Key facts

- Loupe is an iOS and iPadOS app that gives you a hands-on tour of the device fingerprinting surface

Summary
Trackers don't need your name, email, or location to recognize you online. Loupe groups every reading into three tiers, reflecting the cost of access:. Passive, visible to any app with no prompt at all (locale, time zone, screen, battery, and more). Needs Permission, readings that trigger an iOS prompt (contacts, photos, location, calendars).
