The HiQ platform products and services utilize a unified account system. When you register for a HiQ account, you must provide at least a username, mobile phone number, and/or email address, and create a password. If you only need to use basic services available without logging in, you have the right to choose not to register and not to provide the above information.

To comply with mandatory legal requirements or to use specific product features, when you are using certain specific products that require you to fill in your mobile number for account registration, we may display the mobile number linked to your HiQ account by default for your convenience. You can modify this information based on the corresponding product features. To ensure a consistent experience across HiQ products based on the same account, your account's follow and follow-back records in one HiQ product may be recorded under your HiQ account and displayed when you log into other related products. This service is realized based on the 'integration' clause but does not constitute a mandatory obligation of HiQ regarding data.

Apart from identifying your identity, the registration information will also be used in other service-related scenarios. For instance, we may use the collected information (such as your mobile number, email address) to communicate or interact with you directly; if we or companies using the HiQ account system detect suspicious activities (such as attempts to log into your HiQ account from an unusual location), we may send you notifications; or we or companies using the HiQ account system may contact you to inform you about upcoming changes or improvements to the services provided to you, or to invite you to participate in new product experiences.

To ensure the safety of your account and property, and to conduct risk control and defense, when you register/login to your account, we collect your device information and information related to the registration/login environment (including International Mobile Equipment Identity (IMEI), Identifier for Advertisers (IDFA), Integrated Circuit Card Identifier (ICCID), device name, device model, operating system version, Wi-Fi information BSSID, SSID, and IP address information).

In some products, you can also log in using third-party accounts (such as WeChat, Weibo, QQ). In this case, you will authorize the product to access your publicly registered information on that third-party account (including your nickname, avatar, and other authorized information).

For some products, we provide you with a 'one-click login' option, allowing you to choose to log in via 'one-click login,' which is provided by the carrier. If you choose this login method, the carrier will process your mobile number information. We cannot obtain your plain text mobile number before you actively log in.

To meet mandatory legal requirements, or for the necessity of providing products or services, or based on your need for enhanced account protection, you need to provide your real name, ID number, and facial information to complete account real-name verification when using certain services or if you have further needs. If you do not conduct real-name verification, it may impact your ability to use business functions that require real-name verification. To verify the accuracy and completeness of the information you provide, or to ensure the security of your account, we may compare the real-name information you provide to HiQ with your corresponding information stored by authorized institutions or government agencies as permitted by law. To ensure the safety of your account and maintain consistency in real-name verification while providing you with convenient services, once your HiQ account completes real-name verification, the above real-name information will serve as the universal verification information for that account across all products accessing HiQ account services. To protect your personal information, please do not transfer or lend your account to others. If the processing exceeds the scope mentioned above, unless otherwise stipulated by laws and regulations, the personal information processor will obtain your consent in accordance with legal requirements.

Based on the different service content you choose, during the service provision process, we may collect relevant personal information about how you use the product and/or service (including usage methods) to achieve service purposes. When some services are jointly provided to you by HiQ and third parties, we and third parties may jointly process your personal information as necessary for providing services.

The categories and content of personal information required for service provision are specific to the services and features you enable, generally including:

Integration and Fusion: In the products and services of the HiQ platform, while ensuring that personal information is controlled under the same business entity and maintaining data security capabilities and management levels, you agree that we will use our own or entrusted technologies to integrate, analyze, and further process the personal information you actively or passively provide in HiQ platform products and services. This will form label information that reflects your behavioral habits, interests, or economic, health, credit status, and identity characteristics (hereinafter referred to as 'Label Information'). We will use this label information for automated decision-making in specific scenarios and purposes, and to push personalized display information and/or commercial marketing information to you. We will ensure the secure processing of information after integration and fusion. To provide you with consistent service, we may associate your device information or phone number with your HiQ account after obtaining your authorization, linking and integrating the personal information provided actively or passively across different devices for the same account.

