What does Mirror Contacts mean?

Mirroring your contacts helps you unlock the full power of your network on Lumina. With your permission, Lumina securely transforms your contacts’ phone numbers into encrypted codes directly on your device, so the original numbers never leave your phone. These encrypted codes are then used to find mutual connections on the platform for you (and only you) to access. The process is private and secure. Even we can’t see the original numbers! You can enable/disable contact mirroring anytime in Settings.
