Since the last iOS update, which requires apps to ask for permission to be able to “track” the data of their users, only a tiny minority of these agree to have their activity followed. Depending on the day, this proportion varies only slightly from 11 to 13%, all the other users categorically refuse that their data be shared.
It is therefore clear that when asked for their opinion, app users refuse en masse to have their personal data analysed for advertising purposes. The phenomenon is even more widespread in the United States, where in the first two weeks of iOS 14.5 operation, the acceptance rate for being tracked never exceeds 5%, according to Flurry statistics.
