1. Introduction
This Privacy Policy explains how Qingkongshu Tech Limited ("we", "us", or "our") collects, uses, stores, and protects your personal information when you use our mobile game Tiles & Girls (the "Game"), which is available on the Google Play Store and developed with the Unity Engine. The Game is a single-player match-3 puzzle game with in-app purchases, no advertising, and is intended for users aged 13 years and older.
By downloading, installing, or using the Game, you acknowledge that you have read, understood, and agreed to the terms of this Privacy Policy. If you do not agree with this policy, please do not use the Game.
2. Age Restriction
The Game is intended for use by individuals aged 13 years or older ("Eligible Users"). We do not knowingly collect, solicit, or maintain personal information from children under the age of 13.
- We do not target the Game to children under 13.
- If we become aware that we have inadvertently collected personal information from a child under 13, we will immediately take steps to delete such information from our systems.
- For users aged 13 to 18 (teenagers), we recommend that you review this Privacy Policy with your parent or legal guardian and obtain their consent before using the Game, especially with regard to in-app purchases.
3. Data Collection and Usage
We adhere to the principle of "data minimization" – we only collect and use personal information that is necessary to provide and improve the Game, facilitate in-app purchases, and resolve technical issues. We do not collect information for advertising purposes, and we do not collect the Google Advertising ID (GAID).
3.1 Types of Data We Collect
| Data Type | What We Collect | Purpose of Collection |
|---|---|---|
| Device Information | Device model, operating system version, unique device identifiers (non-advertising), and device hardware specifications (collected in part by the Unity Engine). | To ensure the Game is compatible with your device, optimize game performance, and diagnose technical errors or crashes. |
| Game Activity Data | Game progress, level completion status, in-game achievements, and in-app purchase history (excluding payment card details). | To save your game state, provide access to purchased virtual items, and improve the overall gameplay experience. |
| Performance Data | Crash logs, error reports, loading times, and resource usage (CPU, memory) (collected in part by the Unity Engine). | To identify and fix bugs, optimize game performance, and enhance the stability of the Game. |
| Permission-Related Data | Only data related to necessary permissions (e.g., local storage access for game save files). | To enable local storage of game progress and ensure core Game functionality works as intended. We do not request unnecessary permissions. |
3.2 Data We Do NOT Collect
- Google Advertising ID (GAID) or any other advertising-related identifiers (including Unity's Advertising ID, which is disabled).
- Full name, email address, phone number, or other personally identifiable information (PII) unless voluntarily provided for support purposes.
- Credit card, debit card, or other sensitive payment information (handled exclusively by Google Play Billing).
- Location data, contacts, or media from your device.
4. Third-Party Services
We may use limited third-party services to support the core functionality of the Game. These third parties are bound by their own privacy policies, and we do not share any personal information with third parties for advertising or marketing purposes.
4.1 Key Google-Related Services
- Google Play Billing: This service is used to process in-app purchases. Google Play Billing handles all payment transactions, and we do not have access to your payment card details. For more information, please review Google's Privacy Policy: https://policies.google.com/privacy
- Firebase Crashlytics: This service is used to collect and analyze crash reports to improve Game stability. It collects device information and crash logs (non-personally identifiable). For more information, please review Firebase's Privacy Policy: https://firebase.google.com/support/privacy
4.2 Unity-Related Services (Engine and Core Tools)
The Game is developed using the Unity Engine (by Unity Technologies), which collects limited non-personally identifiable data to support game functionality, performance, and stability. We have disabled all Unity services related to advertising, analytics, and user tracking to align with our no-advertising privacy practices.
- Unity Engine (Core Runtime): The Unity Engine collects device information (model, OS version, hardware specifications) and game performance data (crash logs, frame rate, resource usage) to ensure the Game runs smoothly on your device and to identify technical issues. This data is not used for advertising, and no personally identifiable information (PII) is collected or shared. For more information, please review Unity Technologies' Privacy Policy: https://unity.com/legal/privacy-policy
- Unity In-App Purchasing (IAP) (optional, if used): If enabled, Unity IAP acts as a wrapper for Google Play Billing to process in-app purchases. It does not collect or store any payment card information (all payment processing is handled by Google Play Billing). Unity IAP only collects limited transaction metadata (e.g., purchase success/failure status) to verify in-app purchase entitlements. For more information about Unity IAP's privacy and service terms, please review Unity's Terms of Service (which includes IAP-related provisions): https://unity.com/legal/terms-of-service
- Unity Crash Reporting: This service collects anonymized crash logs and device information to help diagnose and fix Game crashes. It does not collect advertising identifiers or personally identifiable information, and data is only retained for the purpose of resolving technical issues. For more information, please review Unity's Crash Reporting Privacy Details: https://unity.com/legal/privacy-policy#crash-reporting
We do not integrate with any other Unity services that collect user data for advertising, analytics, or social sharing purposes.
