Developer : APPNOVATE LIMITED

Foreword

This statement will clearly and concisely inform you of the personal information processing rules when using the Boost Master application (hereinafter referred to as "the Application"), helping you to fully control your privacy rights. We strictly comply with the requirements of the "Boost Master Privacy Policy" and the "Personal Information Protection Law of the People's Republic of China," adhering to the principles of "minimum necessity" and "purpose limitation." All personal information processing operations will not exceed the scope stipulated in this statement.

It should be clarified that this statement applies only to the services we directly provide and does not cover any third-party products or services. When using third-party features within this application, please be sure to review the privacy policy independently published by that third party to understand their personal information processing rules. We recommend that you carefully read the entire statement, paying particular attention to the core terms highlighted in bold , in order to more fully exercise your legal rights, such as the right to know and the right to make decisions.

I. Your Core Rights and Guidelines for Exercising Them

We protect your right to manage your personal information. The following are the specific ways to exercise this right:

(i) Information Management and Authorization Revocation

1. Personal Information Deletion : We do not store your personal information locally. Uninstalling this application will delete all your personal information.
2. Authorization Scope Adjustment : You can withdraw authorization in three ways: ① Cancel login; ② Disable the corresponding functional module; ③ Modify application permissions in your phone's system settings. After withdrawing authorization, we will immediately cease processing related information, but this will not affect operations previously completed based on legal authorization. Please understand that some specific business functions and services require your information to function. When you withdraw your consent or authorization, we will stop providing you with the corresponding functions and services and will no longer process your related personal information. However, please note that your withdrawal decision will not affect the processing of personal information previously completed based on authorization, and related data processing activities will still be bound by the original authorization.
3. Unsubscribe from marketing messages : You can refuse to receive our marketing messages through "Phone System Settings - App Permissions - Turn Off Push Notifications".

(ii) Account Cancellation and Feedback Channels

1. Account cancellation : Apply for cancellation via "Settings - My Feedback" or by sending an email to chencheng@appnovateltd.com . We will verify your identity and device information before cancellation. This operation is irreversible; after cancellation, all services will be terminated and your information will be deleted.
2. Feedback : If you have any objections to the information processing, you can submit a request through the above-mentioned cancellation channels. We will respond promptly after identity verification. Reasonable requests will not be charged; however, duplicate, high-cost, or impractical requests may be rejected.

（iii）Access Privacy Policy

To ensure you fully understand the complete rules for personal information processing, you can view the full text of this policy within the Boost Master client through the following path: After opening the application, go to the "Settings" module, find and click the "Privacy Policy" option on the "Settings" page, and you will be redirected to the full policy page. If you encounter any issues such as page loading errors or difficulty finding the path during access, you can contact our official customer service channels (such as official email or customer service portal). We will provide timely assistance to ensure you can successfully obtain all information regarding the Privacy Policy.

（iv）Complaints and reports

If an application makes a decision that affects your rights through automated decision-making mechanisms such as algorithms, you have the right to request an explanation and access to remedies.

We generally do not charge fees for your reasonable requests. However, for repeated requests or requests that exceed reasonable limits, we will charge a certain cost fee based on the actual circumstances. We may refuse requests that are unjustifiably repetitive, require excessive technical resources (such as developing a new system or significantly adjusting the existing management model), may infringe upon the legitimate rights and interests of others, or are clearly not feasible.

（v）Informing you of your rights regarding the cessation of operations

If we cease operations, we will promptly cease collecting your personal information, notify you of the cessation of operations individually or by public announcement , and delete or anonymize the personal information we hold in our possession .

II. Contextual Explanation of Application Permissions

We only request necessary permissions when required for specific functions. Denying permissions only affects the use of the corresponding function and does not affect other services.

V. Cookies and Data Security

(i) Rules for using cookies

We use cookies to store your login status, language preferences, and other information to avoid duplicate operations. You can manage or delete cookies in your browser settings, but disabling all cookies may cause some functions to malfunction.

(ii) Full-process safety protection measures

To ensure the security of your personal information throughout the entire process of collection, transmission, storage, and use, we have adopted the following multi-layered protection measures:

1. Technical protection : Your information is encrypted with SSL and HTTPS protocols during transmission, preventing others from intercepting or altering it at will; when stored, it is protected with high-strength encryption algorithms and equipped with a "security guard" (IDS/IPS system) to prevent hacker intrusion; to access this information, you need to pass a "double checkpoint" of token verification and account password, so not just anyone can see it.
2. Internal Management : We regularly provide privacy protection training for employees so that everyone understands how to protect your information; moreover, employees can only access information necessary for their work, and absolutely cannot see anything they shouldn't, to prevent information from being misused.
3. Security Incident Response : In the event of an incident such as information breach, we will notify you via email, push notifications, etc., provide remedial suggestions, and report to regulatory authorities.
4. Storage period : Your information will not be stored indefinitely. It will be deleted immediately once the service is no longer needed or the legally stipulated retention period expires, or converted into anonymous data that cannot be linked to you, thus completely eliminating information security risks.
