Facebook User Data

Last updated: June 2026

This section explains how Zirzoner handles data from your Facebook account when you choose to sign in with Facebook.

How Facebook Sign-In Works

Facebook Sign-In is an optional authentication method. Instead of creating a new username and password, you can use your existing Facebook account to sign in to Zirzoner.

When you click "Sign in with Facebook," Facebook asks you to confirm what information you want to share with us. You control this through Facebook's consent screen.

We request only the minimum data needed to create and manage your account.
