II. Information We Collect
To provide you with a stable, high-quality, and personalized gaming experience, we may collect the following categories of information within the scope permitted by law, as necessary for the service, and with your explicit consent. Some of this information is essential for providing basic services—if you refuse to provide it, we may not be able to guarantee the normal operation of the Game's core functions. Other information will be collected and processed based on your voluntary provision or explicit authorization:

This information is used to identify devices, ensure stable service operation, and conduct basic data analysis.
2. Game Behavior Data
Including but not limited to your game progress, achievement records, application version number, level attempt counts and completion status, online duration, login and logout times, feature clicks and interaction flows, resource consumption records, exception crash logs, and performance data. This information is used to analyze user behavior patterns, optimize product design, and enhance user experience.
3. Information You Voluntarily Provide
When you actively contact us through customer service channels (including but not limited to email at service@circuitlink.com), we may collect the feedback content, consultation questions, complaints and suggestions, contact information (e.g., email address, social media account), and other attachments or explanatory materials you choose to provide. We will strictly limit the use of such information solely for processing your requests, improving service quality, and fulfilling legal obligations.
4. Cookies and Similar Technologies
We and our third-party partners may use cookies, web beacons, embedded scripts, local storage, SDKs, and similar technologies to assign unique identifiers to you, maintain your login status, record preference settings, conduct product analysis, optimize advertising delivery strategies, and implement advertising anti-fraud verification. You may manage or disable such technologies through your browser or device system settings; however, this may affect the normal use of certain features.
III. How We Use Information
We commit to using the collected information strictly for the following purposes, within the scope necessary to achieve such purposes, and will not process your personal information beyond that scope:

3. Personalized Advertising and Content Recommendations
With your explicit authorization, we may share necessary device identifiers with industry-standard third-party advertising partners (such as Facebook, AdMob, Unity Ads, etc.) to provide you with more relevant and valuable advertising content. You have the right to withdraw this authorization at any time; withdrawal does not affect the legality of advertising activities already conducted based on your prior consent.

Preventing, detecting, and responding to fraudulent activities, abnormal operations, cyberattacks, and other potential security threats; ensuring system architecture stability and controlled data access; fulfilling applicable laws and regulations, court orders, regulatory requirements, and other legal obligations.
5. Statistical Analysis and Market Research
We may de-identify, anonymize, or aggregate personal information so that it cannot directly or indirectly identify specific individuals. Such information will be used for macro-level user behavior analysis, market trend research, business decision support, academic research, and other legitimate purposes.
IV. Information Sharing and Disclosure
We highly value your trust and commit that we will not sell, rent, or unlawfully trade your personal information. We may only share necessary data with third parties under the following necessary circumstances and in strict compliance with laws, regulations, and this Policy:

2. Advertising Partners
With your explicit consent, we may share non-directly identifiable information, such as device identifiers, with compliant advertising networks for ad delivery, performance measurement, and frequency capping. The data processing practices of advertising partners are governed by their own privacy policies, and we recommend that you review the relevant terms.

We will notify you of such changes through appropriate means (e.g., in-game announcements, email notifications) and require the recipient to continue to be bound by this Policy; otherwise, we will require them to seek your authorization anew.

VI. Information Security Measures
We adopt industry-standard security technologies, systems, and procedures to comprehensively protect the security of your personal information and prevent unauthorized access, disclosure, use, modification, destruction, or leakage of data:
1. Technical Measures
Employing HTTPS encrypted transmission protocols to ensure the confidentiality and integrity of data during network transmission;
Implementing a least-privilege access control policy to strictly limit the data access scope of internal personnel and third-party service providers;
Deploying firewalls, intrusion detection systems, and anti-virus software to defend against malicious attacks;
Conducting regular security vulnerability scans, penetration tests, and compliance assessments.
2. Administrative Measures
Establishing a data security management system that clearly defines data classification and grading, access approval, and emergency response procedures;
Signing confidentiality agreements with employees and partners to enforce information security responsibilities;
Conducting regular privacy protection and security awareness training to enhance internal compliance capabilities.
3. Risk Notification
Please be aware that no method of internet transmission or electronic storage can guarantee 100% absolute security. Despite our implementation of reasonable and effective security measures, we cannot completely eliminate security risks arising from technological limitations, novel attack methods, or force majeure. We strongly recommend that you properly safeguard your personal devices, system passwords, and account information, and avoid downloading, installing, or using this Game through unofficial channels to collectively maintain your data security.
VII. Information Retention Period
We retain your personal information only for the shortest period necessary to achieve the purposes described in this Policy, unless otherwise required by laws and regulations or unless you authorize an extension of the retention period. The specific retention period is determined according to the following criteria:
Service Necessity: During your use of this Service, we continuously retain your game progress and related behavioral data until you uninstall the Game or actively request deletion.
Legal Obligations: Where laws and regulations such as those concerning taxation, auditing, or anti-fraud require longer data retention periods, we will retain the information as required by law.
Dispute Resolution: If there are pending complaints, disputes, or legal proceedings, we will continue to retain relevant information for the necessary duration.
Upon exceeding the aforementioned retention periods, we will delete, anonymize, or irreversibly destroy your personal information in accordance with the law.

Guardians should supervise and guide the gaming behavior and related personal information processing of the minors in their care.

Upon verification, we will promptly take measures to delete the information and terminate services for that child.
