Network and Distributed System Security (NDSS) Symposium 2025 · Day 2 · LLM Privacy and Usable Privacy
In an era of increasing data collection and privacy concerns, transparency has emerged as a critical tool for empowering users. Apple's introduction of the **App Privacy Report (APR)** in iOS 15 marked a significant stride in this direction, offering iPhone users an unprecedented, device-wide overview of how their applications and visited websites interact with their data and network. This talk, delivered by Xiaoyuan Wu from Carnegie Mellon University, delves into a comprehensive study evaluating the effectiveness of the APR, specifically focusing on users' comprehension, reactions, and intentions to act based on the information presented.

Competent usability research on Apple's App Privacy Report — well-structured study, honest findings, and the recommendations are reasonable. But this is a privacy HCI paper at a security conference, and the ceiling is low: it confirms what anyone who's looked at APR already suspects, without producing insight that materially changes how defenders or platform engineers operate.
