Privacy Policy

Last updated: May 18, 2026

ChemPlay ("we", "our", or "us") is dedicated to protecting your privacy. This Privacy Policy outlines how your information is collected, used, protected, and your choices regarding data when using the ChemPlay mobile application.

1. Information We Collect

ChemPlay collects minimal and necessary information to provide, maintain, and optimize our educational game services:

Usage & Performance Data: We collect anonymous interactive events (such as game level completions, high scores, active gameplay duration, and chemistry level choices) to analyze game difficulty and design progression.
Advertising Identifiers: We display advertisements through Google AdMob for free tier users. AdMob may utilize standard mobile advertising identifiers (such as Android AD ID or iOS IDFA) to serve personalized and safe ads.
Technical Diagnostics: To resolve bugs, we collect automatic, anonymized stack traces and crash reports when unexpected errors occur.

2. Use of Data

We process collected data to achieve the following operational purposes:

To operate, maintain, and deliver the core gameplay experience.
To record, persist, and restore your game progress, level unlocks, and Premium Lifetime purchase status locally.
To monitor app performance, identify crash bottlenecks, and deploy bug fixes.
To serve relevant, non-intrusive advertisements to players on the free tier.

3. Data Encryption & Security

We prioritize the safety of your information. All communication and data transmission inside ChemPlay are fully encrypted in transit using secure Industry Standard protocols (HTTPS / SSL/TLS). Your data remains encrypted and safe from interception while traveling over the internet.

4. Third-Party Services

To power dynamic gameplay and maintain game stability, we integrate trusted third-party SDKs that process anonymized data under their own respective privacy policies:

Google AdMob: Serves standard advertisements on the free tier.
Google Firebase Analytics: Helps us understand player engagement, level retention, and game flows to improve design.
Google Firebase Crashlytics: Records anonymous crash reports, allowing us to fix critical bugs rapidly.
Apple App Store & Google Play: Process all in-app billing transactions and Premium upgrade verify checks securely.

5. Your Choices & Data Deletion

Since ChemPlay does not require or support account creation, email registration, or store personal user profiles on external servers, no personal account deletion is necessary. You can easily reset your local game progress and local settings at any time directly through the app settings, or by reinstalling the application. If you have any inquiries, please contact us at daip6690@gmail.com.

6. Children's Privacy

ChemPlay is an educational chemistry game designed for a general student audience. We do not knowingly collect personally identifiable information from children under 13 without appropriate guardian knowledge. If you believe a child has provided us with personal data, please contact us so we can delete the information immediately.
