If you're the parent of a minor child that unknowingly made in-app purchases on an iOS device under Apple's old purchase rules, listen up. Apple on Monday announced details of a settlement related to a class action lawsuit covering this issue which is believed to encompass some 23 million people.

Parents may choose between a single $5 iTunes Store credit or a credit equal to the total amount of Game Currency that a minor charged to an iTunes account without the owner's knowledge or permission. Apple notes that a cash refund will be given if you no longer have an active iTunes account or if your claims exceed $30 in total.

Participants have until January 13, 2014 to submit a claim online or via snail mail. Furthermore, class action members have until August 30, 2013 to either exclude themselves from the settlement while reserving the right to be part of other lawsuits against Apple about the claims and allegations in this case or object to the ruling.

If you wish to speak your mind, you can ask to speak in court about the fairness of the settlement no later than September 27, 2013. If you simply do nothing, you'll give up your rights and receive no payment under the settlement.

Apple points out that the settlement isn't an admission of any wrongdoing. The legal notice notes they deny all allegations and are entering into the settlement to avoid burdensome and costly litigation.
