Effective date: October 8, 2026

Quartets ("we", "our", "us") respects your privacy. This Privacy Policy explains what data we collect, how we use it, and your choices.

1. Data We Collect

A) Personal Info

• Email address (if you sign in)

• User ID (Firebase user identifier)

B) App Info and Performance

• Crash logs

• Diagnostics

C) App Activity

• App interactions (for analytics and app improvement)

D) Device or Other IDs

• Google Advertising ID and other device identifiers, used for analytics, security, and advertising

2. How We Use Data

We use collected data for:

• App functionality — sign-in, account features, saving progress

• Account management

• Fraud prevention, security, and compliance

• Analytics — understanding usage, improving performance, fixing issues

• Advertising and marketing — showing ads and measuring their performance through Google AdMob

3. Data Sharing

We may share limited data with service providers that help operate the app:

• Google Firebase — Authentication, Analytics

• Google AdMob — advertising

AdMob may collect device identifiers, IP address, and information about the ads shown to you and how you interact with them, for the purposes of serving and measuring ads.

We do not sell personal data.

4. Advertising

This app displays advertisements served by Google AdMob, which uses the Google Advertising ID and other device information to select and measure ads.

You can control personalized advertising through your device's Google Play settings, including the option to reset or delete your advertising ID. Removing the advertising ID does not stop ads from being shown — it only stops them from being personalized.

5. Data Security

Data is encrypted in transit using secure protocols.

6. Data Retention

We keep data only as long as needed to provide app functionality, legal compliance, security, and support.

7. Your Rights and Data Deletion

You can request deletion of your account and associated data: https://sites.google.com/view/privacypolicyforgoldsilverpric/quartest-delete

You can also request deletion of certain app data without deleting your whole account: https://sites.google.com/view/privacypolicyforgoldsilverpric/quartest-delete

8. Children's Privacy

This app is not directed to children under 13. If you believe a child provided personal data, contact us to remove it.

9. Changes to This Policy
