1. Introduction

This Privacy Policy explains how 优知 (“we”, “us”, or “our”) collects, uses, stores, discloses, and protects the personal and non-personal information of users (“you” or “users”) who access and use the Vast Drama mobile application (the “App”), a short drama streaming and reward-earning platform available on the Google Play Store.

This policy complies with Google Play Developer Policies, Android Data Safety requirements, the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and other applicable global privacy laws. By downloading, installing, or using our App, you acknowledge and agree to the data practices outlined in this Privacy Policy. If you do not agree with this policy, please do not use the App.

2. Information We Collect

We collect two categories of user information: information you voluntarily provide and information collected automatically during App operation. All collected data is only used for App operation, experience optimization, reward service delivery, and compliant advertisement display, and will not be used for illegal purposes.

2.1 Information You Voluntarily Provide

• Account & Profile Data: When you register or log in to the App, we may collect your nickname, unique user ID, and profile settings. Real-name authentication is not mandatory for basic App usage, and we will not forcibly collect your real identity information.

• Contact and Payment Information (Voluntary Provision): To facilitate in-app reward distribution, earnings withdrawal, rights verification, and user follow-up support, you may voluntarily provide us with your phone number, email address, and payment account information. Such information is solely used for reward settlement, withdrawal reconciliation, payment verification, abnormal withdrawal troubleshooting, and customer service communication. We will never use this information for marketing harassment, data resale, or any unrelated purposes. You have the full right to refuse to provide the above information. Refusal will only disable cash withdrawal and reward redemption functions and will not affect your basic use of the App, including drama watching and public content browsing.

• Reward & Redemption Data: To provide in-app task rewards, coin bonuses, and cash redemption services, we record your reward balance, withdrawal records, transaction timestamps, and operation logs. This data is used for reward settlement, eligibility verification, and prevention of fraud and malicious reward harvesting.

• Support Communication Data: When you contact our customer support via official email, we retain your inquiry content, contact information you actively provide, and communication records to resolve your issues efficiently.

2.2 Automatically Collected Information

• Device Information: We automatically collect device model, operating system version, device language, screen resolution, network type, and Android Advertising ID (AAID) for device compatibility optimization, stable advertisement delivery, and anti-fraud verification.

• Usage Analytics Data: We record your in-app behaviors, including drama viewing duration, browsing history, function click logs, task completion status, and daily activity data, to optimize content recommendations, iterate product functions, and improve user experience.

• Log Data: Our servers automatically generate access logs, including access time, IP address, App crash logs, and system anomaly records, to ensure App stability, troubleshoot failures, and fix technical issues.

3. How We Use Your Information

We only use collected user data for legitimate, specified, and agreed service purposes without unauthorized over-range usage. The specific usage scenarios are as follows:

• Provide, maintain, and optimize core App services, including short drama streaming, content updates, and normal operation of reward tasks;

• Verify user identity, calculate in-app earnings, record reward data, and process legal and compliant withdrawal applications;

• Deliver personalized drama content recommendations and in-app notifications based on your browsing preferences;

• Display in-app advertisements through compliant third-party advertising platforms;

• Prevent fraud, malicious traffic brushing, and abnormal account operations to protect the legitimate rights and interests of the platform and all users;

• Analyze operational data, optimize product functions, fix bugs, and upgrade user experience;

• Respond to user consultations, feedback, and rights protection requests;

• Comply with applicable laws, regulations, and Google Play compliance requirements.

4. Information Sharing and Disclosure

We will never sell, rent, or lease your personal information for independent commercial purposes. We only share necessary anonymized data with authorized third-party service providers under compliant conditions, and all partners must strictly abide by global privacy protection laws.

• Advertising Service Providers: We cooperate with compliant advertising platforms such as Google AdMob. We share anonymized device data, advertising IDs, and desensitized usage data to support normal ad display, data statistics, and non-intrusive targeted advertising, without sharing any sensitive personal information.

• Data Analytics and Technical Service Providers: We may share aggregated and anonymized user data with third-party analysis tools for App operation statistics, behavior analysis, and technical operation maintenance.

• Legal Compliance Requirements: We may disclose user information if required by laws, judicial procedures, or governmental regulatory authorities, or when necessary to protect the legitimate rights, property, and public safety of us, users, and the public.

All third-party partners have signed data confidentiality agreements and are prohibited from using user data beyond the authorized scope.

4.1 Third-Party Ad SDK Data Processing Statement

The App integrates mainstream third-party advertising SDKs, including but not limited to Google AdMob, AppLovin, and Pangle (TikTok For Business), to support in-app advertisement display, traffic monetization, data statistics, and anti-fraud verification for reward tasks. These SDKs may automatically collect and process anonymized device and usage data in compliance with platform rules and Google Play policies.

Data collected by advertising SDKs may include: Android Advertising ID (AAID), device brand and model, operating system version, network status, App package information, ad interaction data (impressions, clicks, viewing duration), anonymous statistical data, and non-precise regional location information. All data is aggregated and anonymized and cannot be used to identify individual users.

We do not control the independent data processing behaviors of third-party advertising platforms. Ad-related data collection and usage are subject to the respective privacy policies of Google AdMob, AppLovin, and Pangle. We recommend you review their official privacy policies for detailed rules.

Data processed by third-party ad SDKs is used for regular and personalized ad delivery, ad performance statistics, traffic quality verification, monetization anti-cheating detection, and platform service optimization. You may disable personalized advertising through your device system settings to decline targeted ad delivery.

5. Data Storage and Security

We store user data on encrypted and compliant servers and formal data centers. We adopt industry-standard encryption technologies, permission control, server security monitoring, and regular maintenance to prevent unauthorized access, leakage, tampering, loss, and abuse of user data.

User data is only retained for the period necessary to provide services and meet compliance and risk control requirements. We will delete or anonymize user data timely when it is no longer required.

Please note that no network transmission or electronic storage technology can guarantee absolute data security. We will fully protect your data security but cannot guarantee absolute safety during data transmission.

6. User Rights

In accordance with GDPR, CCPA, and other global privacy laws, you have the following legal rights regarding your personal data:

• Right of Access: You may request access to your personal data collected and stored by us;

• Right of Rectification: You may request us to correct inaccurate or incomplete personal data;
