FIRST VERSION / 4 OCTOBER 2026

Your learning.
Your data.

QuizMasterPro stores your libraries, facts, review ratings and review times to schedule your personal practice. Account data is associated with your Firebase user ID. Authentication is handled by Firebase and the identity provider you choose.

The demo

Demo libraries and reviews stay in this browser’s local storage. They are not synced to an account. You can clear them using Reset demo in the app. Clearing browser data also removes them.

Account data

Signed-in data is stored on the Commodo application server. Your sign-in token is sent to the server over HTTPS to verify access. Other accounts cannot read your libraries through the app. You can export your libraries as JSON and delete individual libraries and facts in the app. Export files contain your learning data; keep them private.

TEST availability

This is an initial testing version. Please use sample learning material rather than sensitive personal information. Account sign-in is available only after the separate Firebase project and providers are configured. The first version has no advertising or analytics scripts.

Before public launch

Data retention, account deletion, support contact and hosting details will be published before a production launch. This page describes the initial version; it is not a complete production privacy policy.
