1. How We Collect Personal Information

To enable you to use our products and services normally, we collect your personal information in the following circumstances:

(1) Information You Provide to Us

When you register a Chisu account or use our products and services, you may provide us with personal information such as your name, ID number, phone number, email address, etc.
Information you share with third parties through our services, as well as information you provide, generate, or store while using our products and services.

(2) Information We Collect About You

Device Information: To deliver better products and improve user experience, we may collect device-related attributes, including your device model, operating system version, device configuration, unique device identifiers (e.g., IMEI, MAC address), location-related data (e.g., IP address, GPS coordinates, location derived from Bluetooth or Wi-Fi signals), and connection details (e.g., browser type, telecom carrier, language settings).
Log Information: When you use our website or client applications, our servers automatically record certain data as network logs. This may include usage patterns, IP addresses, URLs visited, browser types and languages, information about downloaded, installed, or used mobile apps, communication metadata, and timestamps of service access (date, time, duration, etc.).
Location Information: If you enable device location services and use our location-based features, we may collect and process precise or approximate location data using technologies such as IP geolocation, GPS, and nearby sensors (e.g., Wi-Fi access points, cell towers). You may disable location services at any time to stop this data collection, though doing so may limit your access to certain features or reduce their effectiveness.
Local Storage: We may use browser-based storage mechanisms (e.g., HTML5 local storage) and app data caching to collect and store information locally on your device.
Cookies and Similar Technologies: We may use cookies, beacons, proxies, and similar tracking technologies to understand your preferences and usage habits, conduct analytics, and enhance our services and user experience. We commit not to use cookies for purposes beyond those described in this Privacy Policy. You may configure your browser to reject cookies, but this may affect your ability to securely access or use certain Chisu services that rely on cookies.

2. How We Use Personal Information

We may use the information collected during the provision of our services for the following purposes:

Providing and Improving Products and Services
To operate, maintain, and enhance our existing offerings and develop new ones.
Personalizing Products and Services
To recommend content you may be interested in, including product updates, personalized recommendations, and marketing communications.
Ensuring Service Security
For identity verification, customer support, fraud detection, security monitoring, archiving, and backup—ensuring the safety and integrity of our services.
Other Purposes with Your Consent
If we intend to use your personal information for additional purposes not listed above, we will seek your explicit consent via notice and confirmation.

3. How We Store and Protect the Security of Your Personal Information

(1) Data Storage

In compliance with applicable laws and regulations, all personal information collected during our operations within China is stored within the People’s Republic of China. Currently, we do not transfer such data overseas. Should cross-border transfer become necessary, we will obtain your explicit consent in accordance with legal requirements. We retain your personal information only for as long as necessary to fulfill the purposes outlined in this Privacy Policy or as required by law.

(2) Data Security

We employ a range of technical and organizational security measures to prevent loss, misuse, unauthorized access, disclosure, alteration, or destruction of your information. For example, we use encryption to protect sensitive data you provide. However, please understand that due to technological limitations and potential malicious activities, no internet-based system can guarantee 100% security. Issues may arise from factors beyond our reasonable control, such as your own devices or communication networks.

4. Information We May Share

We treat your information with the utmost care and will not share it with any third party without your consent, except in the following circumstances:

With Affiliates, Partners, and Service Providers
We may share your information with our affiliates, partners, third-party vendors, contractors, and agents (e.g., email/notification providers, map services for location data) for the purposes of:
- Providing or improving the services you request;
- Fulfilling the uses described in Section 2;
- Performing our obligations and exercising our rights under the User Agreement or this Privacy Policy.
  Where we share your data with third parties, we will require them to comply with this Privacy Policy and implement appropriate confidentiality and security safeguards.
Business Transfers
In the event of a merger, acquisition, reorganization, asset sale, or similar transaction involving us or our affiliates, your personal information may be transferred as part of the deal. We will ensure confidentiality during such transfers and endeavor to ensure continued protection under comparable privacy standards. You acknowledge and accept this possibility.
Legal and Public Interest Disclosures
We or our affiliates may access, use, retain, or disclose your information when necessary to:
- Comply with legal obligations, court orders, or mandatory requests from government authorities;
- Detect, prevent, or address fraud, security breaches, or technical issues;
- Protect the rights, property, or safety of our customers, users, employees, affiliates, or the public, as permitted or required by law.

5. How You Can Access and Control Your Personal Information

We strive to provide you with reasonable means to access, update, and correct your registration information and other personal data provided during service use. You may log into your Chisu account to view or edit your profile. For security, identity verification, or legal compliance reasons, you may not be able to modify certain initial registration details.

6. Third-Party Services

While using our Services, you may interact with third-party services via software development kits (SDKs), links, or embedded features, which may involve necessary data sharing. These include:

Using the “Share” button to post content to third-party platforms. Such features may collect log data and place cookies on your device to function properly.
Links within our Services directing you to third-party websites or services.
Integration of third-party SDKs or applications to enhance functionality—for example:
- Push notifications and content recommendations;
- Collection of device and log information (with your consent);
- Third-party authentication (e.g., login via third-party accounts, sharing content externally);
- Support for features like live streaming or video-on-demand.

When you use these third-party services, you consent to their direct collection and processing of your information. We assess the legality, necessity, and fairness of such data practices and require third parties to implement adequate protections in compliance with applicable laws.

Note: These third-party services are operated independently by their respective providers. Your use of them—and any information you provide—is governed by their own terms and privacy policies, not this Privacy Policy. We strongly advise you to review their policies carefully. This Privacy Policy applies only to personal information collected by Chisu and does not govern third-party practices. If you identify risks in any third-party service, we recommend discontinuing its use and contacting us immediately.

7. Privacy Protection for Minors

We are committed to protecting the privacy of minors. If you are under the age of 18, we encourage you to ask your parent or legal guardian to read this Privacy Policy with you and to seek their consent and guidance before submitting any personal information.

8. Revisions and Updates to This Privacy Policy

To better serve you and comply with evolving user needs and legal requirements, we may update this Privacy Policy from time to time. Revised versions will be published on the Chisu official website or notified to you through other appropriate channels.

9. Publication and Effective Date

This Privacy Policy was published on June 3, 2023, and became effective on June 10, 2023.
