Privacy Policy

1. Introduction

This Privacy Policy explains how QuizHub.dev ("we," "us") collects, uses, and shares information when you use our website and services. It should be read together with our Terms of Service.

2. Information we collect

Account information: When you register, we may collect your name, email address, password (stored as a secure hash for email accounts), and authentication type. If you use Google Sign-In, we receive information Google provides (such as email, display name, and Google account identifier) according to your Google account settings.

User content: Quizzes you create, responses, comments, discussions, ratings, and related metadata.

Usage information: Quiz attempts, study progress, timestamps, IP address, browser type, and pages visited, collected through normal server logs and application functionality.

Cookies and similar technologies: We use session cookies for login and security, and may use persistent cookies for "remember me" functionality. You can control cookies through your browser settings.

3. How we use information

We use information to:

• provide, maintain, and improve the Service;
• authenticate users and secure accounts;
• display quizzes, comments, and community features;
• communicate with you (e.g., email verification);
• enforce our Terms and protect users and the Service;
• comply with legal obligations; and
• analyze aggregate usage to improve the product.

4. How we share information

We do not sell your personal information. We may share information:

• Publicly on the Service: Your display name and User Content you choose to publish (quizzes, comments) may be visible to other users and the general public depending on sharing settings. If you enable it in Account settings, your display name may appear in the site's recent activity feed when you complete a quiz or flashcard session; you may turn this off at any time.
• Service providers: Hosting, email, or infrastructure providers who process data on our behalf under confidentiality obligations.
• Legal requirements: When required by law, subpoena, or to protect rights, safety, and security.
• Business transfers: In connection with a merger, acquisition, or sale of assets, subject to this Policy.

5. Data retention

We retain information as long as your account is active or as needed to provide the Service. We may retain certain data after account deletion for backup, legal compliance, fraud prevention, or dispute resolution, then delete or anonymize it in the ordinary course.

6. Security

We use reasonable administrative, technical, and organizational measures to protect information. No method of transmission or storage is 100% secure; we cannot guarantee absolute security.

7. Children's privacy

The Service is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, contact us and we will delete it.

8. International users

If you access the Service from outside the United States, you understand that information may be processed and stored in the United States or other countries where our providers operate, which may have different data protection laws.

9. Your choices and rights

Depending on your location, you may have rights to access, correct, delete, or port your personal data, or to object to certain processing. Contact us to make a request. We may verify your identity before responding.

10. Third-party links and sign-in

The Service may link to third-party sites or use Google Sign-In. Their privacy practices are governed by their own policies, not this one.

11. Changes

We may update this Privacy Policy. The effective date at the top will change when we do. Continued use after changes constitutes acceptance.
