Stack Fever — Privacy Policy
**Last Updated: May 14, 2026**
1. Introduction
Welcome to **Stack Fever** ("the App"), a mobile game developed and operated by **Vivek Pansheriya , Dark Lava** ("we," "us," or "our").
This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App. By downloading or using Stack Fever, you agree to the practices described in this policy.
If you do not agree with any part of this Privacy Policy, please discontinue use of the App immediately.
2. Information We Collect
2.1 Information You Provide
- **Player Nickname:** A custom username (up to 12 characters) you enter voluntarily. This is stored locally on your device and shared to our leaderboard.
2.2 Information Collected Automatically
**Game Data:**
- Your game scores, high scores, blocks placed, perfect hits, combo counts, and XP/level progress.
- Daily play streaks and achievement unlock events.
- These are stored locally on your device (AsyncStorage / SecureStore) and, for leaderboard purposes, synced to our Firebase Realtime Database.
**Anonymous Authentication:**
- The App uses Firebase Anonymous Authentication to assign each device a unique anonymous user ID (UID). This UID is used exclusively to associate your leaderboard score with your account. No email, phone number, or personal identity is required or collected.
**Device & Technical Information:**
- Device operating system type (Android/iOS) and version.
- App version and crash/error information.
**Advertising Data (via Google AdMob):**
- The App displays advertisements provided by **Google AdMob** to support free access.
- AdMob may collect your **Advertising ID (GAID on Android / IDFA on iOS)** and use it to serve personalized or interest-based ads, depending on your device consent settings.
- The App requests **non-personalized ads by default** (`requestNonPersonalizedAdsOnly: true`), meaning no interest-based profiling is performed by the app itself.
- For information on how Google uses advertising data, please review Google's Privacy Policy: https://policies.google.com/privacy
**Push Notifications:**
- If you grant notification permission, we may send you push reminders to maintain your daily play streak. You can revoke this permission at any time in your device Settings.
**Media Library:**
- The App requests photo library access only when you choose to save or share a screenshot of your tower. No photos are ever uploaded to our servers.
3. How We Use Your Information
We use collected information to:
- Display your nickname and score on the global leaderboard
- Track your game progress, missions, and achievements locally
- Deliver and measure advertisements through Google AdMob
- Send optional streak-reminder push notifications
- Detect and fix bugs and crashes
- Improve game balance and difficulty through aggregate (non-personal) analytics
4. How We Share Your Information
We do **not** sell your personal information.
We share information only with the following third-party services that are essential to App operation:
| Service | Purpose | Privacy Policy |
| **Google Firebase** | Anonymous auth, leaderboard database, crash reporting | https://firebase.google.com/support/privacy |
| **Google AdMob** | Advertisement delivery and measurement | https://policies.google.com/privacy |
Your player nickname and high score are visible to other users on the global leaderboard.
5. Children's Privacy
Stack Fever is intended for users **13 years of age and older**.
We do not knowingly collect personal information from children under 13. The App does not contain child-directed advertising and does not qualify as a "child-directed" app under COPPA or GDPR-K.
If you are a parent or guardian and believe your child under 13 has provided personal information through the App, please contact us (see Section 9) and we will promptly delete that information.
6. Advertising and Your Choices
**Google AdMob** serves ads within the App. You can opt out of interest-based advertising by:
**Android:** Go to Settings → Privacy → Ads → Delete Advertising ID
**iOS:** Go to Settings → Privacy & Security → Tracking → disable tracking
Opting out means you will still see ads, but they will not be based on your interests.
7. Data Retention
| Data Type | Retention |
| Local game data (scores, settings) | Until you uninstall the App |
| Firebase leaderboard entry (UID + score + nickname) | Until you delete your account or contact us for deletion |
| Anonymous Firebase Auth UID | Until account deletion is requested |
| AdMob advertising data | Controlled by Google's own retention policies |
To request deletion of your leaderboard data and Firebase account, contact us using the information in Section 9.
8. Your Rights
Depending on your location, you may have the following rights:
- **Access:** Request a copy of the data we hold about you.
- **Correction:** Ask us to correct inaccurate data.
- **Deletion:** Ask us to delete your data ("right to be forgotten").
- **Restriction:** Ask us to limit how we use your data.
