GitHub – Mysk-Research/loupe: a Privacy-Focused iOS App That Raises Awareness About What Native Apps Can See
Loupe is a privacy-focused iOS and iPadOS app that reveals the types of device information accessible to native apps through public iOS APIs, demonstrating how this data collectively creates a device fingerprint for tracking. It categorizes data access into passive (no prompt), permission-based, and advanced side-channel signals, showing users exactly what their device exposes without sending any data off-device. The app is open source, built mainly using AI coding tools, and aims to raise awareness about app tracking practices on Apple devices.
