4. Privacy Architecture and Unlinkability Guarantees

4.1 Overview

Loxation is designed around a foundational principle:

Users must be discoverable only in the moment, without creating lasting digital traces in the physical world.

This section describes how Loxation achieves strong, cryptographically enforced privacy and unlinkability while still providing authenticated device identity, secure transport, and trustworthy group membership. Loxation accomplishes this through a strict separation of identities, ephemeral cryptographic primitives at the BLE layer, and authenticated session establishment using App Attest, Play Integrity, and MLS.

We would like to announce the early releases of the loxation app for both the IOS App Store, and Google Play Store
