Privacy Policy

Last Updated: June 05, 2025

This Privacy Policy aims to detail how wenyanguji.com (hereinafter referred to as "we" or "the Website") collects, uses, stores, and discloses your personal information, helping you understand our commitments and practices regarding privacy protection. We always prioritize user privacy and security, strictly adhere to the principle of minimum necessity in data processing, and ensure compliance with relevant laws and regulations.

I. Scope of Application and Service Overview

This Privacy Policy applies to all users who access or use the wenyanguji.com website (hereinafter referred to as "the Service"). The Service is a website providing book reading, and while offering books, it recommends related videos to users. Its core function is to provide users with public video resources related to book titles through the YouTube API. We only provide technical services to connect users with public web content, do not engage in deep processing of user personal data, nor conduct any personalized recommendations or user behavior analysis. Clicking the above video link represents your agreement to be bound by the YouTube Terms of Service

II. Personal Information We Collect

(1) Personal Information Provided Voluntarily

We only collect necessary personal information during the user login process:

• Mobile Phone Number: You need to actively provide your mobile phone number to complete verification code login. This information is only used to generate a one-time login verification code. After successful verification, we will not store your mobile phone number or any other information associated with this number. The verification code is valid for 5 minutes and will automatically expire if unused, with related records permanently deleted from the server.
• Other Information: In addition to the mobile phone number, we do not collect any other personal information such as name, email, address, or social account.

(2) Non-Personal Information Obtained via API Services

To implement the video recommendation function, we use the YouTube API Service as an API client, involving the following data processing:

• Search Keywords: The book titles you enter in the search box (e.g., Records of the Grand Historian, Analects of Confucius, etc.). Such information belongs to public non-personal data and is only used to generate YouTube search requests. We do not store your search history, and relevant keywords are deleted from the server immediately after each search request is completed.
• Public Video Information: Public data returned by the YouTube API, such as video titles, descriptions, links, and view counts. We only display this information to users, do not associate it with any user identification, nor use it to analyze user preferences or behaviors.

(3) Types of Information We Do Not Collect

We commit never to collect the following information:

• Device information: such as IP address, MAC address, device model, operating system, etc.
• Behavioral data: such as page browsing records, click times, dwell time, etc.
• Cookies and similar technologies: We will not implant any tracking technologies such as Cookies, pixel tags, or local storage in your browser or device, nor collect such information.

III. How We Use Your Information

(1) Sole Purpose of Mobile Phone Number

• Login Verification: Confirm the validity of your mobile phone number via SMS verification code to ensure account access security. This process is assisted by a third-party SMS service provider. We only receive verification results ("valid" or "invalid") and do not store SMS content or complete mobile phone number information.

(2) Logic and Data Isolation for Video Recommendations

• Non-Personalized Recommendations: Recommended content is entirely based on the book titles you enter, obtained through the public search interface of the YouTube API. The recommendation logic is "book title keyword matching + public video sorting on YouTube," without involving user profiles, interest tags, or other personalized algorithms.
• Data Isolation Mechanism: Book titles and user mobile phone numbers are stored completely separately, with no associated records. Your search behavior is independent of your login status – you can still enter book titles in guest mode to get recommendations without logging in.

(3) Prohibited Information Usage Scenarios

We commit never to use collected information for the following purposes:

• Marketing promotions: We will not send you ads via SMS, email, or other means.
• Data sharing: We will not share your personal information or behavioral data with any third parties (including partners or affiliated companies).
• Automated decision-making: We will not conduct user profile analysis, preference prediction, or other algorithm-based automated processing.

IV. How We Store and Protect Your Information

(1) Storage Period and Scope

• Mobile Phone Number: Only temporarily stored during verification and immediately deleted after verification, with no exceptions.
• Book Titles: Only temporarily stored in server memory during search request processing and cleared from memory after the request is completed, without being written to hard drives or databases.
• YouTube Data: Only video metadata (such as titles and links) is cached for page display, with a cache validity period of 24 hours and automatic deletion after expiration.

(2) Security Technical Measures

• Use encrypted transmission protocols (HTTPS) to protect data security during transmission and prevent man-in-the-middle attacks.
• Servers are deployed in compliant data centers with strict access control policies, accessible only to authorized technicians for maintenance purposes, with full audit records of access.
• Third-party services (such as SMS verification code platforms) are contractually obligated to protect data, ensuring their processing complies with this Privacy Policy.

V. How We Disclose Your Information

(1) Principle of No Sharing with Third Parties

We strictly adhere to the "zero-sharing" principle, unless required by laws and regulations:

• We will not provide your mobile phone number to any third parties (including advertisers, data analysis companies, or social media platforms).
• We will not use your search keywords or video viewing records for commercial cooperation or data transactions.

(2) Data Processing Instructions for YouTube API

When using the YouTube API, we only transmit the following information to Google:

• The book titles you enter (non-personal information).
• Necessary technical parameters (such as API request format, version number, etc., without user identification).
  Google's collection, use, and storage of data are governed by its official privacy policy. For details, please refer to: Google Privacy Policy.

VI. Your Privacy Rights and Choices

(1) Rights to Access and Delete

• Since we do not store your personal information, you do not need to apply for data access or deletion. If you believe there is erroneous storage, you can submit a verification request via the contact information at the end of this policy, and we will complete verification and feedback within 3 working days.

(2) Consequences of Refusing to Provide Information

• If you refuse to provide a mobile phone number, you will be unable to use the login function but can still use the video search and recommendation service in guest mode (no login required).

(3) Complaints and Suggestions

You have the right to provide opinions or complaints about our privacy protection measures, and we will respond to the progress of handling via your provided contact information within 15 working days.

VII. Protection of Minors

This Service is not directed at minors under the age of 13 (or lower age limits specified by local laws). If you are a minor, it is recommended to use this Service under the supervision of a guardian. We do not intentionally collect personal information of minors. If we discover that a minor has provided a mobile phone number without guardian consent, we will immediately delete related records and terminate the account (if any).

VIII. Third-Party Link Statement

This Service may contain links to third-party websites such as YouTube. The privacy policies of these websites are unrelated to ours. We recommend that you carefully read their privacy terms when visiting third-party websites, and we assume no responsibility for the actions of third parties.
