iOS : Apple limits monitoring advertising

Monitoring iOS devices is now reserved for the display of advertising.

In the settings of iOS devices under the "Privacy" tab, it is possible to activate a limited advertising follow-up. In other words, iOS devices feature a unique identifier called UDFA (Identifier for Advertisers), which allows to better target advertising. When the limited tracking is enabled, applications can not use the identifier to target advertising. The reset option resets the settings to zero.

Now, Apple no longer allows developers to use the UDFA when the application does not display advertising. Some developers have seen their applications and even some updates rejected by Apple validation teams for this reason. Indeed, some services such as Mixpanel used the UDFA for tracking statistics. Now it has to use other services to gather statistics on the use of applications. Apple has probably tightened a little the screw to protect its users, unless it is simply to prevent the competitors like PayPal or Stripe which, depending on Tech Crunch, would use UDFA for transactions.
