🔒 Privacy Policy

Quiz Vault – Create. Practice. Excel.

Last updated: February 19, 2026
This Privacy Policy explains how Quiz Vault (com.myquiztrn.app), a free Android quiz practice app, handles your information. Quiz Vault lets you create your own quizzes, organise them by subject, and practice daily. By using the app, you agree to this policy.

📋 1. Information We Collect

Quiz Vault is designed to work entirely offline. We do not collect, store, or transmit any personally identifiable information (PII) to our servers.

No account or registration required.
No name, email, or phone number collected.
✅ All your quiz data stays exclusively on your device.
  • Quiz questions, answers, explanations, and subjects you create are stored locally on your device using Hive database.
  • Your practice statistics (day streak, accuracy, results) are stored locally only.
  • No data is ever sent to any server or third party by us.

📢 2. Advertising – Google AdMob

Quiz Vault is a free app supported by advertisements provided by Google AdMob. As required by Google Play policy, we fully disclose AdMob's data practices below.

Google AdMob may collect:
• Advertising ID (GAID) of your device
• IP address and general location
• App interaction and usage data

This data is used by Google to serve relevant, personalised advertisements. It is governed by Google's Privacy Policy and AdMob's data safety practices.

How to opt out of personalised ads:

  • Go to your device Settings → Google → Ads
  • Enable "Opt out of Ads Personalisation"

Opting out does not remove ads — you will still see ads, but they will not be personalised.

📁 3. Storage Permission

The app requests storage access only for these two features:

  • Export: Saving a backup file (.json) of your quizzes to your chosen device storage location.
  • Import: Reading a backup file you explicitly select to restore your quizzes.

We never read, scan, or upload any other files from your device. All file operations are user-initiated only.

🌐 4. Internet Permission

The INTERNET permission is used solely to load advertisements via Google AdMob. Quiz Vault does not communicate with any backend server. All your quiz data remains completely offline.

🤝 5. Data Sharing

We do not sell, rent, or share your personal data with any third parties, except as described in Section 2 (Google AdMob advertising). Your quiz content belongs entirely to you.

👶 6. Children's Privacy

Quiz Vault does not knowingly collect personal information from children under the age of 13. No account, name, email, or other personal detail is required to use the app. The app is suitable for all ages.

If you are a parent and believe your child has provided personal information to us, please contact us immediately so we can address it.

🛡️ 7. Data Security

All your quiz data is stored locally on your device, protected by your device's built-in security. Exported backup files are base64-encoded. We recommend keeping your device secured with a lock screen to protect your local data.

🔄 8. Changes to This Policy

We may update this Privacy Policy as the app evolves. Any changes will be reflected on this page with an updated date at the top. Continued use of Quiz Vault after changes constitutes your acceptance of the revised policy.
