Apple will allow your subscription apps to charge you more money without your permission
Apple has changed its App Store policies to allow subscriptions to auto-renew without your explicit approval, even if the developer has increased the monthly or annual fee. Prior to the rule change, customers had to manually opt-in to a subscription renewal if it came with a price increase; now, that isn’t always the case, but you will still be warned about the price change before it occurs. Apple says it’s making the adjustment to help consumers avoid accidentally losing access to a subscription because they missed an opt-in notification.
According to Apple’s Monday evening tweet, developers must adhere to certain rules in order to offer what the company refers app as “an auto-renewable subscription pricing increase.” For starters, it can only be so much – according to Apple’s guidelines, if a developer raises a weekly or monthly membership price by more than 50% and the difference is more than $5, it does not qualify. Devs can still raise the price of a yearly membership by 50%, but not more than $50 USD without requiring an opt-in.
