Privacy Policy
This Privacy Policy describes how and why PDF Quick Viewer accesses, collects, stores, uses and/or shares your information when you use our application. Your privacy is very important to our application services, and we are committed to protecting the privacy and security of our users. By downloading and using PDF Quick Viewer, you agree to the terms of this Privacy Policy. If you do not agree to the practices described in this Privacy Policy, please do not use the application.
Automatically collected information
In order to continuously improve the performance of PDF Quick Viewer application and the quality of user services, we will automatically collect the following non-personal information during your use of this application, as described below:
Device information collection: We will collect basic parameters such as device brand, model, operating system version, screen resolution, and obtain device unique identifiers (such as IMEI, Android ID, IDFA, etc., depending on different devices and operating systems), device language settings, and time zone information. By integrating such data, the application can run stably in a multi-device environment, and dynamically optimize the interface layout and function configuration based on device characteristics.
Usage behavior data: The system will record usage data such as the time and frequency of user opening files, the length of a single reading, and the range of pages browsed. By systematically analyzing this type of data, we can deeply explore user usage habits and potential needs, and provide data support for application function iteration and optimization.
Network environment data: We will obtain the network type (WiFi, 4G, 5G, etc.), IP address and network operator information when users use the application. These data help to ensure the stability of the application network connection, support the rapid location and elimination of network faults, and strengthen the application network security protection system.
System abnormality log: When the application crashes, flashes back or other operating errors occur, the system will automatically collect crash log information such as error code, occurrence time, device status and operation behavior at the time. Through professional analysis of log data, the technical team can efficiently locate the root cause of the problem, fix system vulnerabilities in time, and improve the stability and reliability of application operation.
Third-party service data: Because PDF Quick Viewer integrates third-party services, third-party partners may collect some usage data when using related functions. For example, the relevant data obtained by data analysis service providers will assist us in analyzing user behavior from multiple dimensions and continuously promote product function upgrades and service optimization.
We strictly follow the laws and regulations related to data security, and take security measures such as encrypted storage and compliant use for all collected non-personal information to ensure the security and compliance of the data use process.
Use of Information
During the operation of the PDF Quick Viewer service, the collected non-personal information will be used in accordance with the principles of legality, legitimacy and necessity. The specific uses are as follows:
Device information is mainly used to ensure the device compatibility of the application. By analyzing parameters such as device brand, model, operating system version, etc., the adaptation problems of the application on different terminal devices can be identified and solved; according to the screen resolution, language setting and time zone information, the application interface layout and function display are optimized and adjusted to ensure that users can get a good user experience on all types of devices.
Usage behavior data is intended to gain an in-depth understanding of user application usage patterns. By analyzing data such as file opening time, reading time and browsing page range, high-frequency use functions and operation pain points can be identified. Based on the above analysis results, core functions such as file loading speed and reading mode switching are optimized to improve the convenience and efficiency of application operation.
Network environment data is used to ensure the stability and security of the application network connection. By monitoring the network type, IP address and network operator information, the network status can be grasped in real time, and network connection failures can be quickly located and repaired; at the same time, such data can be used to strengthen the network security protection system and prevent network attack risks.
System exception logs play a key role when the application crashes, flashes back and other abnormal situations occur. By analyzing log information such as error codes, occurrence time and operation scenarios, the technical team can quickly locate the root cause of the problem and implement repairs; through statistical analysis of high-frequency abnormal types, preventive measures can be taken in advance to continuously improve the stability of application operation.
Third-party service data will be integrated and analyzed with own data to achieve a comprehensive insight into user usage behavior. Refer to the data provided by the data analysis service provider, scientifically evaluate the priority of function optimization, iterate and upgrade the application interface design and functional modules, and ensure that the application service continues to meet user needs.
All information is strictly in accordance with relevant laws and regulations during use to eliminate any risk of leakage of identifiable user identity information.
