Google has announced new changes to bolster privacy protections for Android users. In an email sent to app developers of the Play Store, the company has detailed how access to a user's Advertising ID would be restricted once a user opts out of receiving personalized ads. Advertising ID is a device identifier that allows marketers to track users as they switch between different apps.
On sending a request, the Android system would respond back with a string of zero's instead of an actual Advertising ID that can be used to track the user. The change means Android users can now opt out of interest-based advertising. The company has also updated its
support page for Advertising ID detailing the change.
