Privacy Policy
Effective Date: August 18, 2026
This Privacy Policy describes how IQ Test ("we", "us", or "our") collects, uses, stores, and shares information when you use our mobile application ("App").
1. Information We Collect
A. Information You Provide
- Nickname / Display Name: If you choose to submit your scores to the online leaderboard, you may provide a custom nickname. If no nickname is entered, scores are submitted under "Anonymous".
B. Information Automatically Collected by the App
- Installation Identifier: The App generates a random installation UUID stored locally on your device in shared preferences. This ID is used solely to identify your submitted scores on the Firebase leaderboard and allow you to manage/delete your scores.
- Test Scores & Leaderboard Entries: Your test results, date, and score values submitted to public daily, weekly, or all-time leaderboards.
- Anonymous Statistical Data: We collect test results to generate overall population statistics and score distributions. Test results used for statistical analysis are aggregated anonymously with data from other users and cannot be linked back to you or your identity.
C. Information Collected by Third-Party Services (Google AdMob)
Our App uses Google Mobile Ads (AdMob) to display advertisements. AdMob automatically collects certain information, including:
- Device Identifiers: Android Advertising ID (AAID).
- Approximate Location: General location derived from your IP address to deliver geographically relevant ads.
- App Activity & Ad Interactions: Views, taps, and clicks on displayed advertisements.
- Diagnostics: SDK performance data, latency, and operational logs.
2. How We Use Your Information
We use the collected information for the following purposes:
- App Functionality: To record and display your scores and chosen nickname on public leaderboards.
- Anonymous Statistics: To calculate general score percentiles, averages, and statistical norms. These test results are strictly aggregated and cannot be linked back to individual users.
- Score Management: To allow you to delete your submitted high scores directly from the Leaderboard screen.
- Advertising & Marketing: To serve personalized or non-personalized advertisements via Google AdMob.
- Analytics & Fraud Prevention: To ensure ad delivery integrity, prevent click fraud, and monitor SDK performance.
3. Data Sharing & Third-Party Services
We do not sell, rent, or trade your personal information. Data is shared with third-party service providers only as necessary to operate the App:
4. Data Security
All communications between the App and Firebase/AdMob servers use HTTPS / TLS encryption in transit. Data stored in Firebase Firestore is encrypted at rest using industry-standard AES-256 encryption.
5. Data Control & Deletion Rights
You have full control over the data submitted by your device:
- In-App Score Deletion: You can delete your submitted scores at any time directly within the App's Leaderboard screen by tapping the Delete icon next to your score entry.
- Advertising ID Controls: You can reset or delete your device’s Advertising ID at any time through your Android device settings (
Settings ➔ Privacy ➔ Ads).
- Contact Request: You may also contact us by email to request manual deletion of any submitted leaderboard data associated with your device.
6. Children's Privacy
Our App is intended for general audiences and does not knowingly collect personal identifiable information from children under the age of 13. If you believe a child has provided us with personal information, please contact us so we can promptly delete it.

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Effective Date".
