(IDFA) Identifier for Advertisers

The Identifier for Advertisers (IDFA) is a unique identifier on Apple devices, such as iPhones and iPads, that allows advertisers to track a user's activity across different apps. The IDFA helps advertisers to provide personalized advertising experiences, target specific audiences, and measure the success of their ad campaigns.

However, with the growing concern over online privacy and data protection, Apple has recently implemented changes that require apps to ask for explicit user consent before tracking their IDFA. This means that users can choose to limit the tracking of their activity, giving them more control over their personal data.
