You will be able to view your analytics data and download your short link information in csv format for up to one year, until March 30, 2019, when we will discontinue goo.gl.

Dynamic Links are smart URLs that allow you to send existing and potential users to any location within your iOS or Android app. They survive the app install process, so even new users see the content they're looking for when they open the app for the first time. Dynamic Links are free forever, for any scale.
