My daughter has been using this app (and previously the 1st grade app) for while. We really loved it because the app used to generate random questions related to multiple topics. That way she would get a fairly balanced set of easy questions mixed with hard questions. Another thing that I liked a lot about this app is that it did not ask you to sign up or create a profile that would be connected to the internet. Therefore, all the data was contained within my device.
The new update that was pushed to my iPad today is not a cosmetic change on the application. It is a structural change. The new app is tailor to gather data about those who use it. Parents/teachers must create a profile that is connected to the internet. Children do not get randomized sets anymore (at least not on my iPad) unless it is my understanding that a internet connected profile is created.
This update should never have come out without a privacy notice in advance of the update. I can read the privacy notice now but I cannot do anything about it because it is only possible to read it after the update. I cannot go back to the old app unless I recover the iPad from a backup, which obviously makes no sense.
Beware, this is not an update. This is an downgrade. Both apps on the app store should coexist even if the old one is not updated anymore. I guess StudyPad, Inc. did not want to loose the revenue stream by requesting current and prospective users to buy the new app. They also do not want to miss the revenue stream that comes from farming customer data.
The way this update has been handled is outrageous!!
