Introduction
Welcome to Stereogram Quiz ("we," "our," or "us"), developed by Stupefying Labs. We are committed to protecting your privacy and ensuring you have a positive experience when using our application. This Privacy Policy explains how we collect, use, and protect information when you use our mobile application.
Information We Collect
Stereogram Quiz itself does not directly collect personal information. However, our app uses third-party services that may collect certain data:
1. Advertising (Google AdMob)
We display advertisements through Google AdMob to support our free app. Google AdMob may collect:
- Device Information: Device type, operating system version, unique device identifiers (Advertising ID)
- Usage Data: Ad interaction data, app usage patterns for ad personalization
- Network Information: IP address, network carrier information
Google's use of advertising data is governed by Google's Privacy Policy.
2. In-App Purchases (Google Play Billing)
Our app offers in-app purchases through Google Play Billing for:
- Purchasing virtual coins for in-app features (freeze timer, skip questions)
- Unlocking game modes (Normal Mode, Hard Mode)
Purchase transactions are processed entirely by Google Play. We do not collect or store any payment information. Google Play's handling of payment data is governed by Google's Privacy Policy.
3. Analytics and Crash Reporting (Firebase)
We use Firebase Analytics and Firebase Crashlytics to improve our app:
- Firebase Analytics: Collects anonymous usage statistics such as app opens, feature usage, and session duration to help us understand how users interact with the app
- Firebase Crashlytics: Collects crash reports and error logs to help us identify and fix bugs. This may include device information, app version, and crash stack traces
Firebase's data practices are governed by Google's Privacy Policy.