5. Data Storage and Security
5.1 Storage Details
- Local Storage: Most game data (e.g., game progress, saved states) is stored directly on your mobile device. This data remains on your device unless you uninstall the Game or manually delete it.
- Cloud Storage: If you enable cloud sync (via Google Play Games), your game progress and in-app purchase history may be synced to Google's cloud servers. We do not store this data on our own servers, and Unity does not store this data on its cloud servers unless explicitly enabled (and disabled by default).
- Storage Duration: We retain data only for as long as necessary to fulfill the purposes for which it was collected, or as required by applicable law. In-app purchase records are retained to verify transactions and comply with Google Play and Unity requirements.
5.2 Security Measures
We take reasonable technical and organizational measures to protect your data from unauthorized access, disclosure, alteration, or destruction. These measures include:
- Encryption of data in transit (using TLS 1.3 for any cloud sync or error reporting, including Unity-related crash data).
- Local data encryption for sensitive game data (e.g., in-app purchase entitlements, implemented via Unity's local storage APIs).
- Restricted access to any collected data (only authorized personnel have access, and only for necessary purposes).
- Regular security audits and updates to the Unity Engine and Game to address potential vulnerabilities.
5.3 Data Deletion and Migration
To delete your game data:
- Local data: Uninstall the Game from your device, or use the "Clear Data" option in your device's app settings.
- Cloud-synced data: Follow Google's instructions to delete data associated with Google Play Games.
- Unity-related crash data: Contact Unity Technologies directly via their privacy portal, or contact us at duchunmeipp@gmail.com to request assistance with deleting anonymized crash data.
- To request deletion of any data we may have collected (e.g., support-related data), contact us at duchunmeipp@gmail.com.
6. User Rights
Depending on your country or region of residence (e.g., European Economic Area, California), you may have certain rights regarding your personal information, in accordance with laws such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
- Right to Access: You may request a copy of the personal information we hold about you.
- Right to Correction: You may request that we correct any inaccurate or incomplete personal information.
- Right to Deletion: You may request that we delete your personal information, subject to applicable legal obligations. For Unity-related data, you may also exercise your rights directly with Unity Technologies via their privacy portal.

To exercise these rights, please contact us at duchunmeipp@gmail.com. We will respond to your request within a reasonable timeframe (typically 30 days) as required by applicable law.
7. In-App Purchase Specifics
The Game offers in-app purchases for virtual items (e.g., game boosters, extra lives, or cosmetic items). All in-app purchases are processed exclusively through the Google Play Billing system, with Unity IAP (if used) acting as a non-data-collecting wrapper for this service.
- We do not collect, store, or process any of your payment card information – this is handled entirely by Google Play Billing (Unity IAP does not access payment details).
- All in-app purchases are final, unless eligible for a refund under Google Play's Refund Policy (e.g., accidental purchases, defective items).
- Teenagers (13-18 years old) must obtain parental or legal guardian consent before making any in-app purchases.
- You can view your in-app purchase history through your Google Play Store account.

8. No Advertising Commitment
The Game does not contain any form of advertising, including but not limited to banner ads, interstitial ads, rewarded video ads, or targeted ads.
We do not collect user data for advertising purposes, and we do not share any user data with ad networks, data brokers, or other third parties for advertising or marketing purposes. This includes disabling all advertising-related features in the Unity Engine to ensure no ad-related data is collected or shared. This commitment is a core part of our privacy practices and will be maintained for the lifetime of the Game (unless updated in this Privacy Policy with prior notice).
9. Privacy Policy Updates
We may update this Privacy Policy from time to time to reflect changes in our practices, legal requirements, the Game's functionality, or updates to Unity-related services. When we make material changes to this policy, we will:
- Update the "Last Updated" date at the top of this page.
- Provide at least 30 days' prior notice to you via an in-game pop-up notification or through the Google Play Store listing.
Your continued use of the Game after the effective date of the updated Privacy Policy constitutes your acceptance of the revised terms. We encourage you to review this Privacy Policy periodically for any changes.
10. Compliance with Google Play Requirements
This Privacy Policy is designed to comply with Google Play's Developer Program Policies, including the requirements for data disclosure, user privacy, and child safety. The content of this policy is consistent with the information provided in the Google Play Console's "Data Safety" section for the Game, including disclosures related to Unity Engine data collection.
We adhere to Google's principles of transparency and data minimization, and we do not engage in any practices that violate Google Play's privacy or security requirements. We also comply with Unity Technologies' service terms for non-advertising game development.
