This Privacy Policy explains how IQ Test Practice: Raven Matrices collects, uses, stores, and protects information when you use our mobile application and related services.
1. Information We Collect
We may collect and store the following information:
- Authentication information, such as your user account identifier provided by Clerk.
- Email address, if you use email-based authentication through Clerk.
- Username or display name.
- Avatar or profile image.
- Scores, leaderboard data, gameplay progress, or similar app activity.
- Technical information necessary to operate, secure, and maintain the app.
2. Authentication Provider
We use Clerk to provide authentication and account management. Clerk may process authentication-related information according to its own privacy policy and security practices.
3. How We Use Information
We use collected information to:
- Create and manage user accounts.
- Allow users to sign in and sign out.
- Display usernames, avatars, scores, and leaderboard information.
- Maintain app functionality and user progress.
- Prevent abuse, fraud, unauthorized access, or misuse of the app.
- Improve app stability, security, and performance.
4. Sharing of Information
We do not sell your personal information. We may share information with service providers that help us operate the app, including authentication, hosting, database, analytics, crash reporting, or infrastructure providers.
If your username, avatar, or scores are shown on leaderboards or public profiles, that information may be visible to other users of the app.
5. Data Storage and Security
We use reasonable technical and organizational measures to protect user information. Data is transmitted using encrypted connections where supported. However, no method of transmission or storage is completely secure.
6. Data Retention
We keep your information for as long as needed to provide the app, maintain your account, comply with legal obligations, resolve disputes, and enforce our agreements. When your account is deleted, we delete or anonymize associated account data unless we are required to retain certain information by law or for legitimate security purposes.
7. Account Deletion
You can request deletion of your account and associated data from within the app or by contacting us at dczboomapps@gmail.com.
When an account is deleted, we will delete or anonymize your account information, including your username, avatar, and scores, where technically and legally possible. If leaderboard records are retained, they will be anonymized so they are no longer linked to your account.
8. Children’s Privacy
IQ Test Practice: Raven Matrices is not intended for children under the age required by applicable law to use online services without parental consent. We do not knowingly collect personal information from children without appropriate consent. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.
9. User Rights
Depending on your location, you may have rights to access, correct, delete, restrict, or object to the processing of your personal information. To make a request, contact us at dczboomapps@gmail.com.
10. International Processing
Your information may be processed and stored in countries other than your country of residence. These countries may have different data protection laws than your jurisdiction.
11. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the “Last updated” date above. Continued use of the app after changes means you accept the updated Privacy Policy.
