1. SUMMARY

• The App does NOT collect, store, or process personal data from players.
• All game progress and settings are stored locally on your device only.
• We do not run ads and do not use analytics or crash reporting services.
• The only external processing occurs through Google Play when handling purchases.

2. WHAT DATA WE COLLECT

We do NOT collect any personal data directly. The only data that may be processed are:

• In-app purchase information: When you buy content (e.g., expansions, coin packs), Google Play provides us with the purchase confirmation (product ID, token, timestamp). This is required to deliver the purchased content.

We do NOT receive or store your payment details (such as credit card numbers). Payment is handled solely by Google Play.

3. SOURCES OF DATA

• Google Play Billing: provides purchase confirmations so we can unlock your content.

No other data sources are used.

4. WHY WE PROCESS YOUR DATA

• To deliver the content or feature you purchased.
• To restore purchases if you reinstall the App or switch devices.

5. LEGAL BASES (EEA/UK GDPR)

• Contract (Art. 6(1)(b)): we need to process your Google Play purchase confirmation to deliver the item you bought.
• Legal obligation (Art. 6(1)(c)): we may need to retain basic transaction information for accounting and tax purposes.

6. DATA SHARING AND RECIPIENTS

7. INTERNATIONAL TRANSFERS

If Google processes purchase information outside your country, such transfers are governed by Google's own compliance frameworks (e.g., Standard Contractual Clauses).

8. RETENTION

• Purchase records: kept as long as required for legal and accounting purposes.
• Game data: only on your device; you control deletion by uninstalling or clearing the App data.

9. YOUR RIGHTS

Depending on your region (e.g., GDPR in the EEA/UK, CCPA in California, LGPD in Brazil), you may have rights to access, correct, or delete your data. Since we do not collect or store personal data, most requests can be addressed by uninstalling the App. For purchase records, please contact Google Play support.

You can also contact us at enlyzr@gmail.com for any privacy-related questions.

10. CHILDREN'S PRIVACY

The App is suitable for users ages 9 and up. We do not knowingly collect personal data from any users, including children. If you believe a child has provided personal data, please contact us and we will promptly address the issue.

11. SECURITY

We do not store your personal data. Google Play Billing processes payments securely using its own systems.

12. CHANGES TO THIS POLICY

We may update this Policy if our practices change (e.g., if new features require data). Updates will be published in-app, on our website, and on https://enlyzr.info/dualsum_sudoku_privacy_policy.html.
