🔒 Privacy Policy

Welcome to QuizCheckpoint.com (“QuizCheckpoint,” “we,” “our,” or “us”).

This Privacy Policy explains how we collect, use, and protect your information when you use our website and related services (collectively, the “Service”).

By using QuizCheckpoint, you agree to this Privacy Policy. If you do not agree, please do not use the Service.

1. Information We Collect

a. Information You Provide

When you sign in with Google, we receive your basic Google account information, which includes:

• Your name
• Your email address
• Your Google profile picture (if available)

This information is provided through Google OAuth 2.0 for authentication purposes only.

We do not access, store, or use any other Google data such as your Gmail, Drive, Calendar, Contacts, or other Google services.

✉️ Email Sign-In (Magic Link)

In addition to Google Sign-In, QuizCheckpoint allows users to create an account or log in using their email address. When you choose this option, we send a one-time “magic link” to your email to verify your identity and complete the login process.

Your email address is used only for:

• Authentication and account access
• Transactional messages (e.g., login links, quiz notifications, or account updates)

We do not use these email addresses for marketing or share them with third parties.

b. Information You Create in QuizCheckpoint

We may store limited data you create inside QuizCheckpoint, such as:

• Quiz titles, questions, and answers
• Email addresses you enter to send quizzes to
• Basic usage logs (e.g., timestamps for quiz creation or completion)

This information is stored securely in our database to operate the Service.

c. Automatically Collected Information

We may collect non-personal data such as browser type, device information, and usage analytics (via tools like Google Analytics or Vercel logs) to improve the app’s performance.

2. How We Use Information

We use collected information solely to:

• Authenticate users via Google Sign-In
• Operate and improve our Service
• Communicate with users regarding their account or quizzes
• Ensure the security and proper functioning of the platform

We do not sell, rent, or share personal data with third parties for advertising or marketing purposes.

3. Data Storage and Security

Your account information and quiz data are stored securely using Supabase (a trusted cloud database service). We take appropriate technical and organizational measures to protect your data against unauthorized access, alteration, disclosure, or destruction.

4. Google User Data Policy Compliance

• QuizCheckpoint’s use of information received from Google APIs complies with the Google API Services User Data Policy, including the Limited Use requirements.
• We only use Google data to authenticate users.
• We do not transfer Google user data to any third party.
• We do not use Google data for advertising or marketing purposes.
• We do not store Google tokens or credentials beyond what is necessary for sign-in.

5. Data Retention and Deletion

You may request deletion of your account and all associated data at any time by contacting support@quizcheckpoint.com.

We will permanently delete your information from our systems within a reasonable period, typically within 30 days.

6. Cookies

QuizCheckpoint uses cookies or local storage only for essential functionality such as maintaining your login session. We do not use tracking cookies for targeted advertising.

7. Children’s Privacy

QuizCheckpoint is not directed toward children under the age of 13. If you are under 13, please do not use the Service or submit any personal information.

8. Third-Party Services

QuizCheckpoint may use trusted third-party services for hosting and analytics, such as:

• Vercel (web hosting and deployment)
• Supabase (database and authentication)
• Google OAuth (sign-in service)

Each third-party service has its own privacy policy, which governs their data handling practices.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last Updated” date. Continued use of the Service after such updates means you accept the revised policy.
