Screenwise Meter, launched in 2012, had a similar installation process to Facebook research applications that were now closed. She urged users at the age of 18 and older (or 13 years in a family group) to install the app and a business credibility certificate to track user activity on their mobile devices.
The company now apologized and closed the iOS app:
IOS for Screenwise Meter should not work under Apple's development program – it's a mistake, and we're sorry. We have disabled this app on iOS devices. This application is completely voluntary and has always been. We have been notified to users in advance of how we use their data in this application, we do not have access to encrypted data in apps and devices, and users can unsubscribe at any time.
While Google was much more honest and provided all the information on how it collected data, it undoubtedly violated Apple's corporate certificate rules and collected user data. Companies that rely heavily on user data to run their businesses need to re-evaluate old applications and services they initiated when data protection rules were not as strict as they are today – and to avoid using them in the future.
