Google OAuth & Sign-In Integration Purpose:

To streamline registration and profile management, the Calistry application implements Google Sign-In via Google OAuth. Users can choose to sign in with their Google account to securely register a Calistry customer account. This integration is used exclusively to authenticate users, allowing them to safely save shipping details, view order histories, submit product reviews, and complete purchases more quickly. No third-party data is shared, and we only access basic identity details (email, name, and profile picture) to verify and service your account.
