When Apple introduced its App Tracking Transparency system in 2020, Facebook (now Meta) took a hard line against it, claiming it would hurt the world’s largest social media platforms and small businesses that rely on tracking data to make money.
That means that if you open a website in the Facebook or Instagram apps on your iPhone, Meta can track your activity across the web and potentially even on other Meta apps. The tracking code could even collect sensitive information like passwords, payment information, and screenshots.
Meta claims these tracking codes follow the tracking preferences of iOS users. A company spokesperson told The Guardian, “We intentionally developed this code to honour people’s choices on our platforms.”
