This Privacy Policy (“Policy”) explains how LIU DINGXING (“we,” “our,” or “us”) collects, uses, discloses, and protects your personal information when you use our mobile application on iOS devices (the “App” or “Service”). By downloading, installing, or using the App, you agree to the collection and use of information as described in this Policy. If you do not agree to this Policy, please do not use the App.
We collect information to provide, maintain, and improve the App’s functionality and user experience. The types of information we collect include:
A. Automatically Collected Information
When you use the App, we automatically collect certain technical data sent by your iOS device, particularly in the event of errors or crashes. This includes:
Your device’s Internet Protocol (IP) address
Device name and model (e.g., iPhone, iPad)
iOS operating system version
App configuration details and crash logs
Time and date of use
Usage statistics (e.g., features accessed, session duration)
B. Personal Information Collected with Consent
While using the App, we may ask you to voluntarily provide certain personally identifiable information (e.g., name, email address, phone number) to contact or identify you. This information is collected only with your explicit consent and is used solely for the purposes disclosed at the time of collection.
C. Third-Party Data Sharing and SDKs
Our App may integrate with third-party services and Software Development Kits (SDKs) to enhance functionality, serve advertisements, and analyze performance. These services may collect data as described below:
Google Play Services / Firebase: Analytics, app distribution, and crash diagnostics.
AdMob / AppLovin: Serving, mediating, and analyzing advertisements.
Facebook SDK: Social login, sharing features, and analytics.
Unity: Game engine services and performance monitoring.
These third parties are obligated to retain and process your data in compliance with their own privacy policies and applicable laws. We do not control their data retention practices but require them to process data only for the purposes specified in this Policy.
We will retain your personal information and automatically collected data for a maximum of 90 days, unless a longer retention period is required:
To comply with a legal obligation (e.g., regulatory requirements or court orders).
To establish, exercise, or defend legal claims (e.g., in case of disputes).
To protect the safety, rights, or security of our users or the App (e.g., investigating fraud or technical issues).
After 90 days, or once the retention purpose has ceased, we will delete or anonymize your data to the extent technically feasible. If you request the deletion of your data prior to the 90-day period, we will comply promptly unless subject to a legal exception.
While our App does not use traditional web cookies, third-party SDKs integrated into the App may employ tracking technologies to collect information. You can manage and control these technologies through your iOS device settings (e.g., limiting ad tracking) or through the third parties’ own opt-out mechanisms.
We implement reasonable administrative, technical, and physical security measures to protect your personal information. However, please be aware that no method of transmission over the internet or electronic storage is 100% secure. We cannot guarantee absolute security and are not liable for third-party breaches beyond our reasonable control.
The App may contain links to external websites or services. We are not responsible for the privacy practices, content, or security of these third parties. We strongly encourage you to review their privacy policies before engaging with them.
The App is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have inadvertently collected personal data from a child under 13, we will take immediate steps to delete such information.
Depending on your location, you may have certain rights regarding your personal information, including the right to access, correct, or delete your data. To exercise these rights, please contact us using the information provided below.
We may update this Policy from time to time to reflect changes in our practices, technology, or legal requirements. Any changes will be posted on this page with an updated “Last Updated” date. For significant amendments, we will notify you via an in-app notice or email. We encourage you to review this Policy regularly.
