1. How We Collect and Use Your Personal Information
1.1 To provide you with a high-quality and stable service experience, we will collect and use personal information in accordance with laws and regulations, following the principles of legality, legitimacy, necessity, and minimization. It is only used to realize service functions or improve service levels.
Specific scenarios are as follows:
1.2 Core Function Implementation
1.2.1 Account Registration and Login: The system generates a unique virtual identifier for the device using a timestamp algorithm. It does not collect personal sensitive information such as name or phone number, nor device hardware identifiers (e.g., serial numbers), reducing privacy association risks and ensuring stable cross-scenario account operation.
1.3 Wallpaper Service Related
1.3.1 Wallpaper Download Function: Download requires file storage permission, used only to save network wallpapers to the local device directory for offline use; refusing authorization only affects the download function, while other functions such as browsing and favorites remain normal.
1.4 Custom Wallpaper Function
1.4.1 Selecting photos from the album requires album access permission, used only to read image data for editing and setting, not for automatic upload or backup; refusing authorization will prevent loading album images, but wallpapers can still be changed using built-in materials, and other functions are not affected.
1.5 Account Security and System Optimization
1.5.1 To ensure account security, optimize service response, and locate issues, the following may be collected:
1.5.2 Device Information: Including device model, system version, identification code (e.g., IMEI), resolution, network/sensor information (e.g., IP, GPS), used for compatibility analysis and anomaly diagnosis.
1.5.3 Log Information: Including hardware/software configuration, access IP, search terms, URL, page dwell time, and other usage details, used for behavior backtracking, popularity assessment, and performance optimization.
1.6 Face Data Policy
1.6.1 Special reminder to you, the facial data collected by this software
We analyze your photos to identify facial feature points (eyes, nose, mouth points) for face processing. We do not collect facial data. After the analysis is complete, all data will be deleted and no data will be saved. Refusing to provide the above information may prevent you from using core functions, but it will not affect the normal use of other features and services.
1.6.2 Purpose and process of collecting facial dataIn order to provide you with special effects related effects, we need to find out the complete process of facial feature points (eyes, nose, mouth points):
（1）Users will upload the selected images to our server through secure encryption methods;
（2）The server analyzes the facial features in the image you uploaded and integrates them into the template you selected;
（3）Once the synthesis is complete, the server will feedback the final visual effect to you through the application;
（4）The synthesized result (i.e., your "creation") will be temporarily saved in a secure, encrypted storage space and will be completely cleared after the production process ends. After the synthesis process is completed, we will immediately delete the facial images you uploaded to the server.1.7 Message Notification Service
1.7.1 Important information such as version updates and activity announcements is pushed through the system notification bar to improve reach efficiency.
1.8 Operational Quality Assurance
1.8.1 Data such as process status, feature usage frequency, crash logs, performance indicators (e.g., CPU/memory usage), and installation channels are collected, some of which are analyzed through third-party platforms (e.g., Umeng) to improve services.
1.9 Other Information Collection
1.9.1 Including application version number, system version, device model, and error logs, used to locate compatibility issues and optimize interaction processes. Special Note: Individual device information and log information are not directly associated with individuals; if combined with identifiable identity information, they are considered personal information and will be anonymized in accordance with the law.
2. Use of Cookies and Similar Technologies
2.1 We use cookies and similar technologies (such as local storage, pixel tags) to collect behavioral data (e.g., browsing history, device information) when you use the service, strictly following regulations and this Privacy Policy. Data is only used with your authorization or to ensure basic services for:
1. Security and Optimization: Verify login status, monitor abnormal logins, and improve page loading speed;
2. Personalized Experience: Save settings such as language and theme to reduce repetitive operations;
3. Content Recommendation: Push relevant wallpapers and interface suggestions based on browsing preferences;
4. Service Improvement: Analyze user behavior to optimize algorithms and solve operational issues.
2.2 Cookie Management Tips
2.2.1 You can clear cookies through your browser settings, but this may cause automatic login to fail, reduce recommendation accuracy, or require reconfiguration of quick settings. It is recommended to weigh the operation based on privacy needs and back up important settings.
3. How We Share, Transfer, and Publicly Disclose Your Personal Information
3.1 Sharing Principles
(1) Authorized Consent: No sharing of personal information without explicit consent, unless the information is completely de-identified (verified by a third party as non-re-identifiable) and limited to compliance scenarios such as technology research and development.
(2) Legal Minimum Necessity: Sharing must comply with regulations, be limited to the minimum data and shortest period necessary to achieve the purpose, and dynamically assess and terminate redundant sharing.
(3) Security and Prudence: Before sharing with a third party, its legality and security qualifications must be assessed, legal agreements signed, and encryption monitoring deployed to ensure transmission security.
3.2 Sharing for Function Realization
3.2.1 When using value-added features, anonymized metadata (e.g., preference tags) may be shared to optimize recommendations. Users can apply to disable this via customer service channels, and processing and feedback will be provided within 15 working days.
3.2.2 Please note: When using the DIY wallpaper and video face swap features, you need to grant access to your photo album and select a photo or video from the album as the material for special effects production before proceeding to the next step. When using these features, we will send the images or videos you select to our third-party AI partner (Tencent Cloud) for special effects processing. You may refuse to grant authorization and thereby stop using the feature.
3.3 Sharing for Security and Statistics
(1) Account Security: Share encrypted device/login information with certified institutions, used only for risk control defense; partners must maintain confidentiality.
(2) Anonymized Statistics: Share aggregated data (e.g., crash rates) after k-anonymity and differential privacy processing to ensure irreversible identification.
(3) Academic Research: After ethical review, share de-identified data (removing PII) with research institutions, limited to public welfare purposes and prohibited for commercial use.
3.4 Participation in Marketing Activities
3.4.1 When participating in marketing activities, the system may require sensitive information such as name, contact information, shipping address, and bank account to ensure the activity and reward distribution. Sharing of such information strictly follows the "minimum necessity" principle, is only provided to third parties with your authorization, and is limited to identity verification or reward distribution.
3.4.2 Description of Third-Party Types:
(1) Service Platforms: Technical parties such as payment and logistics, only obtain necessary service information (e.g., account, address) and are independently responsible.
(2) Technology Suppliers: Software and hardware service providers, share device/behavior data to optimize activity experience.
(3) Advertising Service Providers: Use only anonymized behavioral data to generate anonymous profiles for precise targeting or functional optimization.
