According to a new report from Forbes, Apple has started rejecting app updates that do not comply with the company’s App Tracking Transparency guidelines that the company has implemented as of iOS 14.5.
“Our app was rejected by Apple’s app reviewer and accused the MMP SDK of creating fingerprint ID,” says Aude Boscher, product manager for French transportation company Heetch, on a Slack channel. “I’ve seen other people complaining … so it could happen to you soon too!” said.
The message that Apple sends to companies that collect other important data of users, especially fingerprint data, with third-party SDKs is as follows:
“Your application uses algorithmically transformed device and usage data to create a unique identifier to track the user. Device information collected by your application may include some of the following: NSLocaleAlternateQuotationBeginDelimiterKey, NSTimeZone, NSLocaleGroupingSeparator, NSLocaleDecimalSeparator …”
Applications using the Adjust software kit are affected
According to mobile marketing analyst Eric Seufert, the problem is caused by a software development kit from Adjust, a mobile measurement company. In this case, Apple’s new rule will affect thousands of applications. Because Adjust states that the software kit on its website is used by “more than 50,000 applications” and according to AppFigures, 18% of the applications in the App Store and 11% of the applications in Google Play use Adjust. Adjust has now updated its SDK to remove the code that accesses information such as CPU type, phone memory, battery status, and state of charge so that Adjust’s previously rejected apps can now be reassessed if they use the updated SDK.
Apple has not yet announced when it will release iOS 14.5. However, six betas have been released so far, and the software is scheduled for release in the spring.