To enhance the security of your use of products and services provided by our affiliates and partners, we may use your information for identity verification, customer service, security prevention, fraud monitoring, credit analysis, and other purposes to prevent, detect, and/or investigate fraud, threats to security, and other illegal or violation of our agreements, policies, or rules behaviors, protecting your, other users', our affiliates', partners', and the public's legitimate rights and interests. To prevent and resist the publication and dissemination of illegal and harmful information, we use computer algorithm models to automatically calculate and analyze online content; if we find that the content contains illegal or harmful information, we will immediately cease transmission and take action.

We may use the information collected to improve our products and services and conduct necessary business operations and analytical research, such as operating products or providing services, evaluating, maintaining, and improving product and service performance, developing new products and services, and providing customer support. To improve the products and services of us and our affiliates and partners, we may also conduct statistical analysis on product usage. Additionally, HiQ may share these statistics with the public to showcase overall usage trends of our services, but these statistics will not contain any identifiable information about you.

To reasonably improve the security and personalization of product services, we may receive your personal information and other information from various product and service providers on the HiQ platform, affiliates, partners, and other trusted third-party suppliers, in accordance with laws and regulations or based on your valid authorization, and we may further process this information. We will require personal information providers to clarify the source of personal information and confirm its legality, ensuring that our processing of your personal information has a sufficient legal basis. For instance, if we process your personal information based on consent and the processing activities exceed the scope of consent obtained, we will seek your consent within a reasonable timeframe after obtaining the personal information or before processing it.

We may conduct personal information processing activities for other specific purposes necessary for providing different products or services. You can refer to the specific privacy policy of HiQ products or contact us for clarification.

We will only publicly disclose your personal information under the following circumstances:

1. We have obtained your separate consent;

2. Based on legal regulations, legal procedures, litigation, or mandatory requirements of government authorities.

In the following circumstances, we can share, transfer, or publicly disclose your personal information without prior authorization:

1. Necessary for fulfilling statutory duties or legal obligations (such as legal obligations directly related to national security, defense security, criminal investigation, prosecution, trial, and execution of judgments);

2. Necessary to respond to public health emergencies or to protect the life, health, and property safety of individuals in emergencies;

5. Necessary for public interest actions such as news reporting and public opinion supervision, processing personal information within a reasonable scope;

6. Other circumstances as prescribed by laws and national standards.

According to legal regulations, sharing or transferring anonymized personal information, ensuring that the data recipient cannot restore and re-identify the personal information subject, does not constitute external sharing, transferring, or publicly disclosing personal information, and we will not need to notify you or obtain your consent for the preservation and processing of such data.

We will retain your personal information for as long as necessary to provide services. However, if there are legal requirements for a different retention period, if you consent to a longer retention period, or if it is necessary to ensure the security and quality of the service or to resolve disputes, we may extend the retention period within a reasonable scope. Once the retention period has expired, we will delete your personal information or anonymize it according to legal requirements.

Your personal information is generally stored within the territory of the People's Republic of China. If certain products or services involve cross-border data transfers, we will strictly comply with legal regulations and ensure the security of your personal information.

(1) We collect, use, store, and transmit user information in accordance with established industry security standards and protocols, informing you of the purpose and scope of information usage through user agreements and privacy policies.

We conduct background checks on security management personnel and key security positions. We have a comprehensive information security management system and an internal mechanism for handling security incidents. We will implement reasonable and feasible security measures and technical means that meet industry standards to store and protect your personal information against loss, unauthorized access, public disclosure, use, modification, destruction, loss, or leakage. We will take all reasonable measures to protect your personal information, including using encryption technology to ensure data confidentiality and employing trusted protective mechanisms to prevent data from malicious attacks.

(3) We provide our employees with training and assessments on data security awareness and capabilities, enhancing their understanding of the importance of protecting personal information.

Any violation of confidentiality agreements will be subject to accountability.

