A class-action lawsuit has been filed against Google on behalf of parents in the United States who have seen their credit cards charged by the Play Store after their children inadvertently purchased virtual currency or content while playing free or extremely low-cost games on smartphones and tablets. The complaint is that Google promoted free games and allowed these expensive purchases with the lax restrictions it places on in-app purchases.
Specifically, the complaint describes how children are asked to buy virtual currency to continue playing, even worth 100 real dollars. Google allows registered users of the Play Store to make app and in-app purchases after entering a code. However, as stated in the complaint, Google stipulates that once the code is entered, there is a 30-minute window for free use without having to type it again. During this “window,” in-app purchases can charge the guardian’s credit card by up to 100 dollars.
The lawsuit Imber-Gluck v. Google Inc was filed by the law firms Berger & Montague, PC, Del Sole Cavanaugh Stroyd LLC, Carpenter Law Group, and Patterson Law Group, APC in the United States District Court for the Northern District of California.
Apple has been ordered to refund $32.5 million to millions of App Store customers, the iPhone and iPad app store. This was after it was determined that the purchases were made through in-app games by their children, without the informed consent of the (inflated) account holders. The case concerns in-app purchases made before 2011, when Apple changed its policy that allowed unlimited charging of the linked credit card within 15 minutes of entering a relevant code.
To keep control over in-app purchases and games on tablets and smartphones, Apple and Google have adopted a similar tactic. The user must set their system to require a password before their credit card is charged. What differs is how often a password will be requested for so-called in-app purchases and who is responsible for unintended purchases.
"Offers in-app purchases": Finally, note that the Play Store has added the ability to see if the app has in-app purchases, that is, if the child will be asked to make purchases within the application.
