How iCloud sync works
Nexus Contacts uses your iCloud account to sync data across your devices. Your contacts, notes, reminders, and selfie photos are stored in your personal iCloud — never on Common Nexus servers.
Make sure iCloud is enabled for Nexus Contacts in your device's Settings > [Your Name] > iCloud > Apps Using iCloud.
Using Nexus Contacts on multiple devices
Install Nexus Contacts on any iPhone or iPad signed into the same iCloud account. Your data syncs automatically — including selfie photos, context notes, reminders, and ShareCards.
Changes made on one device appear on all others within minutes.
