Loupe
A privacy-focused iOS app that raises awareness about what native apps
...Rather than collecting or transmitting personal data, Loupe focuses on education and awareness by demonstrating how device characteristics can be observed through standard system interfaces. It provides a hands-on exploration of identifiers, hardware information, and other attributes that can contribute to fingerprinting techniques. All information remains on the device unless the user explicitly chooses to export it, reinforcing the project's privacy-first philosophy. By exposing these signals in a clear and accessible way, Loupe helps users, developers, and researchers better understand the privacy implications of mobile device fingerprinting.