(4) Please be aware that the internet is not an absolutely secure environment. When you interact with other users via email, SMS, etc., we cannot guarantee that third-party software fully encrypts the transmission of information. Please ensure the security of your personal information and avoid sending personal information through such methods to prevent leakage. We recommend using complex passwords and not sharing your account credentials with others to help ensure the safety of your account and personal information.

We will develop an emergency plan for cybersecurity incidents to promptly address risks such as system vulnerabilities, computer viruses, network attacks, and intrusions. In the event of a network security incident, we will immediately activate the emergency plan, take appropriate remedial measures, and report to the relevant authorities as required.

(1) Personal information breaches, damage, or loss constitute significant security incidents at the company level. We will regularly organize safety drills for team members to prevent such incidents. If such an incident occurs, we will activate the emergency plan with the highest priority, forming an emergency response team from various departments, including security, government relations, and legal, to trace the cause and minimize losses as quickly as possible.

(2) After a personal information security incident occurs, we will inform you in a timely manner about the basic situation of the incident, its possible impacts, the measures we have taken or will take, recommendations for reducing risks, and any remedial measures available to you, in accordance with legal requirements.

Additionally, we will proactively report the handling of personal information security incidents to regulatory authorities as required.

Since different products have different functionalities, the methods provided for controlling personal information may vary; please read the relevant product's privacy policy for further details.

Each business function requires some basic personal information to be completed. You may give or withdraw your consent regarding the personal information we process based on your consent at any time. For example:

(1) You can unlink your Hi-Tech account from third-party accounts in the personal center and manage your search history settings.

(2) If you have granted us certain mobile device system permissions, you can withdraw your authorization through the system settings.

Once you withdraw your consent or authorization, we will not be able to continue providing the services corresponding to that consent or authorization and will no longer process your relevant personal information. However, your decision to withdraw consent or authorization will not affect the processing of your personal information that was conducted based on your consent or authorization prior to the withdrawal.

You can cancel your registered account at any time. You can log in to the personal center and follow the instructions to cancel your Hi-Tech account. Once you cancel your Hi-Tech account, you will not be able to use any Hi-Tech user products and services (except for certain functionalities that do not require registration/login). Therefore, please proceed with caution. To protect your or others' legitimate rights, we will assess whether to support your cancellation request based on your usage of Hi-Tech products and services. For example, if you still have files in your cloud storage, we will not immediately support your request. If you log in to Hi-Tech using a third-party account, you will need to request account cancellation from that third party.

Hi-Tech wishes to accompany you at all times. If, for any special reason, Hi-Tech platform products and services are forced to stop operating, we will notify you as required by laws and regulations via the main page of the product and/or services, through internal messaging, emails, or other suitable means of contact, and will cease the collection of your personal information while also deleting or anonymizing your personal information as required by law.

Under the conditions specified in national laws and regulations and the provisions of the Internet Information Department, if you request to transfer your personal information to a designated personal information processor, we will provide a means for the transfer in accordance with relevant regulations.

For security reasons, you need to provide a written request or other means to prove your identity when exercising your rights. We may first require you to verify your identity before processing your request.

For reasonable requests, we generally do not charge a fee, but we may charge a fee for repeated or excessive requests as deemed appropriate. We may refuse requests that are groundless, require excessive technical means (e.g., need to develop new systems or fundamentally change existing practices), risk the legitimate rights of others, or are impractical (e.g., involve information stored on backup tapes).

We will be unable to respond to your requests as required by laws and regulations in the following situations:

(1) Related to national security or defense;

(2) Related to public safety, public health, or significant public interest;

(3) Related to criminal investigations, prosecutions, trials, and execution of judgments;

(4) Where we have sufficient evidence to show that you have subjective malice or abuse of rights (e.g., your request endangers public safety or the legitimate rights of others, or exceeds the range that can be covered by general technical means and commercial costs);

(5) Responding to the request of the personal information subject would severely harm the legitimate rights of you or other individuals or organizations;

(6) Involving trade secrets;

(7) Related to our performance of obligations prescribed by laws and regulations;

(8) Other situations prescribed by laws and regulations.
