Limit Ad Tracking (LAT) is a feature in Apple iOS that allows users to opt-out of personalized advertising. Personalized advertising, also known as interest-based advertising, uses information about a user's online behavior to show them ads that are more relevant to their interests.
When Limit Ad Tracking is enabled, iOS devices will no longer send information about a user's activities to advertisers, which will reduce the amount of personalized ads they see. However, it's worth noting that users may still see ads, but they will be less relevant and may be based on broader factors such as their geographic location or the type of app they're using.
It's important for users to understand that Limit Ad Tracking does not stop all forms of advertising, but it does give users more control over their privacy and the data that's being shared with advertisers.
