1. Introduction
Thank you for using Happy Sudoku (the "App"), a clean, ad-free Sudoku
puzzle game developed by an independent developer.
Our Core Promise: This App contains no advertisements, no
third-party tracking SDKs, and does not collect any personally identifiable
information for marketing, analytics, or commercial purposes.
This Privacy Policy explains what minimal technical information may be processed, how it
is used, and your rights regarding your data. By downloading, installing, or using the
App, you agree to the terms described herein.
2. Information We Do Not Collect
We explicitly commit that the App does not collect:
- Your name, phone number, email address, ID number, or other personal
identifiers
- Contacts, SMS, call logs, photos, or other personal content
- Precise location data, sensor data, or browsing history
- Advertising identifiers (e.g., GAID, IMEI, OAID, IDFA)
- Your game progress, puzzle history, or preferences (stored locally only)
3. Technical Information Processed via Google Play
When the App encounters an unexpected crash, Google Play Console's built-in crash
reporting may automatically collect anonymized technical logs to help us
improve stability. This data is collected and processed solely by Google, not by the App
itself.

Important Notes:
- These logs are collected automatically by Google Play services;
the App does not actively request or transmit personal data.
- All crash data is stored on Google's secure servers. Developers
only view aggregated, anonymized reports via Google Play Console—no
individual user can be identified.
- This information is used exclusively for technical debugging and
stability improvement. It is never used for advertising, profiling, or
commercial analytics.
4. Data Storage & Protection
4.1 Storage Location
- Local Data: Your game progress and settings are stored only on your
device and never uploaded.
- Crash Logs: Processed and stored by Google LLC on its global
infrastructure, potentially involving cross-border data transfers. Google complies
with applicable data protection laws (e.g., GDPR, CCPA).
4.2 Retention Period
- Local game data: Retained until you clear app data or uninstall the App.
- Google Play crash logs: Retained per Google's Data Retention Policy for technical analysis
purposes.
4.3 Security Measures
We and Google employ industry-standard safeguards (encryption in transit, access
controls, anonymization) to protect technical logs from unauthorized access or
disclosure.
5. Information Sharing & Disclosure
We do not sell, rent, trade, or otherwise share your information with any third
party.
The only exceptions are:
- Platform Processing: Crash reporting is handled by Google Play
under its Privacy Policy.
- Legal Requirements: If required by law, regulation, judicial
process, or government authority, we may disclose information to the extent legally
mandated.
6. Your Rights & Choices
- Manage Local Data: View or delete game progress via in-app settings
or by uninstalling the App.
- Control Crash Reporting (Android): You may disable crash reports at
the system level via Settings → Google → All Services → Crash reports (path
may vary by device).
- Withdraw Consent: You may stop using and uninstall the App at any
time. Local data will be automatically removed.
- Contact Us: Exercise your rights or ask questions by emailing us
(see Section 8).
7. Children's Privacy
Happy Sudoku is a family-friendly puzzle game suitable for all ages.
- If you are under 13 (or under 16 in certain regions), please use the App under
parental supervision.
- We do not knowingly collect personal information from children. If we become aware
of such collection, we will take steps to delete the data promptly.
8. Policy Updates
We may update this Privacy Policy periodically. Changes will be communicated via:
- In-app notification or banner
- Updated listing on Google Play Store
- Direct email (if you have previously contacted us)
Your continued use of the App after changes take effect constitutes acceptance of the
updated policy.
