Privacy Policy
This privacy policy applies to the "Screw Sorting Master" application (package name: master.screw.puzzle.pin.sort.match, hereby referred to as "Application") for mobile devices. It was created by zhanghr (hereby referred to as "Service Provider") as a Free service with in-app purchases and advertisements. This service is intended for use "AS IS".
1. Information Collection and Use
The Application automatically collects certain information when you download and play it to ensure gameplay stability and optimize user experience. This information includes:
· Your device's Internet Protocol address (e.g., IP address)
· Device identifiers, including Advertising ID (such as Google Advertising ID / GAID)
· Mobile device details (e.g., device model, operating system version, and system language)
· Gameplay progression and event logs (e.g., levels cleared, puzzle completion times, and features used)
· In-app purchase history and order timestamps
The Application does not gather precise, real-time geographic location information of your mobile device.
2. In-App Purchases (IAP) and Financial Data
The Application offers virtual goods (such as removing ads, purchasing tickets, or in-game props) via in-app purchases. All financial transactions and payment processing are securely handled by the Google Play Store (Google LLC).
The Service Provider does not collect, store, or have access to your credit card details, bank account numbers, or billing addresses. We only receive a secure payment confirmation token from Google to unlock the purchased virtual goods on our game servers.
3. Advertising (IAA) and Behavioral Tracking
The Application displays third-party advertisements (such as banners, interstitials, and rewarded videos) to fund the development and operational costs.
Third-party ad networks may use tracking identifiers (like GAID) to serve personalized or contextual advertisements based on your interests. You can opt-out of personalized advertising at any time by adjusting your mobile device settings (e.g., "Opt out of Ads Personalization" or "Reset Advertising ID" in Android settings).
4. Third-Party Service Providers
The Application integrates industry-standard third-party Software Development Kits (SDKs) to provide core game services, ads, and analytics. These external services have their own independent Privacy Policies:
· Google Play Services: https://policies.google.com/privacy
· AdMob: https://support.google.com/admob/answer/6128543
· Google Analytics for Firebase: https://firebase.google.com/policies/analytics
· Firebase Crashlytics: https://firebase.google.com/support/privacy
5. Information Disclosure
The Service Provider may disclose automatically collected or user-provided information only under the following circumstances:
· As required by law, such as to comply with a subpoena or similar legal process.
· When they believe in good faith that disclosure is necessary to protect their rights, your safety, or the safety of others, to investigate fraud, or to respond to a official government request.
· With trusted service providers who work on our behalf, do not have an independent use of the information disclosed, and have agreed to adhere to strict data protection rules.
6. Data Retention and Deletion Rights
The Service Provider will retain gameplay logs, purchase tokens, and analytical data for as long as you keep the Application installed and for a reasonable time thereafter.
If you wish to request the immediate erasure of any personal data or game account history associated with your device, please contact us via email at zhanghrmother@gmail.com. We will process and fulfill your deletion request within a reasonable time frame.
7. Children's Privacy (Families Policy)
The Application is not designed for or intentionally directed to children under the age of 13 (or under 16 in the European Economic Area). The Service Provider does not knowingly collect personally identifiable information from children under these age limits.
If we discover that a child under 13 has provided personal data, we will immediately delete it from our servers. If you are a parent or guardian and realize your child has shared information with us, please contact us at zhanghrmother@gmail.com so we can take the necessary legal actions.
