Loupe – A iOS app that raises awareness about what native apps can see
Summary
Loupe is an open-source iOS/iPadOS app that reveals what native apps can see by reading public iOS APIs and showing raw readings. It categorizes signals into Passive, Needs Permission, and Advanced to illustrate device fingerprinting risks, demonstrating how apps can recognize a user without personal data. The project highlights privacy awareness and notes AI-assisted coding involvement in its construction.
