that cannot be previewed by the buyer (such as applications): You authorize Google to give the buyer a full refund of the Product price if the buyer requests the refund within 48 hours after purchase.
Good on Google for changing this one. While we don't want anyone abusing the refunds process, 15 minutes was absolutely too short a time to try out an application.
By the way, if you're a developer, make sure you log in to your developer portal to accept the new agreement. Wouldn't want your app yanked unnecessarily.
Thanks, Joe and Nick!
